About Us

At Isospec, we’re building a new standard for molecular identification to unlock patient-centric drug development and diagnostics. You will be a key driver of the "lab engine" that turns partner samples into robust, decision-ready insights—fast, reproducibly, and at scale.

Your Impact

Rigorousness: You are the primary steward of our analytical precision. By mastering our workflows, you ensure that every microliter of a partner's sample is processed with the rigor required for a world-class analytical lab. Driving Laboratory Excellence: By managing the day-to-day operation and maintenance of our LC-MS platforms, you ensure the sensitivity and reproducibility required for every analysis. Scaling Innovation: You will work alongside senior scientists to translate R&D methods into high-throughput screening workflows, helping us scale from small identification projects to massive clinical cohorts. Shaping a Startup Culture: In our fast-paced environment, your technical expertise and proactivity will directly influence our internal SOPs and the efficiency of our "omics" pipelines.

What You Will Do

As a Laboratory Technician, you will be the technical engine of our high-throughput LC-MS facility. You will support in developing and executing cutting-edge "omics" workflows – from complex sample preparation to the operation and maintenance of state-of-the-art mass spectrometry platforms. This role is ideal for a detail-oriented individual who thrives in a fast-paced environment and enjoys transitioning procedures from research and development into solid analytical methods.

  • Wet-Lab & Sample Prep: Preparation of stock solutions. Execution of complex extraction including liquid-liquid extraction, solid-phase extraction and derivatization protocols for metabolomics, lipidomics, glycomics, and proteomics.
  • LC-MS Operation: Method development and optimization. Manage the daily operation of high-resolution Mass Spectrometry systems and Liquid Chromatography (UPLC) platforms.
  • Automation Integration: Operate and troubleshoot semi-automated liquid handling systems for the screening of large-scale studies.
  • Routine Maintenance: Perform guided preventive instrument maintenance to ensure peak instrument performance.
  • Workflow Execution: Work independently, and support staff to translate research goals into reproducible laboratory workflows, ensuring rigorous data quality and sample integrity.
  • Inventory & Documentation: Maintain detailed electronic lab notebooks (ELN) and manage the logistics of reagent and consumable stocks.

Skills and Qualifications

Essentials

Immigration

Valid work permit for Switzerland required.

Education:

  • Apprenticeship (CFC): Laborantin/-e en Chimie with a strong focus on analytical chemistry.
    • Note: Candidates with a CFC and a Maturité Professionnelle are highly encouraged to apply.
  • Higher Education: Bachelor’s or Master’s degree from a HES (Haute École Spécialisée), such as HEIA-FR or HES-SO (e.g., Life Technologies), or a University degree in a related field.
  • Professional Experience: Ideally 2–5 years of experience in an analytical laboratory environment.
    • Proven track record in a regulated or high-throughput environment (industry or advanced academic core facility).

Technical Experience:

Sample preparation, and hands-on experience with Liquid Chromatography and high resolution mass spectrometry (Orbitrap, QTOF, or TQD).

Omics Knowledge

Familiarity with proteomic, lipidomic, and  metabolomic workflows.

Soft Skills

Good analytical and organizational skills. Strong troubleshooting mindset, "can-do" attitude regarding equipment maintenance, and extreme attention to detail.

Language

French and English (mandatory): Good technical reading and speaking skills in English are essential, as most instrument software, SOPs, and scientific literature in the LC-MS field are in this language. The company language is English.

Nice To Have

Automation

Experience with liquid handling robots (e.g., Hamilton, Waters Andrew+, or Agilent Bravo) is highly desirable.

Software:

Good computer skills, and experience in Laboratory Information Management Systems, Microsoft Office. Vendor software (Agilent environment  is desirable), Skyline

Culture and Perks

  • Impact that matters: Help solve one of the most difficult bottlenecks in translational science, trustworthy molecular ID and actionable biomarkers.
  • Build the blueprint: Your systems and standards will define how next-gen metabolomics operates at scale.
  • Elite collaborators: Work with leading hospitals, biotech, and pharma on programs that change patient outcomes.
  • Ownership & growth: High autonomy, rapid learning, and a direct line from your work to patient benefit.
