Job description

About us

the company builds the commercial digital twin that large industrial companies run on. We work with global B2B companies to synchronize strategy and execution and ensure commercial success is driven by potential, not gut feel or old data. the company is a category-defining, rapidly growing startup, profitable and majority founder-owned with our Series A still ahead of us, funded by high-profile investors (e.g., Accel) and trusted by 15 global industrial leaders and Fortune 500 customers. Our software integrates complex datasets into a unified solution, combining deep data integration, best-in-class workflows, and cutting-edge generative AI.

The role

Build the core product that every the company client runs on. You take what our Forward Deployed Engineers learn on the ground and turn it into features, tools and agents that work across every deployment. You ship weekly and see real users pick them up.

What you'll do

• Build and ship product features that commercial teams at our clients use every day, from data models to user interfaces
• Turn one-off solutions into reusable product, working with FDEs and Commercial Product Managers on what keeps coming up across clients
• Build front ends, APIs and agents in TypeScript and Python, on Palantir Foundry and our own services
• Own what you ship, including how it's tested, deployed and monitored
• Improve the product by talking to users and watching how features get used

You might be a fit if you

• Have 2+ years building and shipping production software
• Write strong TypeScript (React or similar) and Python
• Care about the user and can turn messy feedback into a clean feature
• Like owning a feature from idea to production rather than one slice of it
• Want to build product at a profitable, fast-growing company where your work is visible

Nice to have

• Palantir Foundry, OSDK or custom widgets
• Data engineering with PySpark or SQL
• Building LLM-powered features or agents
• B2B SaaS or enterprise product experience

Why engineers join us

• Big clients, small team. Some of the biggest names in industry, served by a team of 40. Your work reaches their leadership in weeks, not years.
• Own the stack. We fully control our stack and choose our tools. No committees, no tickets passed between five teams, no egos.
• Built to last. Profitable, founder-led and majority founder-owned, backed by high-profile investors (e.g., Accel), with our Series A still ahead of us. That means growth on our terms and real upside for early joiners.
• Learn from people who've done it. Founders who have run a $1B business, plus people from Palantir, McKinsey and BCG, all in the same room.
• In person, on purpose. Three days a week together in Farringdon. Fast feedback, fast decisions and fast shipping.

What we offer

• Equity through our stock option programme, so you share in the long-term success and growth of the company
• A highly competitive salary
• Direct access to Fortune 500 executives from your first months, at a level most people wait a decade for
• Work alongside former MBB consultants and Fortune 500 executives who will teach you directly — our team is small enough that this happens in person, not through a training curriculum
• Private healthcare
• Pension scheme
• 25 days of annual leave, plus bank holidays
• Work from abroad — up to four weeks a year, and up to two weeks at a time
• Hybrid office policy, with visa sponsorship available
• A company committed to social and environmental responsibility — we pledge to be a net-zero CO₂ company and donate 1% of our revenue to social causes

Practicalities

• London-based, 3 days a week in our Farringdon office
