- Be the go-to person for employees on all people-related matters, especially day to day processes and questions
- Support leadership with workforce planning, compensation, and performance processes
- Ensure legal and compliance requirements are met across our international offices (Houston, Singapore, Krakow, and London)
You offer:
- Experience working in People/HR roles at high-growth startups (ideally VC-backed), reporting into a VP or Head of People
- Strong operational capability and confidence in building and improving HR processes from scratch
- Hands-on experience with Bob (preferred) or other modern HR systems (e.g., HiBob, BambooHR, Personio)
- Understanding of UK employment law; international experience (e.g., Poland, US, Singapore) a plus
- A people-first, detail-oriented mindset with strong interpersonal and communication skills
- Comfortable operating autonomously in a fast-paced, evolving environment
We offer:
- Salary starting at £70k (depending on experience)
