Job description

Attio is on a mission to redefine CRM for the AI era.

We’re building the first AI-native CRM — designed for the most ambitious go-to-market teams. We recently announced our $52M Series B, led by GV (Google Ventures), with support from Redpoint, Balderton, Point Nine, and 01A. Our team thrives on solving complex technical challenges, delighting our users, and setting a new standard for the industry.

About the role

Our Engineering team tackles the toughest challenges, so our users never have to. Real-time infrastructure, AI-native architecture, and a frontend that feels effortless - all powered by a team that moves fast, thinks rigorously, and holds an exceptionally high bar for quality.

We’re looking for a Senior Product Engineer who takes pride in pushing boundaries, obsesses over details, and wants to help reinvent how millions of people work.

What you’ll do

• Use your strong expertise in TypeScript/Node.js/GCP to move the company and product forward
• Lead projects end-to-end to solve real customer problems
• Architect the systems which power new features to support our high standards of performance, reliability, security and scale, and re-architect existing systems as their scaling demands grow
• Design REST API contracts for both internal and external consumers that are easy to work with
• Represent Attio’s Product & Engineering values both internally and externally

What you’ll bring

• Experience designing scalable, reliable, secure backend systems
• Excellent knowledge of modern Cloud Native systems architecture
• Expertise with Node.js and TypeScript
• A track record of ownership and product delivery
• A proactive, self‑motivated problem solving attitude, with a strong passion for advancing and innovating in distributed systems
• The ability to communicate technical ideas to the wider team and influence stakeholders across Engineering, Product and Design

Nice to have:

• Experience contributing to, or participating in open source projects
• An interest or experience in mentoring other members of the team
• Experience working with data-rich backend applications, or processing large volumes of real-time data
• A love for experimenting with new ideas, tools and techniques, and exploring new technologies

What we offer

• Competitive salary of £95,000 to £125,000
• Equity in an early‑stage tech company on an incredible trajectory
• 25 days holiday plus local public holidays
• Apple hardware
• Private medical insurance through AXA
• Pension contribution through Hargreaves Lansdown
• Enhanced family leave
• Team off‑site in fun places! (We've been to Barcelona, Lisbon, Malta, and Split so far)
