Backed by leading life sciences investors, we have achieved industry-leading diagnostic yield and unit economics through a vertically integrated software stack that spans from sample to report. At the core of our success is a proprietary clinical platform that uniquely enables our workflows, allowing us to solve complex biological data challenges at scale. With a strong global presence across our internal teams and external partnerships, we offer the stability of a well-funded industry leader combined with the agility of a high-growth tech company.About the Role We are looking for an experienced, production-focused Senior Software Engineer to lead the architectural evolution of our core germline clinical bioinformatics pipeline.Our production pipeline is a large-scale, high-throughput system. We continue to push the frontier of diagnostic capabilities while heavily scaling our operations. As part of a lean, high-caliber engineering team, you will take ownership of complex technical challenges, delivering clean, rigorously tested, and heavily optimized code.Important Note: This is strictly a production software engineering role, not an academic research, data science, or scripting position. We are specifically looking for highly technical engineers with a strong Computer Science background who build robust, high-performance systems. If your primary experience is writing R or Python scripts for data analysis or academic research, this role will not be a fit.What You Will DoHigh-Performance Engineering: Identify bottlenecks and rewrite/optimize core primary, secondary, and tertiary bioinformatics pipelines utilizing Rust for maximum performance and memory safety.Systems Integration: Seamlessly bridge high-performance Rust modules with our existing Python infrastructure using tools like PyO3 and Maturin.Database Architecture: Design, implement, and scale complex database schemas (MongoDB and RDBMS) to manage massive, high-throughput genomic datasets efficiently.Clinical-Grade Feature Development: Design, develop, validate, and deploy cutting-edge algorithms for variant detection and scoring on our high-performance CPU and GPU compute clusters.Production Quality Assurance: Enforce strict software quality standards, SDLC best practices, and automated testing to ensure our clinical results are perfectly accurate and reproducible in a highly regulated environment.Required QualificationsEducation & Experience: Master’s or Bachelor’s degree in Computer Science, Software Engineering, or a closely related technical field, backed by 5+ years of dedicated industry experience in production software engineering.Rust & Python Expertise: You are an expert in both Rust and Python. You understand Python internals, packaging, and design patterns, and you are highly proficient in writing memory-safe, concurrent Rust code (including Python extensions).Database Architecture: Strong background in database design, data modeling, and performance tuning. You have deep experience with MongoDB, relational databases (RDBMS), normalized schemas, and complex data migrations.Production Engineering Rigor: You do not write \\\"scripts\\\"; you build systems. You have deep expertise in the Software Development Lifecycle (SDLC), testing frameworks, mocking strategies, and writing modular, deployable code.Bioinformatics Domain Knowledge: Strong production experience working with standard genomic file formats (FASTQ / BAM / CRAM / VCF), variant calling algorithms, and high-throughput sequencing platforms (short- and long-read).Linux/Bash Mastery: You are highly comfortable debugging complex systems interactions in a Linux environment and writing robust shell automation.Preferred QualificationsAdvanced Degree: PhD in Computer Science, Software Engineering, or closely related field.Typescript: Experience writing Typescript to interface with our MongoDB data layer and execute workflows.Compensation and BenefitsSalary minimum $120,000 - based on experienceEmployee Stock Options Plan (ESOP)Paid Time Off (PTO)Medical, Dental, Vision, Life, and Disability insurance401k Retirement Savings Plan","company":"Variantyx","rawCompany":"variantyx","city":"Millbrae","state":"CA","isRemote":false,"isActive":true,"createdAt":"2026-10-24T03:55:48.559Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"19-1029.01","title":"Bioinformatics Scientists","slug":"bioinformatics-scientists"},{"code":"15-2099.01","title":"Bioinformatics Technicians","slug":"bioinformatics-technicians"}],"industries":[{"code":"513210","title":"Software Publishers","slug":"software-publishers"},{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"},{"code":"541714","title":"Research and Development in Biotechnology (except Nanobiotechnology)","slug":"research-and-development-in-biotechnology-except-nanobiotechnology"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Senior Software Engineer, Bioinformatics (Rust and Python)","description":"About Variantyx Join our rapidly growing, engineering-driven organization and help build the software that powers the future of whole-genome diagnostics.
