AI Engineer at 3Y Health - Remote from Argentina — Columbus
Traveler-Friendly Insight
Remote-Friendly, Distributed Team: 3Y Health explicitly states the team is distributed across time zones, with decisions made asynchronously via specs, PRs, and tickets. This is a strong async-positive signal — no mention of mandatory fixed hours or core overlap windows, though healthcare operations contexts may occasionally require some US business hours responsiveness.
Timezone Considerations: With the role hinted at Argentina (ART, UTC-3), overlap with US Eastern time (UTC-4/5) is naturally strong — typically 1–4 hours of difference. This is excellent for a US-focused healthcare company without requiring you to work odd hours.
Visa & Location Flexibility: Argentina has a Digital Nomad Visa ("Nómade Digital") allowing remote workers to live and work legally for up to 6 months, renewable. Neighboring countries like Uruguay and Colombia (Medellín) also offer nomad-friendly options with similar timezone alignment.
Cost of Living vs. Compensation: No salary is disclosed, but senior engineering roles at US healthtech startups for LATAM talent typically range $60K–$120K USD annually. At that range:
- Buenos Aires: Very comfortable — monthly expenses ~$1,200–$1,800 USD for a good quality of life
- Medellín, Colombia: Excellent value — ~$1,000–$1,500/month
- Lisbon, Portugal: Pricier at ~$2,500–$3,500/month, but still feasible at senior pay
No travel-specific perks (coworking, equipment stipend) are mentioned in the posting — worth asking about during interviews.
About 3Y Health
3Y Health is building the operating system for healthcare practices — an AI-native platform that helps clinicians start, run, and grow their practice. We work as a managed services organization (MSO): along with the software, our operations team runs the back office for the clinics we partner with, including billing, insurance, and compliance. We currently serve applied behavior analysis (ABA) therapy practices and are expanding into speech, occupational and physical therapy, and psychiatry.
About the Role
Members of Technical Staff own features end to end. You'll work with the clinicians and operators who use what we build, scope the problem, design and build the solution across the stack, deploy it, and follow how it performs in production. Our engineering team is flat, with no sub-teams, so you'll work across the whole platform. We build with AI coding agents every day and expect you to do the same.
What You'll Do
- Design and build AI agents and automated workflows for clinic operations, such as insurance benefits verification, prior authorizations, patient intake, claims, and clinical documentation
- Build features for clinicians, patients and families, and our internal operations team, on web and mobile
- Take ambiguous problems from 0 to 1, working with operators and clinicians to define the problem, write the spec, and ship a first version
- Design the services, data models, and APIs behind your features and manage the infrastructure as code
- Own your services in production: deployments, monitoring, and incident response
- Write evals for model-facing features and track the metrics of the workflows you ship
- Work with protected health information (PHI) safely, with least-privilege access, no PHI in logs, and auditable changes
- Build and maintain the skills, plugins, MCP integrations, and review bots our engineers use with Claude Code and Codex
Our Stack
- Backend: Python (primary language for new services), Kotlin with Hasura (GraphQL) on our established platform, plus TypeScript (NestJS) and some Go
- Frontend & Mobile: React, Next.js, React Native
- Data: PostgreSQL (including pgvector), Snowflake
- Workflows & Contracts: Temporal, gRPC/Protobuf
- Infrastructure: AWS (ECS Fargate, RDS), Terraform, GitHub Actions, Datadog, LaunchDarkly
- AI: Claude and OpenAI models, Claude Code and Codex, with our own skills, plugins, MCP integrations, and an AI code-review bot
Must-Haves
- 5+ years of experience building and shipping production software
- Recent, hands-on experience using or building AI harnesses: the layer around a model or coding agent (project instructions, tools and MCP servers, skills, hooks, subagents, evals) — not only calls to a model API. You can show what you set up or built.
- At least one personal project you built and published on the web, live and usable by anyone — ideally a SaaS with payments working (e.g., Stripe). Share the link when you apply.
What We're Looking For
- A track record of owning products or features end to end, from an unclear problem to a system people depend on
- Strong full-stack skills in Python and TypeScript, with experience across frontend, backend, databases, and cloud infrastructure
- Comfort working in a large, established codebase
- Hands-on experience building with LLMs, including tool use, agent orchestration, structured outputs, retrieval, and evals (LangGraph, an agents SDK, or similar)
- Daily use of AI coding agents such as Claude Code, Codex, or Cursor. You know how to set them up for a codebase (project instructions, skills, MCP servers, hooks, subagents), run several tasks in parallel, and review their output carefully. If you haven't heard of Claude Code, this role is likely not a fit.
- Good product sense and the ability to make solid UI decisions without a dedicated designer, using our component library
- High agency: you unblock yourself, look for context, and ask questions when you need to
- Clear written communication. The team is distributed across time zones and most decisions happen in specs, PRs, and tickets.
Nice to Have
- Experience in healthcare or another regulated industry (HIPAA, payer and claims workflows, EHR integrations, HL7/FHIR)
- Temporal or another durable workflow engine
- React Native
- Running LLM evaluations or safety checks on model output in production
- Having built your own agent harness, MCP server, or plugin for a coding agent
- Open-source work or internal tools that other people use
If you meet all the must-haves and most of the rest, we'd like to hear from you, even if you don't check every other box.
