Senior Full Stack Engineer (LEAD)

Position: Senior / Lead Full Stack Engineer

Location: Remote

Duration: 6 Months To Hire Work Arrangement: 100% Remote

The Opportunity

We're building and extending customer- and internal-facing applications on top of data and AI platform - portals, APIs, and auth/gateway layers that sit in front of search, inference, and data products. The work spans UI through API to data access, with real production constraints around security, multi-tenant access, and reliability. You will own features end-to-end: design and ship frontend experiences, implement backend APIs and integrations, and keep the path from browser to data clean, tested, and deployable. This is a hands-on build role with strong mentorship and direct exposure to architecture decisions.

What You'll Do

• Build and maintain frontend applications with React / Next.js — pages, components, forms, and data-driven UI.
• Design and implement backend APIs (Python) - REST/JSON endpoints, auth-aware access, validation, and error handling.
• Integrate frontend and backend: API contracts, auth flows (JWT / session), loading and error states, and end-to-end feature delivery.
• Work with data stores and platform services (Postgres/Prisma, BigQuery clients, Redis, object storage) as features require.
• Collaborate on gateway and auth boundaries (tokens, permissions, service-to-service calls) with platform engineers.
• Write tests and documentation for UI and API changes; land work through Git-based PRs and CI/CD.
• Instrument and debug production issues across the stack — browser, API, and dependency failures.
• Support SOC 2-aligned practices: least-privilege access in the app layer, secrets handling, change control, and audit-friendly logging.
• Partner with data, platform, and product stakeholders on scope, trade-offs, and delivery.
• Participate in design discussions, surface trade-offs, and propose improvements as you encounter them in the code.

Required Qualifications

• 8-11 years as a full stack engineer (or equivalent split frontend + backend experience).
• Strong frontend skills: React (and preferably Next.js), TypeScript/JavaScript, modern CSS/component libraries, and client-side data fetching.
• Strong backend skills: building and maintaining production APIs (Python preferred; Node or Go also fine) - routing, auth, validation, and persistence.
• Experience wiring frontend to backend: API design, auth (JWT/OAuth or similar), and debugging full request paths.
• Comfortable with SQL and at least one relational database; able to model simple schemas and write efficient queries.
• Working knowledge of Git, pull request workflows, and CI/CD for web apps and APIs.
• Clear written communication - PR descriptions, API notes, and design trade-offs.

Preferred Qualifications

• Next.js App Router, React Server Components, and/or MUI (or similar design systems).
• Prisma, SQLAlchemy, or equivalent ORM experience.
• Go for services/gateways, or prior work with API gateways and JWT/Redis auth patterns.
• GCP and/or AWS application development (Cloud Run, GKE, S3/GCS, Secrets Manager).
• Experience with data-heavy or AI-assisted products (search UIs, dashboards, inference APIs).
• Prior work in SOC 2 or similarly controlled environments.
