What are the typical daily responsibilities of a Language Engineer?

Language Engineers typically spend their days developing, testing, and improving language models and algorithms used in applications such as chatbots, voice assistants, and translation tools. They collaborate closely with data scientists, software engineers, and linguists to collect and annotate data, refine language processing workflows, and address real-world linguistic challenges. Regular tasks may include designing rule-based systems, implementing machine learning models, evaluating system performance, and troubleshooting language-specific issues. This role often requires balancing independent work with team collaboration to ensure language technologies meet both technical and user experience goals.

What is a Language Engineer job?

A Language Engineer designs, develops, and optimizes language-related technologies, such as natural language processing (NLP) models, speech recognition systems, and machine translation tools. They work with linguistic data, improve language models, and create rules and algorithms to enhance text and speech processing. This role often involves collaborating with software engineers, data scientists, and linguists to refine language-based AI systems. Language Engineers also help expand language support for AI applications by curating datasets and improving system accuracy.

What are the key skills and qualifications needed to thrive in the Language Engineer position, and why are they important?

To thrive as a Language Engineer, you need a strong background in computational linguistics, natural language processing (NLP), and programming languages such as Python or Java, often supported by a degree in computer science, linguistics, or related fields. Familiarity with NLP libraries (e.g., NLTK, spaCy), machine learning frameworks, and tools for text annotation and data processing is highly beneficial. Strong problem-solving abilities, attention to detail, and effective communication skills are crucial soft skills in this role. These competencies enable Language Engineers to build robust language models, collaborate across interdisciplinary teams, and address complex language-related challenges in technology products.

Job description

About the Position
We're looking for Software Engineers with a background in programming languages to join one of our PL-focused teams at Jane Street.
Programming languages work at Jane Street spans a wide variety of different areas:
  • Language design and type systems. Designing language features and stronger type-level guarantees that let our developers express more of what they mean, and catch more mistakes at compile time.
  • Compilers and optimization. Investing in optimization, code generation, and backend work that translates directly into measurable speedups across the firm's most performance-sensitive systems.
  • Incremental and parallel computation. Building runtimes that can evaluate large, irregular, dynamic computation graphs incrementally and/or parallel across many cores and machines, with first-class attention to scheduling, memory, and resource accounting.
  • Support for high-performance computing, including work on tooling, verification techniques, and languages for hardware design, as well as support for programming GPUs and other ML accelerators.
  • Domain-specific languages. Designing, implementing, and evolving custom languages that power some of our most important internal platforms.
  • Tooling and developer experience. Profilers, debuggers, language servers, IDE integrations, documentation tools, and the surrounding infrastructure that makes a language genuinely pleasant to use at scale.

Some of this work involves working on open-source language implementations, like those of OCaml and Python, and for those areas, a meaningful portion of our work is open-source as well. Some of it involves custom languages and DSLs that we've built entirely in-house, some open-source, some purely internal.
We're looking for people who have:
  • Deep experience with-and love for-programming languages. There's no specific checklist; we are interested in people with experience in language design, type systems, compilers, runtimes, or DSL implementation
  • Top-notch programming skills
  • Strong interpersonal skills. Software engineering at Jane Street is highly collaborative, and we are looking for people who can work effectively in small, close-knit teams

No previous experience with OCaml or functional programming is required.
You only need to submit one application for Programming Language Engineering at Jane Street. We're excited to evaluate folks for areas across all of these roles, but if you feel like your experience relates best to a more specific area, please indicate that in the notes section of your application.
If you're a recruiting agency and want to partner with us, please reach out to agency-partnerships@janestreet.com.
