Senior Full Stack Developer - AI & Data

Job Overview

We're hiring a Senior Full Stack Developer who works across backend engineering, data infrastructure, applied LLM systems, and SEO-optimized web builds. You'll build the APIs, pipelines, websites and dashboards that power our internal tools and client delivery - owning features end to end, from database migration to UI.

Comfort with AI coding tools and LLM APIs is essential, not optional. It's how we ship.

Key Responsibilities

Backend & APIs

- Build scalable services in Python (FastAPI/Django), containerized with Docker.
- Design REST APIs, including long-running jobs with streaming progress.
- Build dashboards and internal UIs in React, Next.js and TypeScript.

Cloud Infrastructure (GCP)

- Deploy and operate containerized services on Cloud Run - revisions, scaling, concurrency, cold starts, secrets.
- Manage Cloud Storage buckets for assets, reports and backups, with sane lifecycle and access policies.
- Provision and maintain Compute Engine VMs for long-running or non-containerized workloads.
- Set up recurring pipelines with Cloud Scheduler and job queues.
- Work with Secret Manager, IAM roles and service accounts, Artifact Registry, and Cloud Logging/Monitoring for debugging production.

Data Handling at Scale

- Ingest, clean and normalize large structured and unstructured datasets - CSVs, scraped web content, transcripts, PDFs, third-party API exports.
- Build extraction and enrichment pipelines that turn messy raw input into queryable, deduplicated records.
- Handle the unglamorous parts properly: entity resolution, canonical naming, missing and conflicting values, validation gates before data reaches a client.




- Keep pipelines resumable and auditable so a failed run can be traced and re-run, not restarted from zero.

SEO-Optimized Website Building

- Build fast, technically clean marketing sites in Next.js with a headless CMS (Payload).
- Own technical SEO: structured data (JSON-LD), sitemaps and robots, canonicals, metadata, internal linking.
- Optimize Core Web Vitals, rendering strategy and crawlability.
- Build for AI search visibility, not just Google rankings.

Databases

- Design and normalize PostgreSQL/Supabase schemas; write migrations by hand.
- Implement RLS, backups and access controls.
- Optimize queries and connection handling under concurrent load.

LLM Engineering

- Work across multiple providers through a unified gateway.
- Build structured-output flows, RAG and retrieval pipelines, and agentic workflows.
- Optimize cost and latency: prompt caching, model routing, token accounting.
- Treat hallucination as an engineering problem - build validation and evals, not vibes.

AI Coding Tools

- Daily, skilled use of Claude Code, Codex, Cursor or similar. Decompose tasks well, review output critically, and know when to write it yourself.
- Never ship generated code you can't explain.

Internal Team Enablement & Automation

- Sit with non-technical teams, map how they actually work, and find the manual steps worth automating.




- Turn those workflows into tools the team can run themselves - no engineer in the loop for routine runs.
- Write clear internal docs and walk teams through new tools; support and iterate after launch.
- Measure what you automated: time saved, errors avoided, throughput gained.

Integrations & Automation

- Integrate third-party APIs with rate limiting and failure isolation.
- Handle OAuth, JWT and service-to-service auth; manage SDK version drift.
- Automate manual workflows end to end - ingestion through to insight delivery.

Reporting & Analytics

- Build automated dashboards and client-facing PDF/HTML reports.
- Translate business goals into metrics and KPIs; investigate trends and anomalies.

Testing & Debugging

- Write real tests (pytest, Playwright, Vitest), including deterministic mocks for LLM code.
- Debug across the stack - job state, silent failures, provider timeouts, concurrency. Root-cause it.

Requirements

- 4+ years shipping production full-stack applications.
- Solid Python and PostgreSQL; solid React/Next.js/TypeScript.
- Hands-on GCP experience - Cloud Run, Cloud Storage, Compute Engine, Cloud Scheduler.
- Experience working with large, messy datasets - cleaning, normalizing and making them usable.
- Production experience with LLM APIs - RAG, structured outputs, cost optimization.
- Hands-on technical SEO experience on sites you've built and shipped.
- Fluent, critical use of AI coding assistants.
- Docker, Git, and a genuine testing habit.
- Comfortable working directly with non-technical teams.

Nice to have: pgvector/embeddings, Supabase, headless CMS (Payload/Sanity), marketing-analytics background.
