Software Engineer — Computation Kernels and Performance

About This Opportunity

Our talent team at Get A Job.ai is representing a confidential AI hardware company building next-generation computational systems. This is a critical role for an engineer who thrives at the intersection of hardware and software, designing and optimizing low-level kernels that power custom AI accelerators. You'll work in Paris alongside a multinational engineering team focused on performance, precision, and rapid innovation.

Responsibilities

• Develop and optimize low-level software primitives in C/C++, assembly, and architecture-specific intrinsics, primarily for RISC-V and ARM platforms
• Implement performance-critical kernels, runtime components, hardware abstraction layers, drivers, and firmware operating in bare-metal or highly constrained environments
• Collaborate with hardware architects and RTL/design teams to define and validate hardware-software interfaces, memory maps, register interfaces, interrupts, synchronization mechanisms, and boot flows
• Analyze and optimize software for latency, throughput, memory footprint, instruction count, and efficient use of processor and accelerator features
• Bring up and debug software on simulation, emulation, FPGA, and silicon platforms, including low-level hardware/software integration issues
• Develop validation tests, benchmarks, and diagnostic tools for new processor, DSP, accelerator, and SoC functionality
• Contribute to architecture decisions around ISA extensions, compiler intrinsics, memory hierarchy, DMA, cache/coherency behavior, and software-visible hardware features

What We're Looking For

• Bachelor's, Master's, or PhD in Computer Science, Computer Engineering, or a related field
• Strong experience in low-level systems programming using C/C++ and assembly, with excellent understanding of how compiled software maps to machine instructions and hardware behavior
• Deep familiarity with bare-metal development, including startup code, linker scripts, memory layout, MMIO, interrupts/exceptions, timers, synchronization, and direct peripheral access
• Strong understanding of computer architecture, including pipelines, caches, memory hierarchies, virtual/physical addressing, atomics, DMA, and performance implications of different access patterns
• Hands-on experience with RISC-V and/or ARM architectures, instruction sets, calling conventions, ABI concepts, and architecture-specific intrinsics
• Experience debugging hardware/software interactions using tools such as GDB, JTAG, trace/debug interfaces, simulators, emulators, or FPGA platforms
• Ability to read hardware specifications, register descriptions, and RTL-level documentation and translate them into robust software implementations
• Strong performance-analysis and optimization skills, including profiling, disassembly inspection, compiler optimization behavior, and hand-tuned assembly where appropriate
• Proficient English required; French is a plus

How We Work With You

Candidates apply directly through Get A Job.ai. Our recruiters conduct an initial screening to understand your background and technical expertise. We then coordinate interviews with our client, which include technical deep-dives, culture assessment, reference checks, and a take-home technical assignment. You should not contact the client directly; all communication flows through our team to ensure a smooth, professional process.

Pay

Compensation details will be discussed during the screening process and are competitive with the European deeptech market. Our client offers equity participation, relocation support, healthcare coverage, pension contributions, professional development budgets, and 25 days of paid time off plus public holidays.

Equal Opportunity: Get A Job.ai is committed to inclusive hiring practices. We welcome candidates from all backgrounds and work to ensure fair, equitable access to opportunities.
