What is a founding full stack engineer?

A Founding Full Stack Engineer is an early, core technical team member at a startup who is responsible for building both the front-end and back-end of the company's product. This role goes beyond typical engineering, often involving product decisions, architecture design, and collaborating directly with the founders. Founding Full Stack Engineers help shape the company's culture, technical direction, and can have significant equity stake. Their work is crucial in taking the business from idea to launch, often in a fast-paced, resource-limited environment.

What are the key skills and qualifications needed to thrive as a founding full stack engineer?

To thrive as a Founding Full Stack Engineer, you need expertise in both front-end and back-end development, deep knowledge of programming languages like JavaScript, Python, or Ruby, and experience with scalable architectures, often backed by a degree in computer science or equivalent experience. Familiarity with frameworks (React, Node.js, Django), version control systems (Git), cloud platforms (AWS, GCP), and DevOps practices is typically required. Strong problem-solving, initiative, adaptability, and excellent communication distinguish successful candidates, enabling effective collaboration in a startup environment. These skills and qualities are crucial for building robust products rapidly and influencing the company's technical direction from its early stages.

What unique challenges might a founding full stack engineer face when joining an early-stage startup?

As a Founding Full Stack Engineer at an early-stage startup, you'll often balance building core product features with setting up foundational technical infrastructure. This role typically requires wearing multiple hats, from architecting systems and writing code to making critical technology decisions and collaborating closely with non-technical founders. You may encounter challenges such as ambiguous requirements, shifting priorities, and limited resources, but you'll also have significant influence over the company's technical direction. The dynamic environment encourages rapid learning and offers accelerated career growth, particularly for those who thrive in fast-paced, collaborative settings.

Job description

Become a part of our caring community
The Lead Software Engineer codes software applications based on business requirements. The Lead Software Engineer works on problems of diverse scope and complexity ranging from moderate to substantial.

As Centerwell builds its AI engineering function from the ground up, we need a platform foundation strong enough to support everything that comes next. As Lead Full-Stack Engineer focused on platform and API engineering, you will design and build the service layer that connects AI capabilities, data systems, and product frontends-setting the standards for how services are built, secured, and operated across the team.

You will work with meaningful architectural scope, making decisions that span API design, security patterns, and deployment practices. The platform you build will serve care teams and patients across hundreds of Centerwell clinics. If you want to build platforms that others build on-and do it in service of better primary care-this is the role for you.

Key Responsibilities

  • Platform and API Architecture:** Design and lead development of core backend services, REST and GraphQL APIs, and service-to-service integrations that connect all layers of Centerwell's AI product stack.

  • Security and Compliance by Design:** Establish patterns for authentication, authorization, rate limiting, PHI access control, and audit logging. Ensure HIPAA compliance is embedded in platform design from day one-not bolted on after the fact.

  • AI and LLM Integration Patterns:** Define and implement reusable patterns for integrating AI capabilities into product APIs, including LLM routing, streaming responses, tool orchestration, and model output handling.

  • Observability and Reliability:** Build logging, monitoring, and alerting infrastructure so the platform is operable and debuggable at scale.

  • Full-Stack Feature Delivery:** Contribute to product feature development end-to-end using TypeScript and Next.js, from server-side APIs to rendered UI.

  • Architecture Reviews and Standards:** Drive architecture reviews and define backend engineering standards that the full engineering team builds on.


Use your skills to make an impact

Required Qualifications

  • B.S. or M.S. in Computer Science, Engineering, or a related field (or equivalent experience)

  • 8+ years of software engineering experience with deep expertise in backend and platform engineering

  • Strong proficiency in TypeScript and/or Python for API and service development

  • Proven track record building scalable, production-grade REST or GraphQL APIs

  • Solid understanding of authentication (OAuth2, OIDC), API security patterns, and authorization model design

  • Working knowledge of HIPAA requirements, particularly secure transmission, storage, and access control for PHI

  • Experience with Next.js and React sufficient for full-stack feature contribution

  • Demonstrated ownership of complex backend systems end-to-end, from architecture through production operation

  • Hands-on experience with AI-assisted development tools and LLM coding harnesses (Claude Code, Pi Agent, Cursor, Codex, or similar)

Preferred Qualifications

  • Experience in healthcare, financial services, or other highly regulated industries

  • Exposure to event-driven architecture, microservices, or API gateway patterns at scale

  • Familiarity with AI/LLM integration patterns, including streaming APIs and tool-use orchestration

  • Experience in a greenfield or team-founding engineering environment
