The Role

We’re looking for a Staff AI Engineer who thrives at the intersection of software engineering, data and AI. This role is ideal for engineers who have experience building real, lovable products leveraging state‑of‑the‑art techniques and modern technologies.. You’ll own the full lifecycle of AI applications: building data pipelines, prompt & feature engineering , integrating models into high throughput, low latency services, and deploying production‑ready , AI powered features that delight our 70+ million users.

What You’ll Own

• Build, deploy, and maintain AI agents and features across Linktree’s core product surfaces — including personalisation, recommendations, and creator analytics
• Partner with Product and Engineering to translate business problems into solutions, driving the roadmap from problem definition through to production
• Design and own scalable data pipelines for feature engineering, model training, evaluation, and real‑time inference
• Establish and uphold engineering best practices for AI: evaluation design, prompt management & versioning, testing & monitoring.
• Lead technical design reviews and mentor engineers on AI foundations and production‑grade AI patterns
• Evaluate and adopt new AI techniques, frameworks, and tooling to keep Linktree at the frontier of applied AI.

Who We’re Looking For

• 6+ years engineering experience with experience in building and maintaining data intensive, production systems.
• Familiarity with modern AI engineering techniques such as prompt‑engineering, fine‑tuning, eval loops, and technologies such as Gemini, Claude and OpenAI APIs.
• Hands‑on experience with AI tools/frameworks (e.g., Braintrust, AutoEval) and/or 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 (we use AWS) and containerization.
• You have experience with shortening “build‑measure‑learn” by means of prototyping and experimentation to iterate quickly and build software users love.

Where and How We Work

We're a global, diverse team spread across continents with offices in London, Los Angeles, Melbourne, and San Francisco. We work together flexibly and you can choose the setup that works best for you: fully remote or a hybrid mix of office and home.

We offer autonomy in how you structure your days and weeks. While we’re mindful of time zones and occasionally collaborate outside the typical 9–5, we lean into async work to keep things flowing. Our culture is family‑friendly and Zoom‑casual where kids, pets, and delivery drivers are welcome.

How we’ll help you thrive

Our approach to benefits considers the whole person and the unique contributions they bring to Linktree. We want the experience at Linktree to be one that enables people to truly thrive so we can Go Further Together (one of our values). Some ways we support you:

• An annual wellbeing allowance to use on things like (but not limited to) fitness memberships, development courses, childcare, travel, charitable donations, pet insurance, home office set‑up - the choice is yours!
• Employer contribution towards your retirement.
• Generous time off for vacation, holidays, parental leave, volunteer time, and other categories.
• Employee stock option program - we want each and every employee to share in the company’s success.
