In Vivo Pharmacology (Senior Research Assistant - Senior Associate Scientist Level)

California Institute of Technology & Howard Hughes Medical Institute | Elowitz Lab

Full-time | Pasadena, CA (onsite) | 1-year term (renewable) | Start: March-April 2026 (flexible)

Our team in the Elowitz Lab at Caltech/HHMI is engineering therapeutic protein circuits, a new cancer-treatment modality at the intersection of synthetic biology and oncology. We're looking for an in vivo oncology scientist (Senior Research Assistant to Senior Associate Scientist) to help expand and run the program's translational in vivo engine. The role starts in an academic setting, with the option to transition into an early-stage startup in 2027.

Why therapeutic circuits?

Cancer therapies face a fundamental trade-off between effectiveness and precision, driving off-target toxicity, recurrence, and resistance. Therapeutic protein circuits address this by directly rewiring oncogenic mutations to cell death. Delivered as mRNA in lipid nanoparticles, these engineered proteins can distinguish cancer from normal cells and have shown tumor suppression in vivo. By design, these circuits "sense and kill" rather than inhibit. This mechanism makes them independent of oncogene addiction and less susceptible to resistance than most targeted therapies, potentially enabling a new generation of highly potent and specific cancer medicines.

Why join us now?

Over the past decade, our team has built and de-risked the therapeutic circuit platform. As we move toward a spinout, this is a rare chance to join at the inflection point where cutting-edge research becomes an early commercial program. You'll be part of a small, fast-moving, startup-minded team, helping build what could become a future cancer therapy.

What you'll do:

• Own and independently execute end-to-end in vivo oncology studies from tumor initiation through decision-grade analysis and reporting.
• Partner with the team to design studies and translate study plans into executable protocols.
• Execute and continuously refine a portfolio of in vivo models, including subcutaneous xenografts, orthotopic tumor models, and genetically induced models (including HTVi-initiated systems); establish and qualify new models.
• Perform hands-on mouse work, including tumor engraftment/initiation, dosing (IV, PO, IP, IT), monitoring, tumor measurements, necropsy, and tissue collection with rigorous documentation.
• Run longitudinal readouts such as IVIS bioluminescence imaging and blood sampling; perform terminal procedures, including terminal blood collection and perfusion.
• Lead downstream sample analysis workflows: process tissues for flow cytometry, IHC/IF, or spatial readouts (e.g., seqFISH) and coordinate tasks with the team.
• Conduct basic data and statistical analysis; build clear figures and concise summaries to inform study decisions and next steps.
• Support IACUC protocols and amendments; uphold high standards for animal welfare and EH&S compliance.
• Improve how we operate: upgrade our workflows/SOPs and support mentoring/training.

What qualifications are we looking for?

• Bachelor's degree in life sciences (or related) with 4-8 years relevant in vivo experience, or Master's degree with 2-6 years relevant in vivo experience
• Strong hands-on in vivo experience, including mouse handling, HTVi, common dosing routes (IV, PO, IT), and endpoint procedures (necropsy, tissue collection).
• Demonstrated ability to build, own, and optimize workflows and SOPs.
• High rigor, strong documentation habits, and attention to detail.
• Familiarity with IACUC protocols and EH&S regulations; commitment to humane animal work.
• Proactive communicator; ownership mindset; collaborative teammate.

Nice to Haves:

• Experience across multiple tumor models (subcutaneous, orthotopic, genetically induced).
• Prior experience in an early-stage startup (Competitive salary and Caltech benefits; compensation commensurate with experience. If the program transitions into a startup and you transition with it, competitive industry salary, benefits, and equity options may be available.

We are looking for a deeply committed Technical Program Manager who has successfully shipped cutting-edge AI models in aerospace & robotics, managed relationships with customers, has exceptional software engineering management knowledge, and thrives in fast-paced, unstructured environments.

What you’ll do

• Contribute hands-on to AI model and product development, including pretraining, fine-tuning, evaluation, and deployment
• Translate product goals into actionable roadmaps
• Plan and execute product development initiatives, owning timelines and delivery
• Influence org structure and hiring
• Mentor team members

Qualifications

• Master’s degree or PhD in Engineering, Computer Science, Mathematics or related field, or equivalent experience.
• 4+ years of experience in technical program management or applied AI/ML roles, ideally in high-growth startups or fast-paced research orgs.
• Expertise with one or more of computer vision, vision-language models, or foundation model development.
• Experience working with academic / PhD-level researchers
• Strong track record of turning ambiguous technical goals into successfully shipped models, features, tools, or systems.
• Preferred: 1+ years robotics experience

Our team

Our team is composed of AI pioneers and leaders from Google DeepMind, Shield AI, Caltech & MIT. Several of us are repeat founders, with deep commercialization insights across multiple enterprise segments. We enjoy long, deep ideations around entirely unexplored AI use cases in autonomy.

Who you are

• Learn-it-all, not know-it-all: you have an innate curiosity for all things intellectual, and it’s something you can’t turn off. You obsess over finer details others miss.
• High intensity: you thrive in a high-stakes environment, and are driven by an innate obsession, not by others.
• Fast learner: you gravitate toward learning new things, and often find yourself learning more quickly than everyone around you.
• Driven by discomfort: you enjoy leaving your comfort zone and challenging yourself
• Creative: track record of solving hard problems with solutions worthy of academic papers
• Educator: you take pride in your ability to communicate complex topics clearly and have excellent speaking and writing skills.
• Zero ego: you don’t just take feedback, but see it as a gift. You don’t wait until feedback is given, but solicit it with every opportunity.
• Founder mentality: you roll up your sleeves to help solve the most pressing problem on a given day, even if it has nothing to do with this job post.
