Algorithm Engineer (6 months FTC)

Responsibilities

• Design and implement algorithms for forecasting, pricing, and optimisation that can scale across markets and data volumes.
• Lead technical design discussions and guide architectural decisions for high-volume data processing and modelling.
• Translate complex business and energy-market requirements into performant, maintainable, and explainable data solutions.
• Improve the robustness, performance, and scalability of existing models and workflows.
• Mentor peers through code reviews, technical guidance, and knowledge sharing.
• Collaborate closely with Product, Data, and Delivery teams to ensure accuracy, usability, and reliability in production.
• Contribute to Gorilla's growing library of reusable components and frameworks that raise the standard for data and algorithmic excellence.

Requirements

• Proven experience designing, developing, and deploying algorithms or data models (for example forecasting, pricing, or optimisation) in production environments.
• Strong proficiency in Python and experience with the modern data engineering stack such as SQL, Pandas, NumPy, SciPy, Dask, Polars, DuckDB, or PySpark.
• Experience designing, building, maintaining, and evolving microservice architectures and distributed systems.
• Experience working with large-scale or high-frequency datasets such as smart meter, weather, or IoT data.
• Familiarity with SaaS or software product environments; experience in energy or a strong motivation to learn it is a plus.
• A collaborative and pragmatic mindset, comfortable navigating ambiguity, taking ownership, and guiding others toward technical alignment.
• Strong communication skills, with the ability to clearly explain technical concepts to both technical and non-technical audiences.
• Proven experience mentoring and supporting the development of other engineers through code reviews, documentation, and collaborative problem-solving.
• Technical leadership capabilities, including influencing design decisions, promoting best practices, and driving alignment across teams.
• Where and how you'd work
• Our flagship office is in Antwerp, and we also have an office in London and co-working spaces in Reading (UK), Austin (US), and Melbourne (ANZ). If you apply from Germany, this is a remote role, if you apply from the UK or Belgium, it will be hybrid.
• Please note that you must be based in Belgium, the UK, or Germany , as we are not able to consider candidates living in other countries. Occasional travel is required to attend team meetings.
