Senior Assembly Language Programmer information

What does a Senior Assembly Language Programmer do?

A Senior Assembly Language Programmer designs, writes, and maintains low-level software using assembly language, which directly interacts with computer hardware. They optimize critical system components for performance and efficiency, often working on embedded systems, operating systems, or device drivers. Their responsibilities include debugging complex code, improving system stability, and collaborating with hardware engineers to ensure software integrates seamlessly with hardware. With their advanced knowledge, they also mentor junior programmers and contribute to architectural decisions.

What are some common challenges faced by Senior Assembly Language Programmers when working on legacy systems?

Senior Assembly Language Programmers often encounter challenges such as deciphering poorly documented or outdated code, ensuring compatibility with modern hardware, and troubleshooting obscure bugs that may not manifest in higher-level languages. Collaborating with cross-functional teams can also be complex, as few colleagues may have deep assembly expertise. To address these issues, programmers typically rely on thorough code reviews, strong analytical skills, and effective communication to bridge knowledge gaps and ensure the stability and performance of critical systems.

What is the difference between Senior Assembly Language Programmer vs Embedded Systems Engineer?

AspectSenior Assembly Language ProgrammerEmbedded Systems Engineer
CredentialsTypically requires a degree in Computer Science or Electrical Engineering, with experience in assembly languageRequires a degree in Electrical Engineering, Computer Engineering, or related fields, often with knowledge of embedded programming
Work EnvironmentPrimarily focused on low-level programming, debugging hardware interfaces, and optimizing assembly codeDesigning, developing, and testing embedded systems, often involving both hardware and software components
Industry UsageUsed in industries like aerospace, defense, and hardware manufacturing where low-level programming is criticalCommon in consumer electronics, automotive, medical devices, and IoT sectors

The main difference is that Senior Assembly Language Programmers specialize in low-level assembly coding for hardware optimization, while Embedded Systems Engineers work on designing and developing complete embedded solutions, often combining hardware and software skills. Both roles require technical expertise but focus on different aspects of embedded technology.

What are the key skills and qualifications needed to thrive as a Senior Assembly Language Programmer, and why are they important?

A Senior Assembly Language Programmer needs deep expertise in low-level programming, computer architecture, and debugging, usually supported by a degree in computer science or a related field and several years of relevant experience. Familiarity with specific assembly languages (such as x86 or ARM), integrated development environments (IDEs), debuggers, and version control systems is critical. Exceptional problem-solving skills, attention to detail, and the ability to communicate complex technical concepts clearly are standout soft skills. These competencies ensure the delivery of efficient, reliable, and optimized code essential for performance-critical systems.

Job description

About the Position

We are looking for an experienced software engineer to work on code generation in the OxCaml compiler, which is open source. OxCaml is Jane Street's variant of the OCaml language, equipped with powerful features for high-performance and parallel programming, with data race freedom guarantees.

This role involves the full cycle of identifying new optimizations, coding, testing, benchmarking, and deployment. There will be the opportunity to work across a wide variety of intermediate representations, including CPS, SSA, and maybe even Sea of Nodes. This role will also allow you to interact with many different groups and exceptional individuals across Jane Street worldwide.

About You

The ideal candidate will be super productive: fast at writing correct code, willing to use AI assistance to get changes to production faster, and experienced with debuggers (e.g., lldb, gdb) and low-level Linux tools. Having knowledge of x86-64 and AArch64 architectures at the assembly language and architectural level is a plus.

We are happy to consider candidates with experience on any compiler toolchain, although knowledge of LLVM would be useful. No knowledge of the OCaml or OxCaml languages is required-we can teach you what you need to know.

We are particularly interested in candidates who have proven experience managing a team of developers, and who would enjoy doing that alongside their normal technical work.

If you're a recruiting agency and want to partner with us, please reach out to agency-partnerships@janestreet.com
