About the Role

We are looking for a full‐stack Senior Software Engineer to work in our Customer Development team on our ground‐breaking Frontier platform. Your role will focus on scaling our Decision Intelligence offering – providing AI capabilities across high‐impact decisions. This comes with genuinely interesting technical challenges, with huge space for creativity and influence. We are actively seeking a senior full‐stack engineer to deliver our cutting‐edge product, Frontier, to new clients. As we continue to expand our platform's reach, you will have the unique opportunity to build a scalable AI‐focused product, remain close to live customer feedback whilst leading the way in technical best practices.

In this role, you will be immersed in hands‐on work, tackling complex real‐world challenges using state‐of‐the‐art technology. From optimising multinational supply‐chain logistics to reducing time‐to‐market for clinical trials and supporting sustainability goals in various industries, Frontier empowers organisations to make informed decisions through AI‐driven insights. Join us on this exciting journey of transforming decision‐making with AI and machine learning, revolutionising how businesses thrive utilising Decision Intelligence.

What you will be doing:

At the heart of Decision Intelligence for each customer lies one or more Computational Twins (CT). A CT is a digital representation of an existing business process in which decisions are made. Our platform enables a CT to show historical process performance, model future behaviour and simulate decisions. As a Senior Full Stack Engineer in the Customer Development team, you will lead the technical delivery of customer‐facing projects, working as part of small, cross‐functional teams. You will collaborate directly with customers and their engineering teams to understand their systems and data, and help integrate Frontier into their workflows. This often includes extending or adapting our frontend, backend, and infrastructure‐as‐code components, as well as supporting the creation of Computational Twins that model complex real‐world systems. You will play a hands‐on role in shaping how Frontier is deployed and scaled in production environments, ensuring it delivers real impact from day one.

Your responsibilities will include:

• Serve as a strong technical contributor within a cross‐functional Delivery Squad, working alongside Engineers, Product Designers, Data Scientists, and a Delivery Manager to deliver impactful customer solutions.
• Mentor and support the growth of more junior engineers in the team.
• Collaborate across the wider Frontier engineering organisation to implement new features, resolve issues, and improve the product's user experience.
• Build and extend the product using one or more of our primary languages – Python & TypeScript. Experience with Infrastructure as Code and Rust are also useful.
• Work directly with customer stakeholders, including end users and engineering teams, to integrate Frontier into existing systems, data sources, and workflows.

What we are looking for:

• Full‐stack engineering experience with Python, Typescript and React.
• Experience with PostgreSQL.
• Knowledge of CI/CD pipelines (ideally with GitLab).
• Strong understanding of system architecture and design.
• Experience championing automated testing strategies across various levels of the test pyramid.
• Experience working with cross‐functional teams of engineers.
• Experience collaborating with Product Managers and Product Designers to ensure delightful customer experiences.
• Expertise in Docker with deployment on Kubernetes, preferred.
• An understanding of the AI value chain.
• Experience with startup‐centric fast‐paced work, sometimes introducing creative approaches to difficult problems.

The Faculty team is diverse and distinctive, and we all come from different personal, professional and organisational backgrounds. We all have one thing in common: we are driven by a deep intellectual curiosity that powers us forward each day. Faculty is the professional challenge of a lifetime.
