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.

About 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. If you're passionate about building cutting-edge software and thrive in a collaborative environment, we want to hear from you.

The Role

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.

If you're passionate about driving innovation and delivering high-quality software solutions, we invite you to join our team at PUMA.

Qualifications and Experience

We recognize that not all candidates will meet every qualification listed. If you're excited about this role and believe you bring relevant experience or transferable skills, we encourage you to apply.

The following qualifications, experience, and competencies are considered major assets:

• Bachelor's degree in Computer Science, Software Engineering, or equivalent.
• At least 10 years of software development experience in a professional capacity, including experience in building and leading small development teams and managing software projects.
• Ability to 'think with a product management hat' regarding product requirements and features.
• Skilled in modern, scalable web architecture: SPA + API patterns, and experienced moving from .NET Framework to .NET 8/9.
• Expert-level understanding of large-scale RDBMS design, preferably in the Microsoft SQL Server environment.
• Hands-on coding skills, using C#, HTML, CSS and JavaScript/jQuery.
• Ability to clearly communicate with both technical and non-technical team members.
• Hands-on application modernization to cloud-native on Azure, including service decomposition and stable API contracts.
• Experience with energy management applications or analytics, reporting, and charting software, including familiarity with reporting and charting libraries such as FusionCharts.
• Experience designing and implementing public APIs and RESTful endpoints, with documentation skills for client integration purposes.
• Practical use of Azure Functions where it reduces coupling and cost (e.g., event-driven workflows, background jobs).

This is a 40-hour per week salaried position in a hybrid work environment with flexibility for working hours.

The salary range is $110,000 to $130,000. We will consider your level of experience and responsibilities, competencies, and unique offering to our team.
