Docflow is a platform that builds AI agents that run the back office for speciality healthcare providers.
The Role
Build and operate the platform that enables AI agents to develop, deploy, run, monitor, and safely update healthcare automations. Responsibilities include distributed runtime infrastructure, isolated cloud sessions, deployment and versioning, observability, durable workflows, security guardrails, agent-facing APIs and CLIs, supervision interfaces, and production incident response. The role requires strong reliability instincts, cloud infrastructure expertise, typed programming, and experience using AI coding agents.
Summary Generated by Built In

Docflow builds AI agents that run the back office for healthcare providers. Our automation handles the work that buries their teams: document intake, prior authorizations, order entry, and payer portal workflows. Customers start with a paid pilot, see real work getting done within weeks, and expand from there.

We’re a small, scrappy, AI-native founding team, and we’re growing fast. A year ago, agents opened none of the pull requests merged into our codebase. Last month, they opened more than half. Building the system that makes that safe is now the most important engineering work we do. That’s why we’re hiring you.

The Role

You won’t be writing our automations. You’ll be building the system that writes them, runs them, and keeps them working.

Take browser automation. We run hundreds of automations against payer and provider portals we don’t control, following business rules that change whenever a payer or a customer does. Portals get redesigned overnight. A payer adds a step. A customer changes how they want an order handled. No team of people could keep up with that by hand, so agents do most of it. They investigate failures, trace them to a root cause, write the fix, review each other’s code, confirm the fix worked in production, and finish stuck work themselves in a live browser when an automation can’t.

Your job is to build the engineering system all of that happens inside: the runtime agents work in, the pipeline their changes ship through, the observability that shows them and us what’s actually happening, and the guardrails that keep an agent’s change from reaching a customer unchecked. Browser automation is just one example. The same system supports document extraction, eligibility checks, outbound calling, and whatever we build next.

This is infrastructure engineering: distributed systems, durable execution, deployment and versioning, observability, reliability, and security. What’s different is who uses what you build. Your users are agents and the people who supervise them, and agents are demanding users. They work fast, they work in parallel, and they will find every ambiguity in an interface and every gap in a guardrail.

We’re hiring two engineers. This is the one that builds the platform. Our other engineering role, Product Engineer, owns what customers experience: the tools built on top of the platform and the product they use every day. If you’d rather build the system every workflow and every agent depends on than tune any one of them, this is your seat.

We write strictly typed TypeScript in a functional style: algebraic data types and discriminated unions, state reified as explicit values rather than implied by scattered flags, and exhaustive handling the compiler enforces. That matters more when agents write much of the code, not less. When an agent adds a new case, the compiler walks it to every place that has to handle it.

Because we handle protected health information, reliability and care are not optional. An agent moves faster than a person, and so do its mistakes. A big part of this job is making sure the system catches them first.

What You’ll Do
  • Build the runtime our agents work in: isolated sessions on on-demand cloud machines, warm pools, sandboxed browsers, and tightly scoped access to the credentials and portals each job needs

  • Evolve the loop that carries a problem from first report to verified fix: investigation, root cause, code change, automated review, human approval, deploy, and verification against real business outcomes in production

  • Own deployment and versioning, so a workflow change can ship in under a minute, run exactly the code it was built with, and roll back cleanly without anyone watching

  • Build the observability that makes a highly autonomous system legible: metrics, alerting, dashboards as code, execution traces, and provenance that ties every result to the build that produced it

  • Treat agents as first-class users of everything you build, with CLIs, APIs, and error messages clear enough that an agent can diagnose a problem without a person translating

  • Keep long-running distributed workflows correct under failure: idempotent, resumable, bounded, and safe to replay across deploys

  • Build the surfaces where people supervise agents, such as approval queues, code review, and live views of what’s running

  • Run production: debug the incident, write the postmortem, and fix the class of problem rather than the one instance

  • Work directly with our CTO to set the engineering standards the team, human and agent, grows into

What We’re Looking For

Must have:

  • Strong professional experience building and operating production systems. We care more about what you’ve built and kept running than a years-of-experience number, though in practice this usually means several years in the field.

  • Real distributed systems instincts. Race conditions, retries, idempotency, backpressure, cancellation, and partial failure are things you think about by default, not after a bug.

  • You’ve owned the reliability of something that mattered: been paged for it, debugged it from metrics, logs, and traces, and fixed the root cause instead of the symptom.

  • Hands-on experience with cloud infrastructure and deployment, including CI/CD, containers, and shipping and rolling back changes safely on platforms such as AWS, GCP, or Azure.

  • Deep proficiency in a statically typed language. TypeScript is what we write every day, but strong Go, Rust, or similar is just as welcome if you’re ready to get strong in TypeScript quickly. Either way, you use the type system to make invalid states unrepresentable rather than reaching for escape hatches like any or unsafe casts.

  • You already build with AI coding agents such as Claude Code, Codex, or Cursor every day, and you have clear opinions about where they break down and what the system around them should do about it.

  • Comfort across the stack. Most of this role is backend and infrastructure, but you’ll also build the interfaces people use to supervise agents.

  • High standards for readable, maintainable code and a low tolerance for needless complexity.

Preferred:

  • A strictly typed, functional style: algebraic data types and discriminated unions, exhaustive matching, state reified as explicit values, and pure logic kept apart from side effects. Time in languages built around these ideas, such as Haskell, OCaml, F#, Rust, or Scala, counts

  • Experience with durable execution or workflow orchestration, such as Temporal

  • Experience building internal developer platforms, build and release systems, or CI/CD infrastructure that other engineers depended on

  • Experience running fleets of containers or VMs, including pooling, autoscaling, and graceful rollouts

  • Experience with observability tooling such as Prometheus, Grafana, or OpenTelemetry

  • Experience building LLM agents in production, including tool design, evaluation, or guardrails

  • Experience in regulated or security-sensitive domains such as healthcare or fintech, and handling sensitive data

  • Based in Los Angeles, or ready to be

Compensation and Benefits
  • Base salary of $150,000 to $185,000 depending on experience

  • Founding-team equity

  • Health insurance

Skills Required

  • Hands-on experience with cloud infrastructure and deployment, including CI/CD and containers
  • Experience shipping and safely rolling back changes on AWS, GCP, Azure, or similar cloud platforms
  • Deep proficiency in a statically typed language
  • Willingness to become proficient in TypeScript if primarily experienced in another statically typed language
  • Daily experience building with AI coding agents such as Claude Code, Codex, or Cursor
  • Comfort working across the stack, including backend, infrastructure, and supervisory interfaces

What We Do

Docflow builds AI agents that run the back office for specialty healthcare providers — the organizations that get equipment, supplies, and ongoing care to patients outside the hospital. The work that buries these teams is not clinical. It is document intake, prior authorizations, order entry, eligibility and benefits checks, and endless hours inside payer portals. A single patient order can mean a faxed referral to read and classify, a prior authorization to submit to one of a dozen portals, a follow-up a week later to find out whether it was approved, and a stack of updates typed back into the provider's system of record. Multiply that by thousands of orders a month and you have entire departments doing work no one went into healthcare to do. Our agents do that work. They log into the same systems a person would — the provider's system of record and dozens of payer and utilization-management portals — read the documents, fill the forms, and write the results back. Every action is recorded: a screenshot and a full session trace for every step, so a provider's team can audit exactly what was done on every order. When an agent hits something it should not decide alone, it stops and asks a human instead of guessing. We are HIPAA compliant and handle PHI for every customer we serve. Customers start with a paid pilot on a single workflow, see real orders getting processed within weeks, and expand from there. Most of our growth comes from customers handing us their next workflow. We are a small founding team based in North Hollywood, Los Angeles. We are revenue-funded, our recurring revenue quadrupled over the last five months, and our pipeline is bigger than we can currently work.

Why Work With Us

We are revenue-funded and small enough that your work is visible the day you do it. Recurring revenue quadrupled in five months and our pipeline is bigger than we can work. You'll work directly with the founders, own a function outright rather than a slice of one, and watch AI do real work in a corner of healthcare nobody has automated yet.
