Synthesis Health

Who We Are

We’re a mission- and values-driven company with tremendous dedication to our customers. Our 100% remote team is dedicated to a common goal – to revolutionize healthcare through innovation, collaboration, and commitment to our core values and behaviors. About the Opportunity We are looking for a Principal Platform Engineer to serve as a hands-on architect of our system’s evolution.

In this role, you will tackle our most substantial engineering challenges: ensuring the reliability, performance, and scalability of our distributed systems while driving the maturation of our technical stack. This is a leadership role for a hands-on technical visionary. 99% reliability and massive scalability.

You will drive key maturation issues regarding our architecture, identifying the critical path for eliminating bottlenecks, reducing complexity, and enabling our engineering teams to ship faster with greater confidence. As a key voice on the Architecture Review Board (ARB), you will shape the technical direction of the entire organization. If you are an expert in high-scale distributed systems and have the scars and success stories to prove it, this is your chance to build a legacy.

Key Responsibilities

System Reliability, Performance, Scalability Solve Substantial System Challenges: You will identify and lead the resolution of the most complex, systemic problems affecting our platform's stability and speed. Architect for Scale: You will design the strategies that allow our system to handle exponential growth, focusing on database scaling, caching architectures, and asynchronous processing throughput. Reliability Engineering: You will define and drive the adoption of patterns that ensure system resilience, including circuit breaking, graceful degradation, and active-active failover strategies.

Stack Architecture Maturation Drive Technical Evolution: You will lead the maturation of our technical stack, ensuring our libraries, frameworks, and infrastructure choices evolve to meet future business needs. Eliminate Structural Bottlenecks: You will look beyond code-level optimization to solve structural issues in our database layer, messaging infrastructure, and deployment pipeline. Technical Governance: As a senior leader on the ARB, you will enforce architectural rigor, preventing the introduction of new technical debt while establishing standards for long-term maintainability.

Strategic Leadership Influence Cross-Organizational Impact: You will influence the technical direction across multiple product areas, reconciling conflicting architectural goals to serve the broader business. Elevate the Platform: You will mentor Staff and Senior engineers, helping them understand distributed consensus, eventual consistency, and the trade-offs of complex distributed systems.

What We’Re Looking For

Elite Distributed Systems Experience: 10+ years of software engineering experience, with a heavy focus on designing, optimizing, and operating high-scale distributed systems. Architectural Evolution: You have a proven track record of evolving complex systems and driving technical maturity in a fast-paced environment. js is required.

As we pivot performance-critical paths toward Go, experience leading similar language transitions or strong Go proficiency is highly desirable. Deep Technical Mastery: Expertise in defining Service Level Objectives (SLOs) and Error Budgets. Deep knowledge of synchronous (Websockets, gRPC, REST) vs.

asynchronous (Kafka/PubSub) communication patterns. Advanced database design patterns (sharding, partitioning, CQRS). Expertise in container orchestration (Kubernetes) at scale.

Visionary Leadership: You can identify critical long-term technical challenges months or years in advance and mobilize the organization to address them.
