Software Engineer View and Apply

The successful candidate will be joining a strong team of experienced messaging engineers and be able to demonstrate leadership and team working around the design and implementation of new features needed to maintain the technological leadership of Isode in the delivery of messaging products. Reviewing the work of and mentoring other Isode developers is also part of the role. While server-side work is the focus, client-side development (Web and desktop applications) is also part of the team’s responsibility. Although the primary role is that of development, the successful candidate must be able to demonstrate a record of success across the development cycle including requirements capture, design, implementation, testing, documentation, and support.

The primary development language is C++, though the company is transitioning towards using newer languages – in particular Rust. Our development environment is based on Git, with reliance on the Atlassian toolset (JIRA, Confluence, Bitbucket and Bamboo) to provide a continuous integration workflow so you can expect to spend some of your time working with these tools. While we do offer both flexible and remote working options, for this role the successful candidate is expected to spend at least part of their time working from the Hampton office.

Required skills:

• Strong record of developing and delivering robust, reliable and scalable products on Windows and Linux platforms.
• A strong background in C++ is essential, as is a willingness to learn new languages and technologies.
• Messaging standards: IMAP, SMTP, X.400, ACP127.
• Network programming: TCP/IP, familiarity with other Internet standards (e.g. LDAP).
• Security: PKI, TLS, X.509, OpenSSL, S/MIME, Security Labels.
• Debugging and development tools: Visual Studio, GCC, Clang, Valgrind, GDB, WireShark, ASAN.

A strong record of developing and delivering messaging servers implementing open standards is highly desirable.

All of our products are based on Open Standards, and we have a strong history of leading the specification and development of Open Standards in our technology areas. While Isode core products are large, robust, and complex protocol servers, they require User Interfaces which enable the servers to be administered and operated.
