About the team

We're redefining how cars are valued and sold online, and our mission is to make the process as simple and enjoyable as a Sunday drive. We're a tight-knit, data-driven bunch who love tackling complex challenges with innovative solutions. Our work directly impacts thousands of car sellers and dealers daily, ensuring they get the best possible deal. We're looking for a talented Machine Learning Engineer to join our journey and help us build the future of vehicle pricing.

About the role

1. Develop and Deploy Machine Learning Models:You'll design, build, and deploy robust machine learning models that power our vehicle pricing service. Think XGBoost, GPs, and Bayesian models, all running smoothly on GCP and Vertex AI.
2. Build and Maintain Production ML Systems:You'll ensure our backend systems and APIs deliver real-time pricing predictions across all platforms, 24/7. We're talking high-performance, scalability, and stability.
3. Collaborate Effectively:You'll team up with data scientists, analysts, and engineers to solve challenging pricing problems. You'll also partner with our Infrastructure team to align with company-wide best practices.
4. Drive Innovation:You'll be a key player in shaping the future of our pricing architecture. We encourage you to stay curious about emerging technologies (including generative AI) and bring your innovative ideas to the table.

About you

1. ML Experience:You've deployed ML models at scale and have a good understanding of state-of-the-art regression and probabilistic models.
2. Technical Skills:You're proficient in Python (pandas, scikit-learn, fastAPI/flask, pydantic, DVC) and SQL. You also have a strong knowledge of systems design, including serverless and event-driven microservice architecture.
3. Engineering Excellence:You're passionate about writing clean, maintainable code and have strong practices within the context of ML, including OOP, abstraction, error handling, and logging.
4. Cloud and Tools:You're familiar with ML lifecycle tools like Kubeflow and cloud platforms (GCP, Vertex AI, AWS). You also have experience with CI/CD pipelines (e.g., GitHub Actions), Docker, and IaC tools (e.g., Terraform).
5. Testing and Evaluation:You have experience building ML evaluation frameworks and writing tests (unit, integration).
6. Ownership and Collaboration:You have a strong sense of ownership, autonomy, and a highly organised nature. You're also a great team player and communicator.

You could be a great fit if

1. You're proficient in Typescript/JavaScript and Node.js.
2. You're passionate about building and deploying machine learning models that have a real-world impact.
3. You're a creative problem-solver who loves tackling complex challenges.
4. You're a team player who thrives in a collaborative environment.
5. You're excited about the future of vehicle pricing and want to be part of a company that's redefining the used car marketplace.
