An opportunity to join one of the most exciting early-stage AI companies operating at the intersection of enterprise SaaS, data, and corporate travel. The client is the AI-powered Mission Control for Corporate Travel — enabling global enterprises to manage $50M–$1B travel budgets with real-time data, accountability, and cost optimisation.
Backed by Series A funding and signing enterprise contracts bi-weekly (mid-to-high six figures on 3-year deals), this is a rare opportunity to join at just 25 employees — right at the inflection point of serious scale.
The Why? (Top 3 Reasons to Join)
- Massive Impact at the Perfect Time: With just 25 employees split between Europe and the US, you’ll join at a stage where every line of code materially impacts enterprise customers managing over $4B in spend. Trusted by world-leading companies representing over $4T in market value. Contracts are closing every two weeks. Product-market fit is proven — now it’s about scale. You’ll own features end-to-end and demo your work to the entire company every Friday. Your contributions will be visible, valued, and directly tied to growth.
The What..
The client is looking for a Senior Software Engineer (4–7 years’ experience) to join their founding engineering team. This is for builders. People who thrive in ambiguity. People who enjoy shipping fast. People who want ownership, not tickets. You’ll design, build, and deploy full-stack features across:
- Frontend
- Infrastructure
You’ll work closely with product and leadership to scale a high-performance B2B SaaS platform supporting enterprise clients across travel, fintech, and global corporates.
What They’re Looking For
