Senior Software Engineer C#

Are you a C# expert ready to move beyond coding and truly shape the future of real‑time software products? We’re looking for an experienced technical leader to drive innovation, mentor developers, and architect the next generation of our high‑performance systems.

If you thrive in an Agile environment and have a passion for performance‑critical work (think algorithms, real‑time data handling, and signal processing), this is your opportunity to make a massive impact.

• Lead the design, maintenance, and modernisation of our core software architecture alongside your peers and the Development Manager.
• Mentor and coach Software Development Engineers across teams, setting standards and evangelising best practices (including through our Community of Practice).
• Lead the full lifecycle of major "epic" work from feature design with the Product Owner to final implementation and deployment.
• Leverage your deep expertise in C# to tackle complex, performance‑critical tasks like data acquisition and real‑time data decoding.
• Benefit from dedicated "blue‑sky" time for professional development, technology investigations, and exploring new feature feasibility.
• Ensure all code meets the highest quality, company, and regulatory standards, actively engaging with the full SDLC (Code Review, Unit/Integration Testing, Root Cause Analysis).

• Expert C# proficiency and demonstrable experience in performance‑critical software.
• Extensive experience in software architecture design and maintenance.
• Hands‑on experience with signal processing, data acquisition, or real‑time systems.
• Proven coaching and technical leadership skills.
• Deep practical knowledge of Agile/Scrum methodologies.
• Excellent technical communication skills – ability to lead workshops, share knowledge, and advocate for change.

Advantageous:
Experience with UI frameworks (WPF, etc.), hardware interfacing/drivers, multi‑threading, or deep product domain knowledge (electronics/test and measurement).
