Back End Developer
Senior Backend Software Engineer - London (Hybrid) Equity + Competitive Salary
Join a fast-growing AI startup transforming a trillion-pound industry through intelligent automation.
We're building the next generation of workflow technology - streamlining complex, manual processes and empowering professionals to focus on the work that truly matters.
If you love solving deep technical problems, shaping architecture, and seeing your code have a real-world impact, this is a chance to build something meaningful from the ground up.
The Role
We're looking for a Senior Backend Engineer to take ownership of key backend services that power our AI-driven platform.
You'll work closely with product, frontend, and AI teams to design, build, and scale backend systems that handle large-scale data, complex workflows, and real-time interactions.
You'll join a small, high-calibre team where your ideas genuinely shape the direction of the product and the company.
What You'll Be Doing
- Architect, design, and build backend applications using Node.js (TypeScript) and NestJS.
- Develop microservices and event-driven systems with asynchronous communication patterns.
- Write clean, maintainable, and well-tested code (unit + integration).
- Design and optimise RESTful APIs with a strong focus on performance, reliability, and security.
- Model and query data efficiently with MongoDB (or similar NoSQL databases).
- Deploy and manage services on Google Cloud Platform (GCP) using CI/CD pipelines (GitHub Actions).
- Troubleshoot and tune performance across distributed systems.
- Collaborate in an agile environment, contributing to design reviews, planning sessions, and team discussions.
What We're Looking For
- 2+ years of professional backend development experience (preferably with Node.js + TypeScript).
- Strong grasp of asynchronous programming, microservices, and event-driven architectures.
- Solid understanding of testing, CI/CD, and cloud deployment workflows.
- Practical experience with MongoDB or similar NoSQL databases.
- Problem-solver with strong communication skills and a collaborative mindset.
- Bonus: experience with message queues (Kafka, RabbitMQ), observability tooling, or DevOps-style environments.
Why You'll Love It Here
- Impact & Ownership - You'll own core backend systems and shape architectural decisions.
- Modern Tech Stack - Node.js, TypeScript, NestJS, MongoDB, GCP, CI/CD.
- Equity + Competitive Salary - Get rewarded for the value you help create.
- Collaborative Culture - Work alongside passionate engineers, product thinkers, and AI specialists.
- Mission-Driven - Help transform a traditional industry through automation and intelligent systems.
- Hybrid Model - Based in London with flexibility to work remotely several days a week.
If you're excited by building elegant systems that make a tangible difference - and want to grow in a fast-moving, high-ownership environment - we'd love to hear from you.
