Careers

Build useful software with us

We’re a small, senior team in London building software, agentic AI and web portals for UK organisations. We value clear writing, pragmatic engineering and shipping value in weeks, not months. If you care about quality, impact and kindness, you’ll fit in.

Why Primepath

  • Meaningful work with UK clients across fintech, health, public sector and retail.
  • Calm delivery culture: small teams, weekly demos, no heroics.
  • Modern stack (TypeScript, Python, Go, AWS/Azure, Terraform) with strong engineering practices.
Benefits

What we offer

  • Competitive salary aligned to market and experience.
  • Hybrid working with a London hub near Covent Garden.
  • 25 days holiday + public holidays.
  • Learning budget and time for conferences, courses and books.
  • Quality tools: choice of laptop, top-tier editor/IDE licences.
  • Inclusive, respectful culture with clear feedback and mentoring.

How we work

We favour small, cross‑functional teams with tight feedback loops. Discovery is time‑boxed. Architecture is sketched before code. We write tests and instrument apps early so change is safe. Accessibility and security are not afterthoughts — they’re baked in.

Senior Python Developer

8+ years experience
London (Hybrid) • Full‑time • Team: Engineering

About the role

You’ll lead delivery of Python‑based services and data/AI integrations across client projects. You’ll work closely with product, design and platform engineers to design clean APIs, implement robust business logic, and ship reliable software to production. We value engineers who keep things simple, write clear docs and care about outcomes.

What you’ll do

  • Design and build services using FastAPI or Flask, Pydantic models and async I/O where appropriate.
  • Integrate with third‑party APIs, queues and databases (PostgreSQL, Redis).
  • Collaborate on architecture, data flows and security controls with the team.
  • Write tests (pytest), add logging/metrics/traces, and automate deploys (CI/CD).
  • Contribute to AI workstreams (RAG pipelines, tool‑calling agents) with Python.
  • Mentor teammates, review PRs, and help improve our engineering practices.

What we’re looking for

  • 8+ years building production software with Python.
  • Strong experience with FastAPI/Flask, SQLAlchemy/psycopg and async patterns.
  • Solid understanding of HTTP, REST, OAuth/OpenID Connect and web security basics.
  • Working knowledge of cloud (AWS or Azure) and infrastructure as code (Terraform).
  • Familiarity with containerisation (Docker) and CI/CD.
  • Bonus: experience with data processing (Pandas), vector stores, or orchestration tools (Celery, Airflow).

Nice to have

  • Experience building or integrating agentic AI components, prompt design and evaluation.
  • Observability mindset (OpenTelemetry) and performance tuning.
  • Exposure to TypeScript/Node or Go in multi‑language environments.

Interview process

  1. Intro call (30 min): background, interests, Q&A.
  2. Technical chat (60 min): architecture discussion + API design exercise.
  3. Practical task (take‑home or pair, your choice): realistic, time‑bounded.
  4. Final (45 min): values, ways of working, offer questions.
