Senior Software Engineer

🚀 Senior Software Engineer – London (Hybrid)

Join a small, elite engineering team building category-defining SaaS for one of the world’s most high-stakes industries.

We’re a fast-growing London startup founded by industry veterans who saw firsthand how outdated, manual and chaotic private-market workflows still are. We’re fixing that. Our platform sits where SaaS, fintech and legaltech meet — reshaping how sophisticated investment teams collaborate, automate and execute deals.

Our first product launched in 2023 and is already used by leading names in the sector. Now we’re expanding our team to deliver a multi-product roadmap and ship the next wave of innovation.
