We’re now looking for a Senior Full-stack Developer (Lead) to help us shape the future of PUMA. If you're passionate about building impactful software and want to contribute to a product that drives real environmental change, we’d love to hear from you.

Are you ready to play a pivotal role in shaping PUMA's next chapter? We are seeking a highly skilled Senior Full-stack Developer (Lead) to join our team. This is a fantastic opportunity for a seasoned developer with deep modernization experience: rewriting critical paths where needed, decomposing monoliths into microservices with a SPA front end, scaling the platform (back‑end), and upgrading .NET

Framework to modern .NET (8/9).

As the Senior Full‑Stack Developer (Lead), you bring a proven track record of leading small development teams and successfully managing software projects. You possess the ability to wear a project management hat, effectively engaging with various stakeholders to understand product requirements and features and translate them into exceptional software solutions. Strong preference will be given to those with software development for energy management applications or analytics, reporting, and charting software.

As a Senior Full‑stack Developer (Lead) at PUMA, you will play a pivotal role in driving our software development initiatives forward. You will lead the charge in new feature development, collaborating closely with our internal product owner and business stakeholders to plan and execute projects effectively, ensuring alignment with the defined roadmap and business requirements. Your responsibilities will span the entire development lifecycle, from architecture and design to implementation and optimization.

Additionally, you will serve as a bridge between internal stakeholders, who define the roadmap and business requirements, and our third‑party development team (consulting firm). In this capacity, you will lead the development efforts with the external team, filling the gap between internal objectives and the external development process, thus ensuring seamless communication and alignment of objectives across all stakeholders.

In this role, your responsibilities will include:

• Leading new feature development efforts, including effort estimation, planning, and roadmap creation.
• Overseeing PUMA’s front‑end, back‑end, and database development efforts, contributing to design and architecture decisions.
• Leading a pragmatic modernization roadmap; deciding rewrite vs. refactor, retiring legacy MVC where appropriate, and laying down microservices + SPA foundations.
• Working closely with internal and external users such as data analysts and client Energy Managers to gather feedback and translate user stories into functional applications.
• Identifying bugs and bottlenecks, determining root causes, and proposing solutions to enhance system performance.
• Ensuring the best possible performance, quality, and responsiveness of our applications and databases.
• Planning for scalability and future capacity of our servers and databases.
• Coordinating resources and timelines for multiple projects related to feature releases and improvements.
