Full-Stack Product Engineer- Innovative AI Start-Up

Salary: £60 - 80,000 base + substantial stock

Fantastic opportunity for a Product Engineer who thrives on project ownership to join a growing AI-auditing tech firm. Founded in 2023, and backed by some big-name investors, my client has built a trusted platform for safe and responsible deployment of AI systems. Their continuous auditing of AI models ensures transparency, independent oversight and fairness in HR & HR tech. Reporting to the CTO and working collaboratively with product, data & customer-facing teams, this role offers the chance to work across the full stack with a visible impact on product quality, functionality and reliability.
