About Amigo

Amigo partners with healthcare organizations to deploy robust AI infrastructure that directly serves patients and providers. Our agents handle clinical workflows and patient engagement across the entire journey: pre-visit intake, care navigation, post-visit care plans, patient monitoring, and more.

We own outcomes, not just delivery. For our customers, we're responsible for agent performance: clinical safety, continuous improvement, measurable patient outcomes. Agents operate autonomously within bounded clinical domains, with clear scope and handoff protocols. That scope expands as we validate performance across populations.

We're backed by Tier 1 investors like General Catalyst, GSV Ventures, SVA, and CohoVC. Our work is validated with leading academic medical institutions. Our agents have reached 3M+ patient encounters and are on track to 10x this year.


About this role

As a Staff Software Engineer (Backend) at Amigo, you'll own the technical direction of the backend systems that power our agent platform at scale. You'll architect high-performance services handling millions of conversations, drive engineering standards, and make critical decisions on system design for real-time inference, LLM orchestration, and healthcare integrations.

You'll mentor engineers, shape technical culture, and ensure we maintain elite engineering standards as the team grows. These systems handle sensitive patient data and support clinical workflows—correctness and reliability are non-negotiable.


What you'll do

  • Own technical architecture for backend systems including real-time inference, multi-LLM orchestration, and conversation handling

  • Drive engineering standards for code quality, testing, observability, and incident response

  • Architect high-performance services that handle concurrent requests at scale with predictable latency

  • Design integration patterns for EHR systems and legacy healthcare infrastructure

  • Own the approach to distributed systems challenges: consensus, replication, fault tolerance

  • Make build vs. buy decisions and evaluate technical tradeoffs across the backend stack

  • Design APIs and service-oriented architectures that power the agent platform

  • Architect secure data handling for sensitive healthcare information with proper access controls

  • Own monitoring, logging, and observability architecture for backend services

  • Mentor engineers and establish patterns that raise the bar for the entire team

  • Collaborate with platform, infrastructure, and agent teams to ensure system-wide coherence

  • Define reliability targets and drive operational excellence across backend systems


What we're looking for

  • 7+ years of production backend engineering experience, with significant time at elite engineering organizations

  • Expert-level experience with backend development in Python, Go, or similar languages

  • Proven track record designing distributed systems that scale—you've built and operated high-traffic production services

  • Deep experience with concurrency programming, including threads, async operations, and parallelism

  • Strong understanding of distributed systems concepts (consensus, replication, partitioning) and when to apply them

  • Experience with message queuing systems, event streaming, and async communication patterns at scale

  • History of establishing engineering standards and mentoring engineers

  • Extremely high standards for code quality, reliability, and operational excellence

  • Both execution-oriented and defensive-minded: you ship fast while anticipating failure modes

  • Deep knowledge of database systems, both SQL and NoSQL, and their scaling characteristics

  • Excellent written and verbal communication across engineering and executive stakeholders


Nice to have

  • Experience with healthcare systems, EHR integrations, or HIPAA compliance at scale

  • Background with real-time inference systems or LLM orchestration

  • Experience with high-throughput, low-latency system design

  • Track record building and scaling engineering teams

  • Understanding of observability and monitoring in distributed environments

Our Core Values

  1. Patients Win, We Win

    If patients aren't getting better care, we haven't earned the right to scale. Every internal decision gets pressure-tested: does this make patients' lives better? If we can't draw the line, we question why we're doing it.

  2. High Standards, High Care

    We hold a high bar for the team because patients are counting on us to get this right. But high standards only work with genuine investment in each other. You can take risks, admit mistakes, and challenge ideas—not despite our standards, but because of them.

  3. Thoughtful Urgency

    We move fast by default, but speed without judgment is recklessness. The discipline is knowing which decisions are reversible vs. not. In healthcare AI, the companies that win will be fast everywhere they can be and careful everywhere they must be. We build the muscle to do both.

  4. Intensely Measured

    We instrument patient outcomes, provider ROI, system performance, and clinical accuracy. But data without action is surveillance. Every metric should have an owner, a threshold, and a response plan. If we're measuring something but never acting on it, we stop measuring it.

Who Builds With Us

  • Low ego: Politics and territory don't interest you. The best ideas win, regardless of who has them.

  • Direct: You say the hard thing, challenge ideas openly, and commit fully once decided.

  • High agency: You thrive on trust rather than instruction. When you see something is broken, you fix it. You don’t file tickets and wait for someone else.

  • Bar of excellence: You hold yourself to a bar most people wouldn't, and you want teammates who do the same.

  • Skeptical: You push back on rules that don’t make sense and question assumptions that haven’t earned their place.
