## Job description

## 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.

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 (45-60 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.

## Equal Opportunities and Accommodations Statement

At Magentic, our mission is to build AI that helps solve some of the world's most complex real world problems. We believe building a diverse workforce will be the key to solving this for our customers.

Magentic is committed to creating a truly inclusive team and we’re proud to be an equal-opportunity employer. As we grow, we're intentional about building teams with a broad range of backgrounds, experiences and viewpoints, recognising that this leads to better ideas, stronger collaboration and better outcomes for our customers therefore we strongly encourage applications from all backgrounds and cultures to apply.

We recognise that some groups remain underrepresented within the industry and are committed to creating an environment that celebrates and supports everyone.

Everyone works differently, and we want to ensure our interview process gives you the best chance to show us what you can do. If you require any reasonable adjustments or accommodations, please let us know and we'll work with you to make the process accessible.

Responsible AI Statement At Magentic, we are committed to developing artificial intelligence that benefits humanity.

## About Magentic

## Company Overview
- **One-liner**: Magentic provides an enterprise-grade AI agent platform that deploys autonomous "Mage" digital workers into supply chain and procurement teams to capture P&L savings.
- **Entity Type**: Private (Seed/Series A funded)
- **Headquarters**: New York, New York, United States
- **Founded**: 2024
- **Founders**: Robin Van Aeken (Co‑Founder & CEO), Odhran O'Donoghue (Co‑Founder & CTO)

## Core Business
- **Primary industry/industries**: Supply Chain & Procurement Technology (AI Agents)
- **Target customers**: Global manufacturers, large enterprises with complex procurement and supply chain operations (B2B, Enterprise)
- **Mission or purpose statement**: "Supply chains are the hidden engines of our world… we build a technology that doesn’t keep up, it stays ahead." — inspired by the medication shortage crisis.

## Products & Services
- **Mage AI Teammates**: Autonomous digital workers that embed into procurement teams. They use existing company software (ERPs, email, files), search data, manage thousands of documents, and execute actions like updating invoices, notifying suppliers, and preparing price negotiations. **Type**: AI Agent Platform (SaaS + embedded digital workers)
- **Mage Internship / Full‑time / BAU Models**: Flexible deployment stages — start with an internship to prove savings, move to full‑time qualification, then continuous business‑as‑usual operation across the spend base.
- **No‑cure‑no‑pay pricing**: Customers pay based on measurable value delivered, typically within weeks.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: **$5.5M total funding** (Seed/Series A round, August 2025, led by Sequoia Capital)
- **Notable Investors/Partners**: Sequoia Capital (lead), plus three other institutional investors. Partners not explicitly named but integrates with major ERP systems (SAP, Oracle, Coupa).
- **Growth Signals**:
  - Headcount: 16 employees (as of mid‑2026), with +6.2% monthly growth.
  - 11 active job postings (57% monthly increase), indicating rapid scaling.
  - Case studies show quantifiable savings: 4% on MRO spend at a $40B manufacturer; 25% supplier document error rate reduction at a Fortune 500 company.
  - Clients include global manufacturers with >$40B revenue.

## Competitive Advantages
- **Deep domain focus**: Built specifically for procurement and supply chain workflows, not a generic AI chatbot — mages are trained on company policies, processes, and ERP data.
- **Human‑in‑the‑loop safety**: All actions are deterministic, auditable, and require human approval at key decision points; SOC 2, ISO 27001, GDPR compliant.
- **Lightning‑fast onboarding**: Integrates with any data store and ERP in days, not months.
- **Outcome‑based pricing**: Low risk for customers (no‑cure‑no‑pay) — the company is incentivized to deliver real P&L value.

## Strategic Focus
- **Scale the Go‑to‑Market**: Build on early enterprise wins and expand customer base among global manufacturers.
- **Platform expansion**: Deepen integration capabilities with more ERPs and supply chain systems, and extend Mages to additional procurement sub‑domains (e.g., supplier risk, sustainability compliance).
- **Talent acquisition**: Aggressively hiring across engineering, product, data science, and go‑to‑market roles to support growth.

## Why Work Here
- **Culture**: A mission‑driven team (“We started Magentic when the world ran out of medications…”) focused on solving real‑world supply chain fragility. Small, fast‑paced startup (16 people) with a flat structure and high ownership.
- **Remote/Hybrid/Office**: Headquarters in New York, with team members in the UK, Spain, and France. Multiple job postings do not specify location; likely remote‑friendly for technical roles (Forward Deployed Engineer, Data Scientist).
- **Notable perks / engineering culture**: The tech stack is modern (Python, TypeScript, React, Kubernetes, Snowflake, dbt). Engineering team includes alumni from Celonis, Revolut, McKinsey, Dynamo AI. Employees are given the autonomy to shape the product from the ground up.
- **Career growth**: As an early‑stage company backed by Sequoia, employees have significant impact on product and company direction. The rapid headcount and job posting growth suggest strong upward mobility.
