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 Senior Software Engineer (Backend) at Amigo, you'll build the core backend infrastructure that powers our agent platform at scale. You'll develop high-performance services that handle millions of conversations per month, focusing on concurrency, reliability, and clean system design. This role requires strong concurrency programming skills and curiosity for finding good solutions to complex technical challenges.

What you'll do

• Design and implement high-performance backend services handling concurrent requests at scale

• Build robust APIs and service-oriented architectures that power our agent platform

• Develop systems with concurrency patterns to maximize throughput and reliability

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

• Work with distributed systems concepts like consensus, replication, and fault tolerance

• Build resilient services that gracefully handle failures and maintain high availability

• Optimize system performance through careful concurrency design and resource management

• Solve complex backend challenges with simple, maintainable solutions

• Implement monitoring, logging, and observability for backend services

• Collaborate with platform teams to ensure integration across services

• Design systems that scale horizontally while maintaining data consistency

• Contribute to architectural decisions that shape our backend infrastructure

What we're looking for

• 4+ years of production-level experience with backend development languages

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

• Experience developing large-scale distributed systems or working with distributed architectures

• Background working on SaaS platforms or with Service-Oriented Architectures

• Experience with cloud platforms and container orchestration technologies

• Strong understanding of security best practices and experience with systems handling sensitive data

• Understanding of distributed systems concepts (consensus, replication, partitioning) without necessarily having built foundational frameworks

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

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

• Curiosity for elegant solutions and clean, maintainable code

• Strong debugging skills for concurrent and distributed systems

• Strong problem-solving abilities with focus on system reliability and performance

Nice to have

• Experience in healthcare, finance, or other regulated industries

• Understanding of observability and monitoring in distributed environments

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

• Background with complex data processing systems

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.
