• Express recombinant proteins in cell‑free, bacterial, and yeast systems, in bulk and at high throughput.
• Purify proteins using chromatographic techniques such as affinity (Ni‑NTA, GST), ion exchange, and size exclusion chromatography.
• Analyze protein samples using SDS‑PAGE, Western blotting, BCA assays, and other biochemical methods.
• Develop and optimize activity and characterization assays for purified proteins, both in bulk and at high throughput.
• Maintain accurate and detailed lab records, including batch records and experiment documentation.
• Assist in troubleshooting expression or purification challenges and optimizing protocols.
• Prepare buffers and reagents, maintain reagent stocks, and ensure high laboratory standards.
• Collaborate closely with team members to achieve project goals and timelines.
• Comply with lab safety protocols and best practices in protein handling and biohazard management.

• Bachelor’s degree in Biochemistry, Molecular Biology, or related field with 2+ years of relevant laboratory experience.
• Hands‑on experience with molecular biology and protein techniques (academic or industry settings).

• Experience with cell‑free and cell‑based protein expression.
• Strong analytical and organizational skills with attention to detail.
• Ability to manage multiple tasks, work independently, and thrive in a collaborative team environment.
• Familiarity with lab information management systems (LIMS), electronic lab notebooks (ELNs), or related data‑management tools.
• Enthusiasm for learning and optimizing new techniques in a fast‑paced, innovative environment.

• Innovative Pioneer: You thrive in breaking new ground scientifically and are passionate about leveraging protein biochemistry to create transformative technologies.
• Collaborative Contributor: You excel in cross‑functional teams, readily share expertise, and value the input of colleagues.
• Inventive Problem Solver: You proactively identify challenges and rapidly ideate creative solutions.
• Mission‑Driven Individual: You are driven by an ambition to fundamentally change how biomolecules are synthesized and to meaningfully impact human health and biotechnology.
