Job description

Modelling Software Engineer - Chronos

Department: Tech - Model & Platform Engineering

Employment Type: Permanent - Full Time

Location: Oxford, UK

Description

Chronos is Aurora's battery storage modelling product. It simulates how batteries operate in power markets, and our clients use the results to make investment decisions. Behind it sits a large Python codebase that turns modelling methods into software the whole business can rely on.

We’re looking for a Modelling Software Engineer to help us build and maintain the Python codebase behind Aurora’s Chronos battery storage modelling product. You’ll work in a small team (5-6 people) within a collaborative engineering and product-driven environment, owning feature development end-to-end to deliver valuable outcomes for users, while improving code quality and maintainability.

You will thrive here if you are keen on both best practice software engineering and sophisticated mathematical modelling of energy systems. You might come from a software background and want to work on energy and battery models. You might come from a modelling, science or quantitative background and want to build strong engineering habits. Both sides of the work are critical to success in this role.

Key Responsibilities

• Own feature development end-to-end: requirements, design, implementation, testing, deployment, and live operation.
• Break down and estimate your own work accurately, and deliver to those estimates reliably. Deliver in increments so value is realised early and feedback arrives continuously.
• Actively seek regular review and feedback to improve your own engineering and project delivery practice. Review others' code regularly, giving substantive, constructive feedback to others.
• Identify and champion best practices and processes for software development.
• Write maintainable, robust code. Favour simple solutions over complex ones, and treat operational requirements (logging, scalability, security) as part of the design, not an afterthought.
• Apply agentic development practices in an accountable way to write, review, test, and analyse code, and help shape how the team applies it.
• Actively support your team-mates, driving success and continuous improvement across the team.

Skills, Knowledge and Expertise

• 2–4 years of professional software engineering experience, with a track record of independently owning production software that others depend on.
• Strong fundamentals in testing, clean module design, and maintainable code. Python is the primary language of the codebase.
• A track record of code review, giving and receiving constructive technical feedback.
• Effective project management skills, providing up-front estimates, proactively managing issues as they arise, delivering on time and learning from project outcomes.
• You think about the \"why\" before the \"how\", and you understand what value your work provides to the business and the user.
• Collaborative. You actively work with and support the people around you, and help the squad achieve meaningful goals.
• Experience engaging with internal stakeholders and colleagues in other teams.
• Experience with scientific computing, complex data analysis or computational modelling.
• Willingness to learn (or experience in) effective, efficient and accountable agentic development.
• An interest in working in energy decarbonisation.

What we offer

• Private Medical Insurance
• Dental Insurance
• Parental Support
• Salary-Exchange Pension
