About Biomatter

Biomatter designs enzymes that never existed in nature - proteins that were, until recently, impossible to create. They're already at work in health, food, agriculture, and sustainable manufacturing: companies like BASF, Thermo Fisher, and Kirin build their products on enzymes we designed.

Behind this is our platform, which combines state-of-the-art AI with our own wet laboratory. Algorithms design new proteins, the lab builds and tests them, and every experiment makes the next design better. That's why our team spans software engineers, AI researchers, and scientists at the bench.

The role

• Recruiting directly in the early months, using external support where it makes sense, and building an internal team if volume later justifies it

• Supporting the full employee lifecycle, including recruitment, onboarding, development, engagement, and offboarding;

• Designing and executing people strategy and frameworks that actually get implemented

• Coaching managers on people and performance questions, helping them act rather than acting for them

• Building the performance management infrastructure: systems that help the company know when to invest in someone and when to move on

• Shaping and protecting culture as the company scales

• Being a clear, senior People voice in the exec team, proactively co-developing the HR function with the CEO

What we are looking for

Essential: you've built a People function before, starting small. You joined a company early and grew with it, from a handful of people to well over a hundred.

You have genuine care for people and know how to create the systems to enable them. You know how to keep high performers challenged and engaged. You spot underperformance early and help managers act on it, with the right tools. You're comfortable in a room with senior leaders and not afraid to push back or name a difficult truth.

One thing worth flagging: this is a team of scientists, engineers, and lab professionals. Experience working in a similar environment is a genuine advantage here.

Useful but not essential: comfort with occasional international hiring; having built leveling frameworks and pay bands from scratch.

What we offer

• 3,000–4,000 EUR net per month, Vilnius.

• Private health insurance after probation period
