Senior Fullstack Engineer

Senior / Staff Software Engineer

(Full-Stack Product Engineering | AI-Enabled Healthcare Technology)

Compensation:

• Senior: $170,000-$200,000 + early-stage equity

• Staff: $200,000-$240,000 + early-stage equity

Location: San Francisco, SoMa - office-first, 4-5 days per week with flexibility

The Company

We're partnering with a venture-backed healthcare technology startup building AI-enabled software for the emergency medical services industry.

Its platform helps ambulance providers recover revenue, improve clinical documentation, and connect fragmented operational workflows. With products already serving real customers, the company is now expanding its engineering team to support the next stage of product development and growth.

The Opportunity

This is an opportunity to join a small engineering team where you'll have genuine ownership over what gets built and how it works.

The company is hiring at Senior and Staff level, with scope determined by experience and independence. You'll work directly with the founder, technical leadership, and customers to build new products addressing significant operational problems in emergency healthcare.

The Role

We're looking for a product-minded full-stack engineer who can move comfortably between frontend, backend, databases, and infrastructure.

You'll help build and scale the company's core platform while developing new products for an industry still reliant on fragmented, disconnected systems. This is a hands-on engineering role with substantial autonomy, direct customer interaction, and responsibility for taking products from concept to production.

What You'll Do

• Build end-to-end products: Design, develop, and deploy full-stack applications using TypeScript, React, Node.js, and PostgreSQL.

• Own the complete development lifecycle: Take ambiguous problems from requirements gathering and architecture through implementation, testing, deployment, and iteration.

• Work directly with customers: Understand how ambulance operators and billing teams work, identify underlying problems, and translate their needs into effective product decisions.

• Develop new product capabilities: Build financial, documentation, and operational software that streamlines workflows and connects previously disconnected data.

• Improve existing systems: Design scalable APIs, robust data models, and maintainable services that support customer growth and new product launches.

• Shape technical decisions: Balance delivery speed, engineering quality, security, and long-term maintainability while contributing to the team's technical direction.

What You'll Bring

• Strong full-stack engineering experience: A track record of building and scaling production applications, ideally with TypeScript across frontend and backend.

• Early-stage startup experience: You've worked in environments where engineers own outcomes, work across multiple areas, and deliver without extensive supporting teams.

• End-to-end project ownership: You've independently taken meaningful products or features from initial requirements through production and subsequent improvements.

• Excellent product instincts: You ask why a feature is needed, understand how customers actually work, and challenge assumptions when there's a better solution.

• Clear communication and collaboration: You're comfortable engaging with nontechnical stakeholders, explaining complex decisions, and working closely with colleagues and customers.

• Sound engineering judgment: You write maintainable code, understand system design, can debug independently, and use AI development tools thoughtfully rather than relying on them blindly.

Experience in healthcare, regulated software, security, privacy, or public safety is valuable but not essential.

What This Role Requires

• Senior: Approximately 4+ years of relevant production software engineering experience, including substantial independent project ownership.

• Staff: Typically 6+ years of experience, with demonstrated ability to architect and deliver complex projects and drive broader technical decisions.

• TypeScript and full-stack capability: Recent TypeScript experience with the ability to contribute meaningfully across frontend, backend, and databases.

• Startup ownership and customer communication: Experience delivering production software end to end, navigating ambiguity, and communicating effectively with product stakeholders or customers.

• San Francisco presence: Willingness to work primarily from the SoMa office, typically four to five days per week.

Tech Stack

• Languages: TypeScript, JavaScript

• Frontend: React

• Backend: Node.js

• Database: PostgreSQL

• Cloud: Google Cloud Platform (GCP)

• AI: LLM API integrations, AI-enabled workflows, AI-assisted software development

The focus is on excellent product engineering rather than deep machine learning research or specialist agent development.

Why Join

• Build products with genuine impact: Your work helps emergency medical providers operate more efficiently, recover revenue, and continue serving their communities. You'll have opportunities to experience frontline workflows through ambulance ride-alongs and sponsored EMT training.

• Own meaningful technical and product decisions: Join early enough to influence architecture, engineering standards, customer solutions, and future product direction, with a substantial pipeline of greenfield development ahead.

• Competitive package and distinctive culture: Strong base compensation, early-stage equity, health, dental and vision coverage, a wellness stipend, and one week per quarter to work from anywhere. The company prioritizes in-person collaboration without an enforced 996 working culture.
