About YouAs a Full-Stack Engineer at Cyvl, you will play a key role in delivering intuitive, performant, and scalable applications for our customers. You'll be responsible for designing and building across the stack, from elegant, component-driven React interfaces to APIs and services in containerized and serverless environments, backed by relational databases. You'll work in close partnership with product to define and ship features end-to-end, and take real ownership of what you build. The differentiators for us will be a strong technical foundation, a good eye for product, and a genuine enthusiasm for leveraging agents to develop across the stack.
Key Responsibilities- Build across the stack, from component-driven React interfaces to APIs, services, and data layers.
- Design, document, and maintain scalable APIs, and own features end-to-end from conception to deployment.
- Work with containerized and serverless environments and contribute to cloud infrastructure.
- Collaborate with design and product teams to deliver smooth, accessible, and responsive interfaces, and partner with QA and DevOps to ensure robust, testable, and observable systems.
- Participate in architectural discussions and code reviews, and contribute to engineering best practices across the organization.
QualificationsRequired:- 3+ years of professional experience in a full-stack engineering role.
- Experience with React and a modern front-end toolchain (e.g., TanStack Router, Vite, pnpm/Turborepo), with a focus on clean, reusable components and highly interactive, data-driven user experiences.
- Solid understanding of JavaScript/TypeScript and modern front-end development practices (hooks, context, etc.).
- Experience building backend services in Python (e.g., FastAPI) and TypeScript (e.g., Cloudflare Workers, Hono), including designing and consuming RESTful and GraphQL APIs.
- Familiarity with a Postgres-based data layer (e.g., Supabase).
- Solid Git workflow knowledge and experience with CI/CD pipelines (Github Actions), and experience with cloud infrastructure (AWS, Kubernetes, Cloudflare).
- Ability to work cross-functionally in a fast-paced, collaborative team environment.
Nice to Have:- Experience using real user monitoring and analytics tools (e.g., PostHog, Grafana) to make data-driven development decisions.
- Expertise in modern Python development (uv, static type checking, Pydantic, asyncio, pytest).
- Familiarity with event-driven backend architectures using NATS Jetstream.
- Familiarity with geospatial data and tools (e.g., Mapbox, MapillaryJS, PostGIS, map vector tiles, cloud optimized point clouds), and 3D visualization libraries (e.g., Deck.gl).
- Background in data visualization and performance profiling.
- Prior work in early-stage startups or fast-scaling environments.
- Experience writing tests with Vitest, or comparable tools like Jest or Cypress.
- Experience integrating LLM agents or agentic workflows into production web applications.
What We Offer- Comprehensive health, dental, and vision coverage
- 401(k) with immediate vesting
- Generous PTO, paid parental leave, and flexible work options
- Annual professional development stipend
- Team events, referral bonuses, and a collaborative, growth-focused culture
