Job Title: Full Stack Engineer (Front-end leaning)

Salary: £110,000–£120,000 + Equity

Company Description: Magentic.com - Sequoia-backed startup building AI agents for the $3tn global manufacturing procurement market.

Job Description:

Join a high-caliber team from OpenAI and NASA to build the user interface for next-generation AI agents. You will own the product experience end-to-end, translating complex procurement workflows into intuitive, polished React applications. This is a high-impact role for an engineer with strong product taste who thrives in fast-paced, early-stage environments.

Location: London, UK

Why this role is remarkable:

• Work at a Sequoia-backed seed-stage startup alongside a world-class founding team with experience from OpenAI, Meta, Revolut, NASA, and McKinsey.
• Solve massive real-world problems by automating $3 trillion in global supply chain workflows using cutting-edge agentic AI systems.
• Enjoy high ownership and autonomy in an environment that values ""Linear-level"" craft, shipping daily, and direct influence over product direction.

What you will do:

• Lead the development of user-facing features using React, TypeScript, and Tailwind, maintaining a robust and scalable design system.
• Bridge the gap between AI capabilities and user needs by designing intuitive interfaces for complex, multi-step agentic workflows.
• Collaborate directly with the founding team and customers to define requirements, prototype solutions, and deploy production-ready code in days.

The ideal candidate:

• Has 6+ years of professional software engineering experience with deep expertise in TypeScript and React, plus proficiency in Python.
• Demonstrates exceptional product intuition and a ""design-first"" mindset, capable of making UI/UX decisions without a dedicated design function.
• Thrives in high-ambiguity, fast-paced startup settings and possesses the right to work in the UK without requiring visa sponsorship.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
