Founding Full Stack Engineer at ProofofSkill · Remote only · 2 - 5 years · ₹4L - ₹7L / yr (ESOP available) · Raised funding · Remote only · Posted 22 Sep 2026

We’re reimagining how users interact with SaaS products and looking for a founding engineer to help build the first version from zero alongside a founder with experience building at HubSpot, Asana, and Datadog.
Role
We are hiring a Founding Engineer with strong frontend, product, and design instincts. You will work directly with the founder to shape the product, prototype quickly, make architecture decisions, think through user problems, and turn an early thesis into a working product.
The ideal person is a builder — someone who can move from an ambiguous idea to prototype, from prototype to usable product, and from usable product to scalable architecture. You should be excited by the opportunity to change how users interact with software and, eventually, the internet itself.
What You’ll Build
You will help build the first version of our core product, including:
- An SDK powered by frontier AI models and modern product experience protocols
- Backend services with rules, resolution logic and intent inference
- Early prototypes that help us test different wedges with customers
- Production-ready systems as the product direction becomes clearer
This role will likely span React, TypeScript, Next.js, backend APIs, databases, event tracking, and AI-assisted workflows.
Required Experience
- 2–5 years of software engineering experience, or equivalent demonstrated ability
- Strong frontend engineering experience with React and TypeScript
- Ability to design clean, scalable frontend component architecture
- Experience with backend APIs and databases
- Experience taking ambiguous product ideas and turning them into working software
Strong Plus
- Experience building 0-to-1 products
- Experience at an early-stage startup
- Experience building SaaS products
What Success Looks Like
In the first 30 days, you will:
- Understand our thesis, target customer, and product direction
- Help refine the first product wedge
- Build and iterate on early prototypes
- Set up core frontend and backend foundations
- Move quickly across product, design, and engineering decisions
In the first 60–90 days, you will:
- Ship the first usable product prototype
- Help build demo experiences that clearly communicate the product vision
- Create the first version of the adaptive frontend architecture
- Help test the product with early users, customers, or design partners
- Identify what should become production-grade versus what should remain experimental
Leadership Opportunity
This is a founding role with significant upside.
For the right person, strong performance can lead to a leadership position as the company grows. We are looking for someone who can become a long-term technical and product partner — someone who can help build the first version, shape the architecture, hire future engineers, and potentially lead major parts of the engineering organization.
This is an opportunity to join at the earliest stage and help define both the product and the company.
Why Join
- Build from zero with high ownership
- Work directly with the founder
- Help create a new category of software
- Own meaningful technical decisions from day one
- Opportunity to join the leadership team as the company scales

Founding Full-Stack Engineer / Technical Lead — X.re
We are building X.re — an AI-first CRM built specifically for real estate companies.
X.re is not another generic CRM. It is being designed around the real estate sales funnel, with AI-powered WhatsApp conversations, AI voice, lead scoring, workflow automation and advertising intelligence built into the system.
The product is already being built and is currently being tested with a real estate pilot client.
We are now looking for a senior engineer who can take ownership of the existing codebase and help take it from AI-assisted development into a robust, production-ready SaaS product.
What you'll be doing
- Take ownership of an existing Next.js + TypeScript codebase.
- Understand the existing architecture, database structure, APIs and application flows.
- Conduct a thorough engineering review and identify production, security, scalability and reliability risks.
- Refactor and improve the code where required rather than blindly rewriting the system.
- Build and maintain production-quality frontend and backend features.
- Design and maintain APIs, database models and integrations.
- Work on a multi-tenant SaaS architecture where each real estate brand has its own workspace and data isolation.
- Work closely with AI/LLM-powered features including chat, voice and lead intelligence.
- Work on WhatsApp Business API integrations, webhooks and messaging infrastructure.
- Build reliable automation and workflow functionality.
- Implement proper authentication, authorization, data isolation, logging, monitoring and error handling.
- Help establish engineering standards, testing and deployment practices.
- Eventually build and lead the engineering team as X.re scales.
What we're looking for
We are looking for someone who has strong engineering judgment, not someone who simply knows a list of technologies.
You should be able to:
- Enter an unfamiliar codebase and understand it quickly.
- Identify what is well designed and what is technically risky.
- Take an MVP and turn it into production-grade software.
- Make pragmatic architectural decisions.
- Think about security, scalability, reliability and maintainability.
- Work independently and take ownership.
- Read and review code generated or assisted by AI.
- Know when AI-generated code is acceptable and when it needs to be redesigned.
- Build rather than just manage developers.
Technical requirements
Strong experience with:
- TypeScript
- Next.js / React
- Node.js
- REST APIs
- PostgreSQL / SQL
- Modern SaaS application architecture
- Cloud deployment
- Git and production development workflows
Experience with the following is a strong advantage:
- AI/LLM applications
- WhatsApp Business API
- Webhooks
- Multi-tenant SaaS
- API integrations
- Docker
- AWS or similar cloud platforms
- CI/CD
- Observability and production monitoring
One important thing
This is not a greenfield project.
The existing product has been built significantly with AI-assisted development.
We are specifically looking for an engineer who is comfortable inheriting an existing codebase, understanding it deeply, challenging its assumptions, fixing what needs fixing, and taking responsibility for making it production-ready.
You will not be expected to rewrite everything just because it wasn't originally written by you.
Why this role is different
You won't just be implementing tickets.
You'll have significant influence over:
- Engineering architecture
- Production readiness
- Technical standards
- Infrastructure
- AI integration strategy
- Product engineering decisions
- Future engineering team structure
If things go well, this role can grow into Head of Engineering / CTO-level ownership as X.re scales.
Location
Hyderabad preferred. Remote candidates across India may be considered for the right candidate.
Compensation
₹20–35 LPA + ESOP
Compensation will depend on experience and level of ownership.

Worql is building the contract and delivery infrastructure for the US-India engineering corridor. This is a founding-level engineering role. The bar is high, the ownership is real, and you'll work directly with the founder.
What you'll do: ship the core product end to end. Our Next.js app assembles US-India contracts from a vetted clause library, runs a multi-pass LLM pipeline, and verifies delivery through a GitHub-integrated layer. You own features from schema to UI, ship them, and prove they work. No hand-holding, no ticket-churning.
You must have:
- Strong TypeScript and Next.js (App Router). Not coursework, shipped code.
- Real, hands-on experience building with LLM APIs (Anthropic, OpenAI, or similar): structured output, retries, handling failure modes. If you've only followed tutorials, this isn't for you.
- Solid Postgres and Prisma, clean Git and PR hygiene.
You'll stand out if you've built with RAG, prompt pipelines, or evals, and if you can defend your design decisions rather than just generate code.
The deal: full-time, remote, direct founder access, real ownership from week one. We're hiring one exceptional engineer, not five average ones. Prove yourself in the first 60 days and this converts to a market-rate full-time seat. If your current work is beneath you and you're hungry to own hard problems, this is where you show it.
The web is about to gain a second interface
Today, websites are designed for people. Agents must interpret pages, hunt for controls, and imitate clicks to accomplish anything.
We believe that will change. Websites will expose their capabilities directly to agents: structured, testable interfaces that work alongside the human experience. WebMCP is an early step toward that future. Signett is building the developer platform around it.
Our goal is to make creating an excellent agent interface as normal as building an API or testing a user interface.
The foundational product already exists. Signett has a public TypeScript library, documentation, benchmarks, real-world integrations, a website, and a Chrome extension. You would not be joining to turn a slide deck into an MVP. You would be joining to discover what makes a promising product become something developers genuinely adopt.
See it at signett.ai.
The opportunity
You would be Signett’s first hire and would have unusual ownership over the product’s direction.
Your job is to run one loop repeatedly:
- Find an external developer or team with a real reason to make its website agent-ready.
- Work inside its codebase and ship the integration.
- Identify what made the process difficult.
- Fix that friction yourself—in the library, documentation, testing tools, or extension.
- Publish what you learned so the next integration becomes easier.
You will move between engineering, product discovery, developer experience, and early distribution. There will be no handoff between those functions because, initially, you are the person connecting them.
The work could help establish how developers build and test agent interfaces for the web. It could also reveal that our present assumptions are wrong. Either outcome requires someone who cares more about finding the truth than defending the existing product.
The first 90 days
The initial targets are deliberately concrete:
- Five external teams attempt the 30-minute integration.
- At least three ship a real workflow without founder intervention.
- Two remain active or request a paid capability such as shared history, CI, analytics, or evaluations.
- Two reference integrations and case studies become public.
By the end, we should know which part of Signett developers truly value—exposure, testing, reliable execution, the Inspector, evaluations, or something we have not yet recognized.
You may be a strong fit if you have
- Six to ten years of experience as a product-oriented full-stack or frontend engineer.
- Strong TypeScript, React or Next.js, browser API, and Playwright or Cypress experience.
- Built SDKs, developer tools, browser tooling, API infrastructure, or observability products.
- Personally helped developers adopt something through documentation, examples, workshops, open-source work, or direct integrations.
- Enough commercial instinct to find a design partner, lead the conversation, and turn the resulting work into a useful public case study.
- The judgment and autonomy to make progress without daily direction.
- Clear writing and demonstration skills in addition to strong engineering ability.
Experience with WebMCP or MCP is helpful but not required. Curiosity and the ability to learn an evolving standard matter more. The WebMCP proposal is public at github.com/webmachinelearning/webmcp.
The anti-sell
Signett has a product, but it does not yet have proven product-market fit. Adoption is the open question, and answering it is the core of this role.
You should not join if:
- You want a role devoted entirely to writing code handed to you through a roadmap.
- You expect someone else to find users, conduct interviews, write documentation, or publish the work.
- You need a large team, established processes, or daily management to be effective.
- Your experience is primarily managing mature organizations rather than building from ambiguity.
- Your main strength is developer content without production software behind it.
- You want to research or train models rather than build browser-based products developers use.
- The uncertainty of an emerging standard makes you uncomfortable.
- You need the stability and specialization of a conventional engineering position.
.
This is not a comfortable job with a “founding” title attached to it. It is a chance to take a technically serious, public product and prove—or disprove—that it deserves to become an important company.
How we will start
We begin with a paid four-to-six-week project involving a real external TypeScript application, not a synthetic coding exercise.
The purpose is for both sides to experience the actual work: finding a useful integration, shipping it, learning from developers, and improving Signett. If the collaboration works and the evidence supports continued investment, the intended path is a permanent, full-time role.
The work is fully remote. Compensation, location, time-zone overlap, and the terms of the initial project will be discussed transparently before the process begins.
