Job Description

ApplianSys is a UK-based entrepreneurial company and the global leader in specialist network appliance products. Our solutions are used in 160 countries, and the business is on the brink of a significant upward trajectory due to much larger sales opportunities, particularly within large-scale national education projects. We're looking for a talented Senior Software Developer to join our team and play a key role in shaping the future of our network solutions.

Location: Coventry, UK (Hybrid with flexible remote options)

About the Role:

As a Senior Software Developer, you'll be more than just a coder. You'll be a product developer who contributes to the design, development, and implementation of our cutting-edge network appliance products. This role requires a deep understanding of networking protocols, Linux systems, and Python programming, and the ability to apply that knowledge to solve complex technical challenges.

Key Responsibilities:

Design, develop, and maintain software for ApplianSys products and upgrades. Work with a range of network protocols (HTTP, DNS, DHCP, etc.), Linux, and Python. Contribute to both software and hardware development. Maintain and extend existing product components (HTTPS interception, caching engines, etc.). Focus on non-functional requirements (test coverage, maintainability, performance, and scalability). Contribute to high-level and detailed design of new products and components. Participate in platform architecture and evolution. Research and select third-party components. Contribute to and extend open-source projects. Evolve methodologies and pursue DevOps approaches. Gain deep product and market knowledge. Contribute to product management by reviewing market and technology trends.

Specifically, we're looking for someone with:

Fluency in Linux and network protocols. Strong Python skills. Solid skills with Web applications technologies (HTML, JavaScript, CSS). Expertise in HTTP, DNS, DHCP, and related domains.Experience with networking services (Squid, nginx, BIND, ISC Kea, etc.). Aptitude for product development, not just software engineering. Broad technical and market knowledge (hardware, network equipment, etc.). Ability to solve complex technical challenges (e.g., HTTPS caching issues). Understanding of Windows Updates or Microsoft software delivery mechanisms.
Bonus Points:

Full-stack web developer experience. Experience in the education technology domain. Knowledge of C, C++, or Rust on Linux. Experience with AI tools for software engineering and product automation. Strong team player with excellent communication and influencing skills. Experience working with large codebases and distributed version control.
