About the role:

Everfox is hiring Senior Software Engineer to support our team in London, UK. This role suits a strong senior software engineer who wants to go beyond writing code. You do not need a formal delivery-management background, just solid engineering and an appetite to take on more: design, architecture, coordination, planning and end-to-end delivery. Generalists are welcome. What counts is the quality of your reasoning and problem-solving and how you take on a hard challenge, not the exact languages on your CV.

You will split your time between hands-on work on our cross-platform desktop and mobile apps and managing delivery across the end-point software layer of the Everfox Hardsec product line. You will shape and deliver the end-point software that gives users access to our secure browsing and VDI solution, owning its design, development and overall user experience. The work spans Linux and Windows desktop applications and mobile apps on Android and iOS, with a focus on quality, usability and enterprise integration.

You will also work closely with our testing lead on release management so that each multi-platform release ships reliably and on time. You will help shape the roadmap, coordinate delivery across our Hardsec solutions, and work with the stakeholders who depend on this software. The work sits on the critical path and is highly visible, directly supporting the commercial priorities of the business, so what you ship lands quickly with the people who use it.

If you enjoy owning hard technical problems end to end while keeping a team aligned and delivering, this role is for you.
