Narwhal Labs 🐋
Senior Backend Developer
Bristol (Hybrid)
The AI communications space is moving fast. We need an engineer who can move faster. 🚀
At Narwhal Labs, we're building intelligent systems that are changing how businesses communicate and we're looking for a Senior Backend Engineer to help us architect what comes next.
This is a role with real weight. You'll be designing and scaling the backend infrastructure that powers our AI platform, integrating cutting-edge LLMs and ML services into production, and acting as a technical anchor for a team of junior engineers who are looking to grow.
If you've ever wanted a role where your architectural decisions actually matter, this is it.
The role
You'll work primarily in Python, however you can expect a mix of:
* Designing and building scalable APIs and microservices
* Integrating AI/ML features and LLM-powered services into live products
* Contributing to platform architecture and long-term technical roadmap
* Mentoring junior developers through code reviews, pair programming, and real coaching
* Collaborating with product, design, and AI specialists to ship things that matter
What we're looking for
* 5+ years of backend experience with strong Python skills (plus previous experience with the likes of .NET/C# and PHP)
* Solid grasp of RESTful APIs, microservices, authentication, and database design
* Cloud platform experience — AWS, Azure, or GCP
* Hands-on exposure to AI/ML frameworks or LLM API integrations
* A natural mentor who gets as much satisfaction from growing people as shipping code
* Strong communicator who thrives in a collaborative, fast-paced environment
Bonus: Docker/Kubernetes, CI/CD pipelines, MLOps, distributed systems, or frontend exposure (Next.js, React, TypeScript)
What you'll get
* Competitive, benchmarked compensation
* Real ownership of architecture, decisions, and your own career trajectory
* A front-row seat to the AI revolution, working with tools and problems most engineers don't get near
* A collaborative team that takes engineering quality seriously
We're building something ambitious. We'd love to build it with you.
