    The Opportunity

    We’re looking for a Technical Co-Founder and AI-Native Engineering Leader to build the next generation of healthcare technology.

    This is a hands-on founding role for someone who wants to build from zero—not inherit an established engineering organization.

    The company is focused on using the latest advancements in AI agents, agentic systems, and modern software infrastructure to solve meaningful problems within healthcare. You’ll help define the technical vision, build the initial product, establish the engineering foundation, and ultimately grow the organization around it.

    We are looking for a builder first and engineering leader second.

    What You’ll Do

    • Own the technical strategy, architecture, and engineering roadmap from the earliest stages of the company.

    • Build and ship the initial product alongside the founding team.

    • Design AI-native products using modern LLMs, agents, orchestration frameworks, retrieval systems, and emerging agentic infrastructure.

    • Rapidly prototype, test, and iterate based on customer feedback.

    • Make pragmatic technical decisions that balance speed, scalability, reliability, and product-market fit.

    • Establish the engineering culture, development practices, and technical standards of the company.

    • Recruit and build the engineering organization as the business scales.

    • Work directly with customers, operators, and healthcare stakeholders to understand problems and translate them into products.

    • Partner with the founding team on product strategy, fundraising, hiring, and company-building.

    What We’re Looking For

    You’ve Built From 0 → 1

    This is the most important qualification.

    We’re looking for someone who has personally helped build a company or product from its earliest stages into a meaningful commercial business.

    Minimum expectation: experience helping grow a product or business from approximately $0 to $2M+ in ARR.

    You understand what it means to:

    • Build before every requirement is known.

    • Talk directly with customers.

    • Ship quickly.

    • Throw away things that don’t work.

    • Find product-market fit.

    • Make technical decisions with limited resources.

    • Turn early prototypes into production systems.

    You’re AI-Native

    You’re not simply adding AI features to traditional software.

    You actively experiment with and build around modern AI systems, including areas such as:

    • Large Language Models

    • AI Agents

    • Agentic Workflows

    • Tool Calling

    • Retrieval and RAG

    • Model Evaluation

    • Structured Outputs

    • Multi-Agent Systems

    • Human-in-the-Loop Systems

    • AI Observability and Reliability

    You understand that the AI development stack is evolving quickly and are constantly experimenting with new models, frameworks, and approaches.

    You’re Still a Builder

    You may have been a CTO, VP of Engineering, Founding Engineer, or Engineering Leader—but you still want to write code.

    This is not a role where you manage a large engineering organization from day one.

    You should be comfortable:

    • Architecting systems.

    • Writing production code.

    • Prototyping new ideas.

    • Debugging.

    • Deploying.

    • Talking to customers.

    • Recruiting engineers.

    • Making product decisions.

    Some days you'll be thinking about company strategy. Other days you'll be deep in the codebase.

    Ideal Background

    We’re especially interested in people who have:

    • Founded or helped build an early-stage technology company.

    • Been among the first engineering hires at a successful startup.

    • Served as a technical founder, founding engineer, CTO, or senior technical leader.

    • Built and commercialized AI-powered products.

    • Created products used by real customers—not just prototypes or research projects.

    • Experience operating within high-growth startup environments.

    • Strong product instincts in addition to technical depth.

    Healthcare experience is valuable, but startup-building ability and technical horsepower matter more than healthcare pedigree.

    Why This Opportunity

    You’ll be joining at the point where the biggest technical and product decisions have yet to be made.

    There is no legacy architecture to maintain and no massive engineering organization slowing down decision-making.

    You’ll have the opportunity to help determine:

    • What gets built.

    • How it gets built.

    • Which technologies we use.

    • How AI agents become part of the product architecture.

    • Who joins the engineering team.

    • How the company approaches product development.

    • What the engineering culture becomes.

    With $1M–$3M of seed funding, competitive cash compensation, and meaningful founder-level equity, this is an opportunity to build a company—not simply join one.

    Compensation

    Base Salary: $150,000–$200,000
    Equity: Meaningful co-founder-level equity package

    Final compensation will depend on experience, technical background, previous startup success, and level of involvement in building the company.
