Senior Frontend Engineer

The Role

We’re looking for a Senior Front-end Engineer who’s excited to shape how people at the world’s largest companies work with AI day to day.

At Magentic, you’ll have a huge amount of ownership over the product experience, building the interfaces through which enterprise users collaborate with AI agents operating in real time. You’ll also play a key role in evolving our frontend technical practices and driving the architecture as we scale.

We’re redefining how people interact with enterprise software. We’re rethinking what great enterprise software looks and feels like, and building intuitive experiences for complex, high-impact workflows.

You’ll be working at the cutting edge of human-computer interaction, helping us define new patterns for how people interact with increasingly intelligent software.

We’re building next-generation agentic systems that can manage entire procurement workflows, with a mission to make global manufacturing supply chains more resilient to an ever-changing world. That’s a $3tn market opportunity.

We’re backed by world-class investors including Sequoia Capital, and you’ll be joining an exceptional team bringing together experience from OpenAI, Meta, Revolut, NASA and McKinsey.

What You'll Do:

- Own the development of high-quality user-facing experiences, from early ideas through to production

- Help drive the architecture and technical direction of our frontend as the product and engineering team scale

- Improve frontend engineering practices, raising the bar for code quality, performance, testing and maintainability

- Work directly with users to understand their problems and make complex AI workflows feel simple and intuitive

- Collaborate closely with Product, Design and Engineering to shape what we build and continually increase the impact of our product

You Might Be a Great Fit if You:

- Have 10+ years of professional software engineering experience, with significant experience building complex frontend applications

- Are highly proficient in TypeScript/JavaScript and React

- Have strong frontend architecture experience and have helped improve technical practices within an engineering team

- Have experience building products powered by LLMs or other AI technologies

- Thrive in an early-stage, high-ownership environment where you can move quickly, influence decisions and communicate effectively across technical and business teams

Bonus Points:

- Comfortable moving between product thinking, interaction design and frontend implementation

- Have experience building or evolving scalable design systems

- Have worked on complex, data-heavy enterprise products

- Familiarity with supply chain, procurement or manufacturing domains

- Comfortable working with Python

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.

- Salary: £120,000 - £135,000 per annum

- Visa sponsorship available

- Hybrid London HQ (3 days in the office).

- Company provided meals at the office

- Monthly “Social budget” to spend getting to know your colleagues (coffee, food, activities, etc.)

- Salary sacrifice pension and nursery schemes

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