Remote Senior Full-Stack Engineer — GraphQL/Django Lead

de Anda Capital; Jacksonville (FL); Remote; USD 100,000 - 110,000; Full time

Job summary

de Anda Capital seeks a Senior Full-Stack Engineer to own end-to-end platform slices: GraphQL schema, Django services, migrations, Apollo-driven React UI, and tests on both sides within a spec-driven, agent-assisted workflow.

The backend focus is on correctness, concurrency, multi-tenant isolation, and precise time handling. You will guide coding agents, review PRs, and ensure robust CI/CD and DevOps coordination.

Qualifications

• 3–5 years shipping production web software, with hands-on experience on both fronts: TypeScript/React and Python/Django.
• Designed and consumed GraphQL schemas in production (Graphene or equivalent; Apollo client-side), including codegen and cache behavior.
• PostgreSQL fluency: migrations against live data, composite indexes, constraints, transactions, advisory locks or equivalent concurrency controls.
• Built or maintained background job systems (Celery or equivalent): retries, idempotency, dead-lettering, periodic scheduling.
• Multi-tenant data isolation and role-based authorization as first-class design concerns.
• Correct handling of time: timezones, DST, period boundaries, Decimal hours.
• Has worked with AI coding agents on real deliverables: writes specs an agent can execute, and reviews agent output critically rather than rubber-stamping it.
• Writes tests as part of the change: Jest + Testing Library and pytest + factory-boy.
• Comfortable in Docker Compose, a pnpm/NX monorepo, and GitHub Actions.
• Reads unfamiliar code before writing new code; can cite the existing pattern being followed.

Responsibilities

• Turn refined PRDs into Technical Documents precise enough for a coding agent to implement: schema, service boundaries, data changes, acceptance criteria, and the existing repo pattern to follow.
• Direct coding agents to produce the implementation, then review their PRs line by line against the Technical Document, AGENTS.md, and acceptance criteria before merge.
• Design GraphQL schema the frontend can consume without over-fetching; keep tenant scoping as a first-class argument and index.
• Write and harden service code that holds under concurrency: idempotent enqueue to the calc queue, compare-and-swap on state transitions, Decimal arithmetic for hours and money, timezone-correct pay-period boundaries.
• Add and extend Celery tasks and Beat schedules (dispatch, delivery, reconciliation) that stay testable without a running worker.
• Bring remaining admin screens onto live GraphQL contracts.
• Keep CI honest: regression suite green, no coverage erosion.
• Deploy to dev via GitHub Actions; work with our DevOps engineer on Terraform and the gated prod deploy.
• Triage Sentry across the three apps and the Celery services.
