Venture 2

Venture 2 is building the next generation of AI-enabled products. Our work spans one-to-many inference systems with applications in anti-piracy, heavy industry optimisation, and prediction markets. We operate as a hybrid venture studio: developing our own D2C and B2B products while also working closely with partially owned companies through contract-based development.

Following a successful funding round and with a seven-figure contract backlog in place, we are expanding our engineering team. This is an opportunity to join early, gain exposure to cutting-edge systems, and progress rapidly into leadership roles.

We are seeking an ambitious developer at or around the beginning of their professional career. You will contribute to production systems, R&D, and cross-company product delivery. The ideal candidate is motivated to take ownership, learn quickly, and grow with the organisation.

• Experience in data engineering, cybersecurity, prediction systems or financial systems.
