Location: Mississauga, ON (on-site)
Start date: November 3, 2025
Application: Email your resume to info@sterilabs.ca (see “How to Apply”)

SteriLabs is an ISO 17025–accredited medical device testing and validation laboratory serving medtech innovators across Canada. We’re adding an experienced Microbiologist / Study Lead for a 24-month term to lead sterilization validations, own sterility testing deliverables, support biochemistry cleaning-assay work, and help maintain our ISO 17025 QMS. You’ll be client-facing within weeks, not months.

What you’ll do

• Lead sterilization validations (steam and low-temperature hydrogen peroxide) end-to-end: protocol design, BI strategy/placement, growth promotion, method suitability/neutralization, execution oversight, data review, and client-ready reports.

• Own sterility testing deliverables, including planning, execution oversight, deviation/CAPA drafting, and trending.

• Collaborate on EtO and disinfection studies with peer Microbiologists; contribute to risk assessments and study design.

• Support biochemistry cleaning validations as needed (e.g., MicroBCA, hemoglobin/TMB, carbohydrate markers, H₂O₂ assay): sample prep, data review, and integrating results into final reports.

• Maintain ISO 17025 QMS discipline: SOP/LWI updates, equipment logs and calibrations, document control, training records, internal audits, change controls, and CAPA follow-through.

• Interface with clients for protocol reviews, technical rationales, and results walkthroughs; represent SteriLabs professionally in meetings and emails.

What you bring

• BSc/MSc in Microbiology, Biotechnology, or related life science.

• 2–5+ years in a regulated lab (medical device, CRO, or hospital/industry lab) with hands-on sterilization validation (steam and/or H₂O₂) and sterility testing responsibility.

• Strong technical writing (protocols, deviations/CAPA, final reports) and comfort presenting decisions to clients and auditors.

• Working knowledge of ISO 17025 practices (traceability, records, uncertainty awareness), document control, and internal audit participation.

• Nice to have: exposure to EtO cycle validations; disinfection/bioburden recovery; assay (protein/BCA, Hb-TMB, carbohydrates) or H₂O₂ quantitation; radiation dose-setting literacy.

• You’re rigorous, organized, and calm under deadlines. Able to run multiple studies without compromising quality.

Work eligibility & on-site requirement

• On-site role in Mississauga, Ontario.

• Applicants must already be legally eligible to work in Canada and be available to start November 3, 2025.

Why join SteriLabs

• Impactful work that directly supports product safety and regulatory compliance.

• ISO 17025 environment with clear study ownership and exposure across micro + biochemistry.

• Tight-knit, responsive team that values reliability, clarity, and high standards.
