About this Vacancy
PE Limited is seeking an experience Software Engineer to join its Innovation team — a forward-looking group within the wider Development and AI Engineering team focused on developing next-generation capabilities across a variety of technologies from AI to digital twins.
This role is ideal for a strong software engineer who enjoys collaborating with scientists and researchers, and who excels at transforming early-stage prototypes into reliable, scalable, and maintainable software systems. This is not a research role that includes some coding. It is a software engineering role at the frontier of innovation — ideal for software engineers who enjoy turning new ideas into reliable, working systems that make an impact.
You will:
- Take ownership of maturing research prototypes into robust, production-grade software.
- Translate fast-moving exploratory code (e.g., in Python, Julia, R) into performant, tested implementations using compiled languages such as C++, C#, Fortran, or others suited to production needs.
- Contribute to the early-stage exploration of technologies such as AI/ML/RL, optimization, digital twins, control systems, agent-based systems, and probabilistic programming.
- Partner closely with researchers, domain scientists, and engineering teams to identify technically promising ideas and build high-quality software around them.
- Help ensure that research outcomes are production-ready by integrating testing, documentation, and code quality standards early in the pipeline.
- Participate in cross-functional design, implementation, testing, and deployment of our software toolkits.
Qualifications
-
An advanced degree (Master’s, PhD, or equivalent experience) in a technical field such as Physical Sciences, Engineering, Geoscience, Mathematics, or Computer Science.
-
Strong professional experience as a software engineer, ideally in production environments involving scientific or technical software.
-
Expertise in one or more production-grade compiled languages (e.g., C++, C#, Fortran), with the ability to write high-performance, maintainable, and scalable code. Familiarity with high-level languages (e.g., Python, Julia) is beneficial for working with research prototypes but is not the primary focus.
-
A solid foundation in software engineering principles, with a focus on modular design, testing, documentation and maintainability.
-
Strong communication skills and experience collaborating across research and engineering teams.
-
Organised, proactive, and comfortable operating in a fast-paced, exploratory environment.
Additional technical competency across a selection of the following disciplines may be beneficial:
- Experience with scientific computing, numerical methods, or computational modelling.
- Familiarity with emerging and interdisciplinary technologies such as: machine learning, digital twins, agentic systems, reinforcement learning, probabilistic computing, or control systems.
- Experience working in or alongside an applied R&D or innovation-focused team.
Package
We offer an exceptional package which includes salary, performance related bonuses, other benefits and relocation assistance (where applicable). The company encourages and structures its salary based on personal performance and contribution to the success of others.
