Zusammenfassung

Ubitium seeks a Senior Software Engineer to own the software stack from compiler to bare-metal for a RISC-V SoC. You will develop tooling, write firmware, and optimize signal processing under real-time constraints, while bringing up software on pre-silicon and silicon platforms.

Join a team of hardware-aware engineers in a hybrid setup (4 days onsite, 1 day remote) with relocation support. A Master’s degree and 10+ years in related work are expected.

Qualifikationen

• Strong C, modern C++ (C++17/20, STL, Boost) and Python.
• Solid foundation in algorithms and hardware/software system architecture.
• Experience close to hardware, with SoC design knowledge and RTL familiarity.
• Experience with agentic programming and deep expertise in at least one area.
• Master's degree or equivalent experience with 10+ years in relevant work.
• Relocation required; 4 days on-site and 1 day remote, policy may change.

Aufgaben

• Develop software stack including compiler, mapping tools, and low-level tooling.
• Write bare-metal, firmware and OS-level software for a RISC-V SoC.
• Implement and optimise signal-processing and ML inference kernels under real-time constraints.
• Bring up and test software on pre-silicon and silicon hardware, including low-level tests.
• Collaborate closely with hardware designers in a fast feedback loop.

Jobbeschreibung

At Ubitium, we believe the best engineering happens when people with different perspectives tackle hard problems together. We welcome applicants from all backgrounds and experiences. What matters most is curiosity, skill, and the drive to build technology that improves the world. If that resonates with you, we’d love to hear from you. Our team members come from some of the best universities in the world and left some of the largest tech companies to build something truly remarkable.

Tasks

We are looking for a Senior Software Engineer who is at home across our processor software from ported libraries and the compiler down to bare-metal and operating systems. Your team will: develop our software stack, including compiler, mapping tools, low-level tooling, simulation and debug infrastructure; write bare-metal, firmware and OS-level software for our RISC-V SoC; implement and optimise signal-processing and inference kernels under real-time constraints; bring up, test and port software on pre-silicon platforms and on silicon, including low-level hardware tests; and work in a close feedback loop with our hardware designers.

Requirements

• Strong C, modern C++ (C++17/20, STL, Boost) and Python.
• A solid foundation in algorithms and in hardware/software system architecture.
• Experience working close to the hardware, with a good understanding of system-on-a-chip design, processor architecture and microarchitecture, and some familiarity with RTL and hardware design.
• Experience with agentic programming.
• You know your way around all of these fields, and go deep in at least one: i ) compiler development and code generation; ii) low-level tooling, simulation and performance analysis; iii) low-level embedded or systems software, operating systems and real-time; iv) signal processing, numerical computation and ML inference
• Master's degree (or equivalent experience) and 10+ years of relevant experience.
• Relocation required. Currently 4 days on-site, 1 day remote. Policy may change.

Nice to have

• Parallel and data-flow execution models: SIMT, predicated execution, branch divergence.
• Mapping and optimisation algorithms: graph algorithms, place-and-route / EDA, CGRA or FPGA mapping, ILP solvers.
• Kernel-level optimisation: vectorisation, data layout, memory hierarchy, fixed-point and quantised arithmetic.
• Post-silicon validation and hardware bring-up, including directed and random test generation.
• Porting code to new platforms.
• Exposure to: RISC-V, LLVM, CUDA, OpenCL, Verilog, Verilator, QEMU, GDB, JTAG and on-chip debug, OpenSBI, bootloaders, HAL, Linux kernel and device drivers, device tree, Zephyr, Yocto/OpenEmbedded, BLAS/LAPACK/OpenBLAS.

Benefits

• Competitive salary plus stock options
• 30+ days of paid vacation
• Relocation support
• Full German social security and universal healthcare
• A modern office
• Free snacks, coffee, and drinks
• Work with people who actually know their stuff – computer architects, hardware nerds, and engineers who love tough problems.
• A culture where new ideas matter, but so does respect and collaboration.
• Space to grow: pick up new skills, dig into areas that interest you, and shape your own path.
• Get hands-on with real implementations of AI and signal processing – not just slides or buzzwords.
• An inclusive team where different perspectives are valued and everyone contributes.

We are constantly looking for talent. We recruit through multiple channels – friends & colleagues, universities and professors we know, recruiters, conventions, e-mails and LinkedIn. Join us today.
