About us
We're an early-stage startup building a multi-tenant SaaS platform for regulated and public-sector customers.
The role
We're building a multi-tenant platform on Google Cloud, and we need a senior full-stack engineer who can own features end-to-end—from the React UI, through tenant-aware Fastify APIs, down to the Postgres data model—and who helps harden the foundations as we grow: tenant isolation, test coverage, and our CI/CD safety net. You'll join a small, high-ownership team where your architectural decisions stick. Compliance is part of the landscape here (audit trails, access controls, regulated customers), so you'll build with that in mind—but this is a broad full-stack role, not a single-domain specialty.
What you\'ll do
Build features end to end—Postgres schema and Prisma models, Fastify APIs, and the React UI that consumes them.
Design and evolve ourmulti-tenantdata model and access controls (Postgres RLS, role-based permissions) with isolation we won\'t regret in two years.
UseZodand strong typing throughout to keep API contracts and runtime validation honest.
Own features through to production on Google Cloud Run, including observability and debugging in a live environment.
Raise the quality bar: grow automated test coverage (Vitest, Playwright) and wire quality gates into CI/CD.
Review PRs, mentor, and help set technical direction as the team grows.
Bring a modern approach to end-to-end testing.
Be comfortable with AI-assisted development and help build out agents to increase team productivity.
What you bring
6+ yearsbuilding production web applications full-stack, with meaningful time as a senior or staff engineer.
StrongTypeScriptacross both front end and back end—equally at home in a React component and a backend service.
SolidReact(hooks, modern patterns) with a fast build toolchain (Viteor equivalent).
Server-sideNode.jswithFastify, Express, NestJS, or similar—API design and architecture.
StrongPostgreSQLand data-modeling instincts, plus an ORM (Prismaideal) and migrations at scale.
A feel for multi-tenant data isolation—row-level security, tenant-scoped access, the common footguns.
Good judgment on trade-offs: schema-per-tenant vs. row-level isolation, build vs. buy, where to draw the line on abstractions.
Comfort withDockerfor local development.
Clear communicator who writes things down.
Nice to have
FedRAMPor equivalent regulated experience (FedRAMP Moderate/High, DoD IL4+, NIST 800-53)—and a working sense of what those controls mean for how you write code.
PostgreSQLdepth—RLS and multi-tenant patterns.
Multi-tenant identity depth—OIDC, SAML, SSO, MFA, session handling (helpful, not the focus of the role).
Tailwind CSS, TanStack Query / React Query, Firebase / Google Identity Platformauth.
Google Cloud(Cloud Run, Cloud Storage) and GitLab CI/CD.
Background in compliance, GovCon, or other regulated/document-heavy domains.
