Medical Laboratory Scientist I / II (Founding Team)

Role Overview & Impact

Terrace Hall Laboratory is a new high-throughput CLIA clinical laboratory in Burlington, MA, going live in December 2026. Every sample we run is part of how healthcare is changing: faster, more accessible testing that helps people take charge of their health.

As a founding MLS, you'll help bring a new lab to life: validating assays on a new Beckman Coulter chemistry and immunoassay platform and setting the quality bar for a lab designed to scale across multiple sites.

Core Responsibilities

Both levels

• Perform high- and moderate-complexity testing in accordance with CLIA/TJC standards.
• Run and evaluate QC before releasing patient results; troubleshoot shifts, trends, and failures, and document corrective action.
• Recognize critical values, delta failures, and specimen-integrity issues; escalate and notify per policy.
• Operate, maintain, and troubleshoot analyzers; keep maintenance and temperature records inspection-ready.
• Participate in proficiency testing and corrective action.
• Execute method validation and verification studies for new assays.
• Maintain competency per CLIA (six-element assessment: semiannually in year one, annually thereafter).

Level II adds

• Own an instrument platform or QC program end-to-end, including Levey-Jennings review
• Review SOPs and flag needed updates; support validation studies under the Technical Supervisor/Laboratory Director.
• Train and document competency for new staff; serve as shift lead.
• Partner with R&D and software on LIMS rules, autoverification, and workflow automation.

Qualifications

Must-Haves (CLIA high-complexity testing personnel, 42 CFR §493.1489) — one of:

• Bachelor's, master's, or doctoral degree in medical laboratory science, clinical laboratory science, medical technology, or a chemical or biological science from an accredited institution; or
• Equivalent bachelor's-level education (120 semester hours including 24 hours of MLT courses, or 24 science hours with at least 6 chemistry and 6 biology) plus a NAACLS-accredited program or documented lab training in each specialty tested; or
• Associate degree in medical laboratory technology or a laboratory science (or CLIA-equivalent coursework) plus required laboratory training; or
• Completion of a 50-week U.S. military medical laboratory course and service as a Medical Laboratory Specialist.

Official transcripts or foreign-degree equivalency evaluation required before testing patient samples.

Level I: meets the above; new graduates welcome.

Level II: ASCP BOC MLS (or AMT MT) certification plus 2 years of high-complexity testing, ideally clinical chemistry and immunoassay.

All levels: available for the 6-day schedule on rotation.

Nice-to-Haves

• ASCP MLS/MLT or AMT certification. Level I hires must pass within 3 months of graduation; we will pay for the credentialing exam.
• Beckman Coulter AU/DxC/DxI, Roche cobas, or Abbott Alinity experience.
• Lab start-up, go-live, or TJC inspection experience.
• High-volume reference lab or automated line experience.
• Comfort with data: Excel, LIMS configuration, or basic scripting.

Location & Logistics

• On-site at our Burlington, MA lab, off I-95/Route 128 near Route 3. Free parking; reverse commute from Boston/Cambridge.
• Daytime 6-day operation (Mon–Sat); shift options include 8 hours weekday and 4 hours weekend.
• Pay: USD 35–42 per hour, placed by level and experience.
• Benefits: Paid certification and CE.
• Growth: clear MLS I → II → Lead → Supervisor path as we expand to additional sites.
• Post-offer health screening required (vaccination/TB per lab policy).
