Full stack engineer

Full-Stack Engineer (Backend Heavy)

Experience: 4–6 Years | Function: Engineering — Product | Location: On-site

About Us

We’re building the next generation of AI-powered business software, and we’re looking for people who want to shape that future with us. With Lumen, we’re reimagining how users interact with CRM — moving beyond screens, menus and dashboards to an intelligent interface where users can simply ask AI to take actions, retrieve knowledge, generate insights and get work done. With Agent Studio, we’re enabling businesses to build, test and deploy their own AI agents for real-world workflows. And with Invorto, we’re bringing AI to voice, allowing businesses to create intelligent voice agents tailored to their customer and operational use cases.

What makes this especially exciting is the stage and scale of the opportunity. You’ll get to work on genuinely hard problems across LLMs, agents, reasoning, orchestration, voice AI, evaluation, reliability and enterprise security — not as isolated experiments, but as products used in real business workflows. You’ll have the opportunity to build zero-to-one, own meaningful parts of the product end-to-end, work closely with customers, experiment rapidly, and see your work reach production at scale.

Why join now? Because the playbook for enterprise AI is still being written. You won’t just be implementing someone else’s roadmap — you’ll help define the product, architecture and experiences that become that playbook. Expect high ownership, fast iteration, hard technical and product problems, direct customer impact, and the chance to build AI systems that have to work reliably in the real world — not just in a demo.

About the Role

We are looking for a Full-Stack Engineer with a strong backend bias to help build end-to-end product experiences across Lumen and Agent Studio. You will own features from database and API design through to the front-end experience, working closely with product and design to ship AI-powered experiences that real business users depend on every day.

What You’ll Do

Design and build backend services and APIs in Python that power core product and AI-agent features.

Build front-end interfaces and experiences that let users interact naturally with AI agents, insights and CRM workflows.

Own features end-to-end — from data modeling and backend logic to UI implementation, testing and release.

Work with product managers and designers to translate requirements into well-architected, scalable systems.

Integrate with LLM-based and agentic backend systems built by the AI/ML engineering team.

Optimize application performance, reliability and code quality across the stack.

Engage directly with customers and customer success teams to understand workflows, triage issues and inform roadmap decisions.

What We’re Looking For

4–6 years of professional full-stack engineering experience, with a clear backend-heavy skill set in Python.

Strong experience designing and building REST/GraphQL APIs, data models and scalable backend services.

Working proficiency with modern front-end frameworks (e.g., React) to build and integrate user-facing features.

Experience with relational/NoSQL databases, caching and cloud infrastructure.

Ability to move fast in a zero-to-one environment while maintaining code quality and system reliability.

Strong communication skills — this is a customer-facing role, and you will be expected to clearly articulate technical concepts, decisions and trade-offs to both technical and non-technical stakeholders, including customers.

Good to Have

Experience building features on top of LLM or AI-agent backends.

Prior experience in CRM, SaaS or enterprise business applications.

Exposure to real-time or voice-based product interfaces.

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

Company: CombineHealth AI

Location: Bangalore, India (Work from Office — 4 days/week)

Experience: 3+ years

Employment Type: Full-time

About Combine Health

Combine Health is building an AI workforce for healthcare revenue cycle management (RCM) — agentic AI systems that automate medical coding, billing, claims, and denial management, and reason through payer policy for healthcare providers in the US. Backed by Y Combinator and Silicon Valley investors, we work with hospitals and health systems to eliminate revenue leakage and reduce manual, error-prone billing work.

We're a small, fast-moving team. Every engineer here owns real product surface area from day one — there's no hiding behind process at a 12-person company.

The Role

We're looking for a Full Stack Engineer to build and ship features across our AI-driven RCM platform — from the interfaces our customers use to review claims and denials, to the backend services that power our AI agents. You'll work closely with founders and a small engineering team, moving fast on a product that directly affects hospital cash flow.

This is not a role where requirements arrive fully specified. You'll be expected to help define what to build, not just how.

What You'll Do

• Design, build, and ship full stack features across the product — from UI to APIs to data models
• Build interfaces for complex, data-heavy workflows (claims review, denial queues, coding dashboards) that need to be fast and legible, not just functional
• Work with backend services that integrate with AI agents, payer systems, and healthcare data sources
• Own features end-to-end: design, implementation, testing, deployment, and iteration based on customer feedback
• Collaborate directly with founders and product on prioritization — this isn't a "tickets handed to you" role
• Write clean, maintainable code and help set engineering practices as the team scales
• Debug and resolve production issues quickly in a live, customer-facing system

What We're Looking For

• 3+ years of professional experience building full stack web applications in production
• Strong hands-on experience with a modern frontend framework (React or similar) and backend framework/language (Python, Node.js or similar)
• Comfort working across the stack: REST/GraphQL APIs, relational databases (Postgres/MySQL), and basic infra/deployment (Docker, cloud platforms like AWS/GCP)
• Ability to take a loosely defined problem and ship a working solution without waiting for a detailed spec
• Solid fundamentals in data modeling, system design, and debugging complex issues in production
• Startup mindset: comfortable with ambiguity, fast iteration, and wearing multiple hats
• Strong communication — you'll be working directly with a small team and need to explain trade-offs clearly

Good to have:

• Experience integrating with AI/LLM APIs or building AI-adjacent product features
• Prior experience at an early-stage startup (seed to Series A)

Why Join Combine Health

• Work on a product with real, measurable impact — faster payments, fewer denials, less manual work for healthcare teams
• Small team, high ownership — your work ships and matters immediately
• Backed by Y Combinator and top investors, early enough that your decisions shape the product
• Direct access to founders and fast decision-making, no layers of bureaucracy

● The school that you come from and organizations where you have worked earlier. Personality Expectations We believe that it takes a certain type of personality to do a certain kind of role well. 

● Thoughtful & Analytical: Unlike a sales role, this role requires deep analytical ability and thoughtfulness. You don't just "hit goals at any cost"; you architect sustainable solutions that prevent future debt. 

● The "Pack Leader" Mentality: You are competitive, but you understand that your team's win is your win. You shift from getting a dopamine hit from solving a bug yourself to getting a hit from unblocking your team to solve ten bugs. 

● High Ownership of Outcomes: You don't just care that the code was written; you care that the feature was delivered, works for the customer, and didn't break production. You expect very highly of yourself and being less than ideal anywhere almost pains you. 

● Resilience: You possess the mental endurance to push through complex technical constraints and tight deadlines without losing your cool. 

● Uncompromising Values: On the other side, there is only one thing that we care for apart from performance - your values. We have room for mistakes on the performance side, we have no room for mistakes on your values.
