Recognised as one of the top 20 startups across all categories worldwide at TechCrunch Disrupt 2024 - and backed by top-tier organisations like SOSV and Entrepreneur First - we’re pushing the boundaries of biochemistry and nanotechnology to revolutionize personalised health.

Founded by two seasoned engineers, we bring extensive experience in R&D, technical innovation, and commercial strategy to transform the way people monitor their health. Our mission is bold: to revolutionise health management by delivering clinical-grade data directly to individuals, wherever they are.

We’re seeking driven innovators to join us in pushing the boundaries of biosensing and health tech, making personalised health monitoring a reality for everyone. To achieve this ambitious vision, we’re assembling the best team in the world - dedicated to turning cutting-edge science into life-changing, real-world solutions.

About this Role

We’re looking for a Research Associate to help drive aptamer discovery and early-stage biosensor R&D at Level Zero. Working closely with R&D and sensor design leadership, you’ll run SELEX campaigns for small-molecule targets, execute core wet-lab workflows (affinity chromatography, qPCR, gels, nucleic acid purification, NGS), and combine experimental rigor with oligo design and bioinformatic analysis to identify and validate top aptamer candidates.

What you'll do

  • Conduct SELEX experiments for small molecule targets to identify new aptamers, involving wet lab bio/chem processes including affinity chromatography, qPCR, gel electrophoresis, nucleic acid purification, and next-gen sequencing.
  • Conduct nucleic acid oligo design and bioinformatic analyses to identify aptamer candidates
  • Validate aptamer binding using methods such as Isothermal Titration Calorimetry (ITC), Surface Plasmon Resonance (SPR), plate-based fluorescence assay, melt curve analysis and other methods.
  • Contribute to early-stage R&D, and collaborate with sensor design leadership to define and refine future directions

    • What You Bring

    The ideal candidate must have:

  • A Bachelors degree or higher with at least 2 years of industry experience (full-time wet lab)
  • Proficiency in molecular biology and chemistry lab workflows such as affinity chromatography, qPCR, gel electrophoresis, nucleic acid purification, and binding assays.

    • Nice to have:

  • Knowledge or experience in the handling and study of hydrophobic compounds (e.g., hormones), the handling and study of bio-fluids, and the development of simulated bio-fluid model solutions, biosensing principles,
  • Bioinformatics experience, Bash, Python, R languages, next-gen seq data processing, sequence motif analysis, nucleic acid 2D-prediction, or nucleic acid design (e.g., primer design).
  • Knowledge or experience next-gen sequencing and Illumina systems, nucleic acid synthesis and purification.
  • Knowledge or experience with biophysical characterization, ITC, SPR, CD spectroscopy, biosensing, fluorescence characterization approaches, or macromolecular structural characterization using NMR, SAXS, docking or MD simulations
  • Prior work in a start-up or small company environment

    • Who You Are

    We value culture as much as we value technical expertise, creating an environment that’s equal parts collaboration, curiosity, and fun.

    We’re a fast-paced, mission-driven young team on a quest to make a lasting impact, fueled by uncompromising integrity, unwavering support for one another, and the thrill of exploring uncharted territories.

    If our vision excites you, here are the qualities we look for:

  • You live and breathe integrity, tackling challenges with honesty and transparency.
  • You’re a self-starter who loves diving into the unknown, collaborating on complex problems, and taking full ownership of results.
  • You excel at open, clear communication and see every piece of feedback as a springboard for growth—especially in a science and data-focused environment.
  • You’re motivated by creating real impact, particularly when it comes to advancing human health.
  • You strike a balance between independence and collaboration, knowing when to seek support or invite others to join in.
  • You’re confident in defending your ideas, while also valuing respectful, constructive debate as a path to better solutions.
  • You thrive in the dynamic atmosphere of a startup, constantly evolving your skill set and fearlessly applying what you learn.

    • What we offer

  • A full-time role with a competitive salary and equity options, reflecting our value in your expertise and potential.
  • An environment where you’ll collaborate directly with the founding team at a leading biosensor startup, gaining access to industry experts and thought leaders.
  • The chance to grow with us, including ample opportunities for leadership, career advancement, and exploration.
  • Travel to New York and other potential sites for R&D purposes.
  • The excitement of working on cutting-edge technology, shaping strategic decisions, and driving innovation at an early-stage venture alongside a superstar team.
