About The Position

This role is for a Senior Full Stack Platform & Infrastructure Engineer who will build production-critical systems for a medical-grade wearable technology platform. The engineer will work across Go backend services, AWS infrastructure, React/TypeScript web surfaces, and mobile-adjacent work, utilizing AI tools extensively. This is a senior individual contributor role at the intersection of platform engineering, infrastructure, backend services, web frontend, and mobile. The company is an early-stage health technology platform with a lean, distributed U.S. engineering team. The role requires an engineer who can unblock work, strengthen global-scale infrastructure, and ship reliable systems in a compliance-aware environment. AI-augmented engineering is a first-class expectation, with extensive use of LLMs, AI coding assistants, and multiple coding agents.

Requirements

• Shipped production work across backend services, cloud infrastructure, and frontend surfaces.
• Strong in Go for backend services, APIs, and systems-oriented engineering.
• Hands-on AWS infrastructure experience across compute, storage, messaging, databases, networking, and observability.
• Fluent with infrastructure-as-code, CI/CD pipelines, deployment automation, and production reliability practices.
• Meaningful React and TypeScript experience and can contribute to product-facing web surfaces.
• Can contribute to iOS and Android codebases when needed, especially with AI-assisted development and strong engineering fundamentals.
• Understand relational and NoSQL databases, messaging/event systems, API design, and high-throughput data movement.
• Can pick up unfamiliar languages, codebases, and systems quickly without needing every tool to be your exact prior stack.
• Comfortable operating as a senior individual contributor in a lean startup environment where scope is broad and ownership is real.
• Can manage multiple AI coding agents or LLM-assisted workflows to accelerate implementation, QA, and code review.
• Communicate technical tradeoffs clearly and keep complex cross-functional work organized without trying to take over areas already owned by teammates.

Nice To Haves

• Experience in health tech, wearables, biometric data, IoT, or device-connected software.
• Background working with HIPAA, SOC 2, GDPR, or other compliance-aware engineering environments.
• Experience with AI/ML platform infrastructure, MCP servers, model-facing backend systems, or AI-assisted developer workflows.
• Developer-facing platform experience, including SDKs, external APIs, enterprise integrations, or partner-facing APIs.
• Experience with high-throughput data upload, ingestion, processing, or analytics systems.
• Prior senior IC experience at a high-scale technology company, or experience returning to hands-on engineering after a management role.

Responsibilities

• Design, ship, and maintain Go-based backend services, REST and gRPC APIs, async workers, and data pipelines.
• Build and attach APIs for platform capabilities, partner algorithms, and client-specific functionality.
• Understand how high-volume wearable data moves through the system, into algorithms, out through outputs, and into product-facing surfaces.
• Improve data models, backend tables, ingestion paths, and service interfaces that support biometric features and platform reliability.
• Own and evolve AWS infrastructure across compute, storage, networking, messaging, databases, load balancing, and observability.
• Use AWS services such as S3, Aurora, ElastiCache, SQS, CloudWatch, load balancers, and autoscaling groups.
• Use infrastructure-as-code practices to improve reliability, cost, scalability, deployment safety, and operational clarity.
• Help the platform scale as the company expands usage across customers, partners, and geographies.
• Build, extend, and maintain CI/CD pipelines across staging and production environments.
• Improve zero-downtime deployment systems, autoscaling configurations, environment management, and release workflows.
• Strengthen testing, monitoring, and rollback patterns so engineers can ship quickly without compromising reliability.
• Contribute to React and TypeScript web dashboard work used by enterprise clients and internal teams.
• Support iOS and Android surfaces as needed, including Swift and Kotlin codebases.
• Use AI-assisted development and strong systems fundamentals to contribute effectively even when a surface is not your primary specialty.
• Contribute to security posture, authentication systems, access control, audit logging, and compliance-aware engineering.
• Work within established HIPAA, SOC 2, and privacy-conscious engineering practices.
• Build simple, testable, maintainable systems that can be trusted in a health technology environment.
• Coordinate across backend, frontend, mobile, infrastructure, and product workstreams.
• Translate partner algorithm requirements into platform implementation paths across data flows, APIs, web, Android, and iOS.
• Respect existing ownership across the engineering team while helping unblock work and move complex multi-layer projects forward.

Benefits

• Earn a $175,000 base salary, with final compensation dependent on experience, skill level, and assessment performance.
• Fully remote, distributed U.S. engineering team with broad ownership and meaningful autonomy.
