Now led by a CTO WHO is ex-Palantir, this well-funded team is building a next-gen B2B platform that’s set to revolutionise subscription technology. Their mission? Help businesses deeply understand their customers, not just rely on one-size-fits-all tools.

Early team opportunity: Join as they enter a major growth phase and shape the future of the platform.

Tech-forward environment: Build scalable, event-driven systems using cutting-edge tools.

?️ Tech Stack & What They’re Looking For:

Strong hands-on experience with React and TypeScript but other stacks will be considered

Deep familiarity with AWS (Lambda, DynamoDB, SQS, SNS, ECS)

Proven ability to take product requirements and deliver production-ready systems

Background in event-driven architecture and RESTful API design

? Location:

London (Hybrid flexibility available)

If you’re passionate about building high-impact systems and want to be part of a mission-driven, product-focused team, we’d love to hear from you.
