    The Role


    Are you a seasoned developer with a passion for building scalable, high-impact software solutions? Do you thrive in an environment where you can make strategic, hands‑on contributions to cutting‑edge technology? At ONYX Insight, we're looking for a Senior Software Developer to join our growing team and play a key role in shaping the future of our tech stack.

    This is not just another developer role – it's an opportunity to architect, develop, and refine the technology that powers the future of renewable energy. With your expertise in modern C# .NET and React, you'll be pivotal in delivering robust solutions that support our core platforms and products.

    At ONYX Insight, we believe in empowering our teams to innovate, solve complex problems, and have a real‑world impact. As a senior developer, you'll be in the driver's seat, making critical decisions, mentoring your peers, and driving the technical direction of our platforms.

    Key Responsibilities

    • Lead, Build, Deliver: Own the design, development, and deployment of new features across both backend and frontend systems.
    • Mentor & Inspire: Provide guidance and mentorship to developers, promoting best practices, knowledge sharing, and a culture of continuous improvement.
    • Innovate: Collaborate with cross‑functional teams to create intuitive, high‑performance solutions that deliver value to our users.
    • Shape the Future: Influence our system architecture and contribute to the long‑term technology strategy.
    • Craft Scalable Solutions: Write clean, maintainable, and scalable code using modern C# .NET (6‑9) and React that stands the test of time.
    • Champion DevOps: Partner with platform engineers to support CI/CD pipelines and infrastructure automation, ensuring efficiency and reliability.

    Ideally, you'll have/be:

    • 5+ years of experience in commercial software development with a focus on modern C# .NET.
    • A strong, hands‑on background in React and frontend development (2+ years).
    • Proven experience leading technical initiatives and owning system architecture.
    • Deep understanding of scalable, secure application design and microservices architecture.
    • Familiarity with cloud platforms, preferably AWS.
    • Proficiency with relational databases, ideally PostgreSQL.
    • Knowledge of Agile methodologies and modern software delivery practices.
    • Exceptional communication and collaboration skills, with a proactive mindset focused on delivering tangible results.
    • A passion for solving real‑world problems with technology.
