This role is ideal for someone who has worked hands-on with LIMS platforms such as Labbit, LabAdvantage, or similar systems, and who understands the nuances of clinical, molecular, and diagnostic lab operations. You will partner closely with laboratory stakeholders, product managers, and cross-functional engineering teams to translate real-world lab processes into reliable, compliant, and scalable software solutions. Key Responsibilities Lead the design, configuration, and customization of LIMS systems to support end-to-end laboratory workflows (sample accessioning, testing, results, reporting, QC, and data integration). Serve as a technical subject matter expert for LIMS workflows, lab operations, and healthcare terminology. Work directly with laboratory users to gather requirements, map workflows, and implement system configurations that improve efficiency and data quality. Build and maintain custom extensions, integrations, and automation around LIMS platforms using modern software engineering practices. Integrate LIMS with upstream and downstream systems (instruments, ELNs, EMRs/EHRs, data warehouses, APIs). Ensure systems meet regulatory and compliance requirements (e.g., CLIA, CAP, HIPAA, 21 CFR Part 11 where applicable). Review and improve existing LIMS configurations to support scalability, performance, and maintainability. Mentor junior engineers and provide technical leadership across LIMS-related initiatives. Collaborate with QA, DevOps, and product teams to support testing, validation, deployment, and ongoing support. Required Qualifications Education: Bachelor’s degree in Computer Science Engineering, or related field (or equivalent experience) Experience: 8 to 10+ years of professional software engineering experience, with significant hands-on work in LIMS environments. Extensive experience configuring and customizing LIMS platforms such as Labbit, LabAdvantage, or comparable systems. Strong understanding of laboratory workflows, including sample lifecycle management, testing processes, and results management. Deep familiarity with healthcare and laboratory terminology, data standards, and operational constraints. Experience building integrations and APIs (REST, HL7, FHIR, or proprietary lab/instrument interfaces). Proficiency in at least one modern programming language (e.g., Java, C#, Python, JavaScript). Strong SQL and data modeling skills, particularly for complex scientific or clinical datasets. Ability to translate lab requirements into technical designs and system configurations. Excellent communication skills and comfort working with both technical and non-technical stakeholders. Preferred Qualifications Prior experience in clinical diagnostics, molecular labs, or reference laboratories. Experience with instrument interfacing and automation. Familiarity with validation documentation and regulated software development. Experience working in agile development environments. Exposure to cloud-based LIMS or SaaS laboratory platforms. What Success Looks Like Laboratory teams trust you as a go-to technical partner who understands how the lab really works.
