Senior Full Stack Engineer | AI-Recruitment SaaS (React & Python)
Location: Peterborough / Hybrid
Salary: £55,000 – £65,000 + Bonus
Tech: React (TS), Python (FastAPI), Google Vertex AI, Postgres, GCP
Build the Future of AI-Driven Recruitment
Are you a Senior Engineer who thrives on "greenfield" projects? Do you want to work on a platform where AI isn't just a buzzword, but the core engine of the product?
Join Crooton to help us build our AI-powered recruitment intelligence platform. We are solving the biggest headache in high-volume hiring: processing thousands of applications with speed, fairness, and intelligence, as well as saving time and money.
This isn't a legacy rescue mission. You’ll be joining a small, senior team to write modern, well-structured code and shape the technical roadmap of a platform that’s already making an impact.
The Tech Stack
You’ll be working with:
- Frontend: React, TypeScript, Vite, Tailwind CSS, Zustand.
- Backend: Python 3.10+ (FastAPI), Postgres, Redis.
- AI/Infrastructure: Google Vertex AI, GCP (Cloud Run), Docker, CI/CD.
What You’ll Be Doing
- End-to-End Ownership: Building and shipping full-stack features, from AI analysis visualisations (Chart.js) to advanced workflows.
- High-Performance UI: Designing complex React components and ensuring our "Command Centre" remains lightning-fast under heavy data loads (AG Grid).
- AI Integration: Refining LLM prompting logic and CV parsing to improve candidate scoring and bias reduction.
- Scaling Architecture: Extending our FastAPI services with a focus on strong typing, validation, and async performance.
Who You Are
We are looking for a "Product Engineer"—someone who cares as much about the user experience as they do about the underlying architecture.
- Frontend Expert: You have deep experience with modern React (Hooks, Composition) and building data-heavy interfaces.
- Python Pro: You are comfortable building and maintaining async APIs (FastAPI/Pydantic).
- Testing Advocate: You believe in the "Testing Pyramid" (Pytest, Vitest, Cypress).
- Problem Solver: You enjoy solving ambiguous, real-world problems and want meaningful ownership rather than just "clearing tickets."
Why Join crooton?
- No Legacy Drag: Work on a modern stack with no inherited technical debt.
- AI-First Culture: We use AI to accelerate our own development and iteration.
- Senior Collaboration: Work closely with our Leadership Team in an environment that values clean architecture and good engineering judgment.
- Real Impact: As part of a small team, you will see your work used immediately by organisations hiring at scale.
- The Package: £55k–£65k DOE + performance-related bonus and a hybrid working model in Peterborough.
