Metabolic Engineering Lead

Seed-stage climate biocatalysis company
Houston, TX, US
On-site · Lead

Build a microbial engineering platform for bio-based specialty chemicals used in industrial and consumer-product applications.

About the role

The company is developing a biological route to specialty chemical ingredients that are currently produced through petrochemical supply chains. As the founding biology lead, you will choose the first host-pathway strategy, build the DBTL workflow, and turn early chemistry and process assumptions into a strain-engineering plan. The company is still small, so the role includes hands-on scientific direction, vendor decisions, lab setup, and hiring input.

  • Team: Founding biology hire partnered with process and chemistry leaders
  • Stage: Seed-stage climate biocatalysis company with pilot customer design work underway
  • Reporting line: Chief Technology Officer
  • Experience: PhD with 8+ years in microbial strain engineering, industrial biotech, or metabolic engineering
  • Rhythm: Mostly onsite in Houston with flexibility around vendor and partner travel

Responsibilities

  • Select the first production host, define the lead pathway design, and decide which strain-engineering bets are worth building first.
  • Set up design-build-test-learn workflows that connect molecular biology, fermentation readouts, analytical chemistry, and clear go/no-go criteria.
  • Work with chemistry and process leaders so strain design, purification approach, feed strategy, and scale-up assumptions stay aligned.
  • Manage vendor selections, outsource early pipeline stages to CROs where appropriate, and configure foundational laboratory systems.

Requirements

  • PhD with 8+ years of industry experience in microbial strain engineering, metabolic engineering, industrial biotechnology, or a closely related field.
  • Track record engineering production pathways in yeast, E. coli, Bacillus, or relevant non-model microbial hosts.
  • Strong command of DBTL workflows, pathway bottleneck analysis, host/chassis trade-offs, and analytical methods used to judge strain performance.
  • Experience translating titer, yield, productivity, or pathway-bottleneck targets into practical fermentation, purification, or pilot-scale development plans.
  • Comfort owning vendor decisions, budgets, hiring plans, or lab buildout work in a small-company environment.

Preferred qualifications

  • Knowledge of gas fermentation or climate-tech specific biological utilization strategies.
  • Prior experience modeling flux pathways or employing 13C flux analysis metabolomics.

Technical stack

  • metabolic pathway design
  • chassis/host selection
  • genome editing
  • benchtop fermentation
  • titer/yield/productivity analysis
  • HPLC/GC-MS/LC-MS
  • flux analysis
  • techno-economic analysis
  • external CRO management

What we offer

  • Base salary: $175k - $215k
  • Equity / upside: Founding-level equity with clear participation in future refresh and leadership reviews.
  • Benefits: Medical, dental, vision, 401(k), flexible PTO, and relocation for a strong build-stage candidate.
