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.

Roles and Responsibilities

Build features across the stack — Implement product features that span the React frontend, the GraphQL federation, the Node.js microservices, and the underlying Postgres and ClickHouse stores.
GraphQL federation work — Add types, resolvers, and subgraph capabilities to the federated Platform API. Keep subgraph boundaries clean. Respect RBAC enforcement at the federation layer.
Developer experience surfaces — Lift NPS through intuitive UI/UX, fast onboarding, in-browser testing, clear error states, code-snippet generation, and fast time-to-first-successful-call.
Billing and commerce features — Ship subscription, plan, invoice, payout, and overage features that touch Stripe / PayPal webhooks, the billing state machine, and the usage ledger.
API catalog and discovery — Improve marketplace search and the API listing experience, including the ranking signals that flow in from the analytics and search stack.
Observability and quality — Instrument every feature you ship — logs, traces, and metrics are part of the definition of done, not a follow-up ticket. Write the alerts that page you, not someone else.
Testing discipline — Own unit and integration tests for everything you ship; contribute to the end-to-end and contract test suites that protect the federation and the billing path. A feature without tests is not done.
On-call and incident response — Take part in on-call rotations; investigate proxy errors, GraphQL federation timeouts, and billing webhook anomalies. You build it, you run it.
LLM-assisted engineering — Use LLM-based coding and agentic tooling to evolve how features are shipped, reviewed, and tested.

What Success Looks Like

Features you ship measurably improve activation, time-to-first-successful-call, and developer NPS quarter over quarter.
The GraphQL federation surface you touch stays fast, well-typed, and intuitive for the next engineer.
Billing, subscription, and overage flows you build are accurate, auditable, and replayable — providers and consumers trust the numbers.
ou ship at a confident cadence — PRs land daily, deploys are routine and boring, regressions are rare.
You leave the code, the docs, and the tests in better shape than you found them.

What You Bring

4–7 years of full-stack product engineering experience, with non-trivial work on production systems used by real customers.
Strong TypeScript/Node.js; comfort writing both frontend (React) and backend services.
Hands-on GraphQL experience — ideally federation (Apollo Federation / Mercurius / similar), schema design, subgraph composition, persisted queries, performance tuning.
Solid SQL and comfort with MySQL or Postgres in production; bonus for ClickHouse or Redis experience.
Familiarity with AWS (EKS, Lambda, Aurora) and containerised deployment on Kubernetes.
Comfortable with modern observability, feature flags, and CI/CD pipelines.
Care for developer experience — APIs you would want to consume, docs you would want to read, errors you would want to debug.
Bonus: experience with billing/commerce systems (Stripe / PayPal), API gateways, rate-limiting, agent protocols (MCP, A2A, x402), or LLM-based developer tooling.
You are pragmatic, ship-oriented, and comfortable in a system big enough that no one person knows all of it.

About Vijay Sales

Vijay Sales is a consumer electronics and appliances retailer, selling through its stores across India, its website and its app.

Our technology team builds the software the business runs on: order management, customer support automation over WhatsApp, reviews and ratings, and the dashboards our operations teams use every day.

The role

We are hiring full stack engineers who can take a feature from spec to production across React, Node.js and MongoDB.

You will work on customer-facing and internal products, often both in the same week. One sprint may be a review submission page used by customers on their phones. The next may be an API that pulls order status from our order management system for the support bot.

We are looking for engineers with 3 to 6 years of experience who are comfortable owning both the front end and the back end of what they ship.

What you'll do

Build responsive, mobile-first interfaces in React using our in-house UI component libraries.
Design and build REST APIs and background services in Node.js.
Model data in MongoDB and keep queries fast as collections grow.
Integrate with the systems the business runs on: order management, ERP, point of sale and ticketing.
Build messaging flows over WhatsApp, email and SMS, including delivery tracking, retries and fallbacks.
Work with the conversational AI team to expose order, invoice and support actions to the customer support bot.
Write tests, review code and own your features in production, including monitoring and fixing what breaks.
Work directly with product and operations teams to turn a business problem into a working release.

Our stack

React, Node.js and MongoDB are the core. Everything else in the table is what you will connect to or build alongside.

Front end: React, with Vijay Sales' in-house UI component libraries
Back end: Node.js services and REST APIs
Database: MongoDB
Messaging: WhatsApp Business, Amazon SES for email, RCS and SMS as fallback
Conversational AI: LangChain and Rasa, behind the customer support bot
Business systems: Order management (OMS), ERP, POS, Ticketing Systems

What we're looking for

3 to 6 years of professional experience building and shipping web applications.
Strong JavaScript and TypeScript fundamentals: async patterns, the event loop, modules, error handling.
Solid React skills: hooks, state management, component design, performance on low-end mobile devices.
Hands-on Node.js experience: building REST APIs, authentication with JWT, role-based access, input validation.
Working knowledge of MongoDB: schema design, indexing, aggregation pipelines.
Experience integrating third-party APIs and webhooks, and handling their failures gracefully.
Comfort with Git, code review, automated tests and CI/CD.
Clear written and spoken communication. You will talk to operations and business teams, not only engineers.

Nice to have

Experience with the WhatsApp Business API, Gupshup or similar messaging platforms.
Exposure to LLM application development: LangChain, retrieval, tool calling, or bot frameworks such as Rasa.
Background in retail, e-commerce or order management systems.
Experience integrating with ERP or POS systems.
Familiarity with AWS, Redis and message queues.
React Native or other mobile app experience.

Why join and how to apply

Your work reaches real customers and store teams quickly. There is very little distance between a release and the people who use it.
You own features end to end, from the first conversation with the business team to production.
You get hands-on exposure to conversational AI and LLM-based products alongside core full stack work.
