This Cambridge technology company are growing their core engineering team; a half dozen senior engineers who collaborate closely on new projects. As a skilled Senior RTL Engineer with FPGA experience, you'd be working alongside peers with similar skills, as well as developers working in C++ and Rust. These technologies interface and form the backbone of a robust, high-speed and integrated solution, for deployment in high-connectivity locations worldwide. Extensive, demanding algorithmic work is performed on top-end FPGAs from leading vendors, and these are heavily populated, utilising all available blocks. Transactions are event driven and require an extremely rapid turnaround. But, this leads to interesting and challenging work which the team very much enjoy - and hope you would too. To be considered for this role, your CV will show: Extensive commercial-grade RTL experience, working on production FPGA projects where there is significant low-latency processing, and architectural considerations matter. Proficiency with Intel Quartus, AMD Vivado or comparable design tools. A collaborative approach, including experience working with firmware and/or software engineers, and ideally DevOps engineers.

Ecm Selection is a dynamic London tech start-up seeking a Senior Software Engineer. You will take on a technical lead role while also contributing individually, collaborating closely with the CTO and the software team. Ideal candidates will have robust experience with Rust and C/C++, capable of mentoring juniors and offering strategic insights. With a hybrid work environment and quarterly in-person meetings, candidates should be based in London or able to travel there. A competitive compensation package and share options are available.

Overview This London tech start up is disrupting the global transport sector through their innovative software solutions. They are a growing team and are currently looking for a senior software engineer to join them in a technical lead and individual contributor role (working closely with the CTO and software team). They will have experience using Rust as well as C / C++ on efficient optimal code bases. They will be able to mentor junior members of the team, project manage, and provide useful technical strategic insight into the business. Projects can be fast paced, and so they are keen that past start up experience can be utilised. Similarly, they are pro LLMs for prototyping, so they want someone who can utilise modern ML tools but also has the technical experience to understand the code being written. Requirements Having excelled at university (1st / 2.1 STEM degree from a top ranked university), you will have extensive industry experience building mission critical software products used in live environments. You'll be an individual contributor and software polyglot, but more recently delivered projects using Rust (and ideally the wider Rust ecosystem). You will have worked in one or more start ups, understanding how fast paced projects can be delivered successfully. This should include the use of LLMs for code prototyping. You can demonstrate leadership qualities through past experience including motivation and inspiration through technical leadership, mentoring, and contributions to company strategy / business. The company is based in central London but operate a highly hybrid work environment (although one week every quarter, the company meets in person at their London offices for a strategy get together). Interested candidates therefore are expected to be based in London, or able to come to London for such meetings. Further, there can be occasional overseas travel for client meetings. On offer is an excellent compensation and possible share options. Note, no company sponsorship is available - all interested applicants should have full, unrestricted rights to work in the UK.
