Back-end Engineer

The Role

We are looking for brilliant engineers to join our team at Magentic. We’re pushing the boundaries of AI with next-generation agentic systems that can manage entire workflows. We’re focusing on a three trillion dollar market of supply chains and procurement.

Our mission is to make global manufacturing supply chains robust to an ever-changing world, and to harness the potential of generative AI through thoughtful deployment, maximising benefits while prioritising ethical use and safety.

You’ll own full-stack features end-to-end, with a focus on building for enterprise data requirements. You will collaborate closely with customer teams to architect and implement sophisticated data pipelines and APIs, directly fueling our cutting-edge agentic AI with terabytes of real-world supply chain data. You will be instrumental in shaping solutions for enterprise clients, all while learning and growing your AI skills in a truly AI-first company at the forefront of agentic systems.

What You’ll Do

• Design & build scalable, performant backend services and data pipelines

• written in Python and deployed with Docker & Kubernetes.

You Might Be a Great Fit if You

• Have 6+ years of professional software-engineering experience.

• Are fluent in Python and comfortable in TypeScript/JavaScript.

• Have built and operated data-intensive systems (batch & streaming) in a cloud environment (AWS, GCP, or Azure).

• Know your way around relational, columnar, and KV/graph databases - and when to use which.

• Have integrated with real-world enterprise stacks - authentication, SSO, legacy ERPs, message queues, ETL tools.

• Can take a loosely defined problem, sketch an architecture, and deliver a production-ready solution in weeks, not months.

• Communicate clearly with both engineers and business stakeholders; you enjoy hopping on a customer call to debug an API contract.

• Thrive in an early-stage, high-ownership environment - prototype today, deploy tomorrow, iterate next week.

Bonus Points

• Experience deploying or consuming LLM-powered services (OpenAI, open-source models, RAG, vector stores) can be a bonus. However, we consider many great candidates without previous AI experience.

• Familiarity with supply-chain, procurement, or manufacturing domains.

Compensation And Benefits
At Magentic, we recognise and reward the talent that drives our success. We offer:

• Competitive Equity: play a real part in Magentic’s upside

• A salary of £125,000 - £140,000 per annum

• Visa sponsorship available

• In-office lunches provided

• Monthly organised socials and an additional flexible monthly social budget for team lunches, coffees, dinners, or activities with colleagues

• Salary sacrifice pension and nursery schemes

• Hybrid London HQ (3-4 days in the office/customer site)

• Annual team retreat - a fully-funded off-site to recharge, bond, and build

Our interview process
We can move quickly through these stages, so let us know if you have any timelines we need to meet.

• Initial call (30 mins): this first step is an opportunity for you to hear more about Magentic and the role, and for us to learn more about how your experience aligns with the role.

• Paired programming interview (45 mins): we'll give you an exercise to demonstrate the key skills for the role.

• In-person interview: for the final step, we invite you to come meet the team in-person and work alongside us! We find this is the best way for candidates to get a sense of what working at Magentic is like. This will include a culture interview, a founder interview and skills-based interview(s) with the team.
