Full-time
The Role
We’re looking for a Staff Machine Learning Engineer who thrives at the intersection of software engineering and applied ML. This role is ideal for engineers who enjoy building real products — not just models — and want to take machine learning systems all the way from data to production. You’ll own the full lifecycle of ML-powered applications: designing data pipelines, building training workflows, integrating models into services, and deploying production-ready features that power delightful user experiences.
You’ll help us test new ideas quickly, by working in lean, build-measure-learn cycles. You’ll develop rapid prototypes, test them on real users, and iterate based on learnings and user-feedback.
No hands-on AI/ML experience, no problem! Do you excel at solving end-to-end software problems but don’t have hands-on experience with AI/ML? Do you have a computer science, statistics or other relevant STEM background? If so we'd love for you to learn the ML part on the job.
You’ll work in London, with 3 days per week from our office and 2 days per week from home.
What You’ll Own
  • You’ll implement, test, and scale a wide variety of ML and AI capabilities, leveraging both established tools and emerging technologies;
  • You’ll own the end-to-end development cycle of ML-powered features, including assessing the impact through means of experimentation
  • You’ll collaborate with other cross-functional teams to integrate ML solutions into our products;
  • You’ll monitor, evaluate, and improve the performance of models and ML-powered features in production;
  • You’ll stay up-to-date with the latest developments in ML and AI, to ensure we’re always operating at the cutting-edge;
Who We’re Looking For
  • Strong software engineering background with experience in building and maintaining production systems.
  • Hands-on experience with machine learning frameworks (e.g., PyTorch, TensorFlow, scikit-learn) and MLOps tools (e.g., Airflow, MLflow, Vertex AI, or similar).
  • Solid understanding of data engineering practices, including ETL, batch/streaming pipelines, and data quality monitoring.
  • Familiarity with cloud infrastructure (AWS, GCP, Azure) and containerization.
  • You have experience with shortening “build-measure-learn” by means of prototyping and experimentation to iterate quickly and build software users love.
Linktree is committed to providing a fair and competitive compensation package including cash, equity, and benefits. The base salary offered for this role is targeted at $100,000-$130,000 GBP for roles based in United Kingdom. Final offers depend on multiple factors including location, experience, expertise, and role scope, and may vary from the range listed.
P.S. If you don’t tick every box in this listing, please don’t rule yourself out. We take pride in inclusion and hiring incredible human beings with great potential over ticking boxes – so if this role resonates with you, hit that apply button!
