• Embed with banking clients to deeply understand their workflows, constraints, regulatory context, and the strategic outcomes they're chasing • Translate ambiguous business problems into specific, testable hypotheses — then design and ship the solution against them • Own product decisions on live engagements: scope, sequencing, UX, what to build vs. what to leverage from the Titan platform • Build full-stack, leaning on UI/UX and front-end craft to deliver client-facing experiences that feel native and trusted • Run agentic workflows end-to-end: design the agent, configure the toolkit, evaluate, ship, iterate • Codify what you learn into reusable patterns, playbooks, and platform feedback so the next engagement starts further down the field • Partner with the broader Titan team — platform, GTM, ops — and represent the client's reality back to product and engineering

• Interact with key internal and external customers and partners regarding system safety topics. • Work with or lead a small team of System Safety engineers in defining, implementing, and verifying System Safety requirements to ensure that the inherent risks are mitigated. • Apply the systems engineering process to define and verify launch vehicle and ground support equipment requirements to ensure safe operations and conduct system safety analyses to architect and implement a safe and robust system. • Manage interface with customer safety and launch integration personnel and support ground operations and launch mission working groups as requested. • Conduct system level analysis of next generation mission concepts and designs to maximize mission success without compromising compliance with customer, government, and internal flight safety requirements.

Role Description As a Driver Engineer, you'll work on the layer that sits between Modular's compiler and runtime stack and the silicon — the devices, contexts, queues, synchronization primitives, memory allocators, networking, and collectives that every kernel and graph execution depends on. Your work directly affects how reliably and efficiently MAX and Mojo run across NVIDIA, AMD, Apple Silicon, and emerging accelerators, and how cleanly kernel and graph authors can target them from Mojo and Python. This is the team that makes "it just works on a new accelerator" actually true. LOCATION: Candidates based in the US or Canada are welcome to apply. You can work in our office in Los Altos, CA or remotely from home. What you will do - Implement and extend core driver abstractions — Device, Context, Queue, Memory, Function (kernel representation and launch) — across diverse hardware backends, including bindings that expose vendor-specific functionality where it matters. - Contribute to multi-accelerator and multi-node communication and collectives primitives that underpin large-model inference, using technologies like NVLink, RDMA (Infiniband, RoCE, EFA), and sockets — via a combination of direct programming and broker libraries like UCX. - Improve diagnostics and error reporting across our asynchronous execution stack — turning low-level driver failures into actionable messages for kernel and graph authors in production environments. - Partner with peer teams — Kernels, Graph Compiler/Runtime, and Serving — to build and refine the surfaces they consume in the Mojo standard library and MAX framework. - Participate in design discussions, code reviews, and collaborative software development to uphold high engineering standards. - Contribute to a fully open source project — everything you build will be public and part of our GitHub repo. Qualifications - 3+ years of experience writing high-performance, low-latency production systems C++ (modern C++17/20), with strong instincts for ownership, lifetime, ABI stability, concurrency, and parallelism. - Hands-on experience with at least one accelerator driver-level API — CUDA Driver API, HIP, Metal, or Vulkan compute — including streams, events, contexts, and module loading. Familiarity with async allocators and IPC is a plus. - Working understanding of accelerator execution and memory models — stream ordering, host↔device transfers, and pinned memory. Exposure to peer access and multi-GPU topologies (NVLink/xGMI, NUMA) is a plus. - Solid instincts for library and API design — naming, layering, ergonomics. - Strong debugging skills in asynchronous, multi-device systems — GDB/LLDB, sanitizers, CUDA/HIP error modes, race conditions, leaked resources. - A proactive, collaborative mindset, intellectual curiosity, and drive to identify and solve complex technical challenges as part of a high-performing team. Requirements - Experience with asynchronous runtimes, custom memory allocators, or RDMA-based networking (Infiniband, RoCE, EFA, UCX, NIXL, MPI, NVSHMEM/ROCSHMEM/OpenSHMEM) is helpful but not required. - Exposure to non-NVIDIA accelerators in production — AMD ROCm, Apple Metal, etc. - Experience with zero-copy tensor interoperability — DLPack, the CUDA Array Interface, or similar. - Familiarity with Mojo, or recent open-source contributions to systems projects (LLVM, PyTorch, JAX/XLA, TVM, IREE, vLLM, TRT-LLM). - An advanced degree in Computer Science or a related field. Benefits - Amazing Team: We are a progressive and agile team with some of the industry’s best engineering and product leaders. - World-class Benefits: Premier insurance plans, up to 5% 401k matching, flexible paid time off, and more are available to you! - Competitive Compensation: We offer very strong compensation packages, including stock options. - Team Building Events: We organize regular team onsites and local meetups in Los Altos, CA as well as different cities. Traveling 2-4 times a year is expected for all roles. The estimated base salary range for this role to be performed in the US, regardless of the state, is $167,000.00 - $286,000.00 USD. The estimated base salary range for this role to be performed in Canada, regardless of the province, is $158,000.00 - $270,000.00 CAD. The salary for the successful applicant will depend on a variety of permissible, non-discriminatory job-related factors, which include but are not limited to education, training, work experience, business needs, or market demands. This range may be modified in the future. The total compensation for a candidate will also include annual target bonus, equity, and benefits, with equity making up a significant portion of your total compensation. For candidates who fall outside of the listed requirements, we nevertheless encourage you to apply as we may have openings that are lower/higher level than the ones advertised.
