We bring together state-of-the art machine learning know-how with domain-specific expertise from industry partners to accompany our customers through successful AI implementation. We work across domains, including manufacturing, pharmaceutical, healthcare, public sector, and many more. Our start-up DNA defines the way we drive fast and sustainable value creation, embracing a culture of rapid iteration to build scalable solutions.

We are looking for a People Lead to own and evolve our people function end-to-end. This is a generalist role with real scope: you will work closely with leadership and managers across the company, shaping how we hire, develop, retain, and support a high-performing team in a fast-growing AI consultancy.

You will be the go-to person for everything people-related, from building hiring pipelines and running performance cycles to designing culture initiatives and coaching managers. If you thrive in environments where you can take something solid and scale it, with real autonomy and visible impact, this role is for you.

These will be your main responsibilities:

• Own end-to-end recruiting across multiple roles simultaneously, including sourcing, structured interviews, offers, and headcount planning with Manager Director;

• Lead the strategy for the People Area, overseeing the execution carried out by the relevant people

• Conduct salary benchmarking, analyse the hiring funnel, and report on recruitment KPIs;

• Run full performance review cycles, including calibration sessions, compensation proposals, promotions, and bonus framework design;

• Build and maintain competency frameworks and career progression structures;

• Design and deliver manager training and coaching on performance, feedback, retention, and difficult conversations;

• Create toolkits and templates; facilitate workshops at off-sites and company retreats;

• Lead internal change projects from diagnosis through rollout and impact measurement;

• Own onboarding and offboarding end-to-end;

• Run wellbeing surveys and stay interviews, and translate findings into action;

• Monitor turnover trends and develop targeted retention strategies;

• Build and maintain a People Dashboard tracking key metrics;

• Manage HR tooling, employee lifecycle administration, and people data integrity;

• Ensure compliance with German labour law (GDPR) and handle sensitive cases with discretion;

• 5+ years of experience in a generalist HR or People role, ideally in a startup or scale-up environment

• Strong understanding of tech and AI roles (e.g. data, ML, engineering), with the ability to assess skills and build effective hiring and development frameworks for these profiles

• Proactive in leveraging tools and automation (incl. AI) to scale People processes, improve efficiency, and drive data-informed decision-making

• Demonstrated ability to independently manage the full spectrum of People & Culture functions (e.g. talent acquisition, performance, operations, and employee experience)

• Experience running structured performance review processes, including calibration and salary cycles

• Track record of building and iterating on HR processes from scratch rather than simply inheriting them

• Familiarity with German labour law and compliance requirements.

• Structured and data-driven: you track what matters, build dashboards, and use data to tell a story

• Strong communicator: able to write clearly, present to C-level, and adapt your style for different audiences

• Builder mentality: you enjoy creating new things and are comfortable navigating ambiguity

• High empathy and strong people judgment: you build trust, understand individual needs, and create a supportive environment

• Confident decision-making: you take ownership and make clear, timely decisions independently

• Organised and reliable: when you own something, it gets done properly

• Fluent in English (written and spoken), German is a plus

• Engaging Topics: We work at the cutting edge of real-world AI solution delivery, offering unique insights into applied machine learning research and development.

• Shared passion for excellence: Every member of our team is motivated by doing great work, meaning you have the chance to collaborate with highly talented engineers and entrepreneurs who are experts in their field.

• International Team: We are a dynamic and international team with over 16 nationalities represented at Momentum.

• We offer Visa Sponsorship.

• Learning and Development: We provide an annual learning and development budget for attending conferences or purchasing educational resources to further develop our employees’ skills. We also hold weekly and monthly events around AI innovation and implementation.

• Dynamic and open Working Culture: We have a very flat hierarchy, open 360° feedback, and flexibility in our work-from-home policy as well as working hours.

• AI Ethics: We are committed to developing ethical AI software and actively foster open discussions on this topic within our team.

• One of Europe’s most dynamic AI ecosystems : As part of the Merantix Group, we benefit from being at the heart of the AI Campus in Berlin, which brings together an amazing community from start-ups to investors, established organizations to researchers, and many more.

• Hardware allowance and supplementary work equipment: We give you support to have all the equipment you need to thrive in the job.

• Employee benefits: We offer a monthly allowance per employee that can be allocated as desired to one of the following: Mobility & transportation (Navit), sports (Urban Sports Club) or groceries (Edenred)

We are an equal-opportunity employer and value diversity. We consider all applications equally regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, or gender identity. We strongly encourage individuals from groups traditionally underrepresented in tech to apply, and we can help with immigration.
