Requirements
• 5+ years of hands-on experience building and operating production backend systems in high-availability environments. • Computer Science or Engineering degree, or equivalent practical experience. • Experience building and maintaining large-scale Python codebases with strong opinions on structure, quality, and tradeoffs. • Deep understanding of API design patterns, versioning, backward compatibility, and managing breaking changes across consumers. • Experience building reusable abstraction layers or connector frameworks that allow a single integration pattern to serve multiple customers or vendors. • Proven experience designing systems that connect to third-party services, including handling authentication, rate limiting, retry logic, and failure modes gracefully. • Strong understanding of concurrency, scalability, reliability, and distributed systems patterns. • Hands-on experience with data pipeline architectures: batch and streaming, schema management, and data quality enforcement. • Experience with cloud infrastructure (AWS, GCP, or Azure) and production deployments. • Strong communication skills and ability to work effectively across functions. • Proficiency with AI-assisted development tools (e.g., Cursor, Claude Code, GitHub Copilot). • Track record of delivering complex systems end-to-end with minimal oversight. • Experience with healthcare data exchange standards (HL7, FHIR, EDI) or similarly complex domain-specific protocols in other industries (fintech, telecom, logistics) is a plus. • Familiarity with database performance tuning, query optimization, and managing large-scale relational databases (PostgreSQL, CloudSQL). • Startup or early-stage experience operating in fast-moving, high-ambiguity environments. • This role can be remote or on-site, based in our New York City or Boca Raton offices, in a fast-paced, collaborative environment where great ideas move quickly from whiteboard to production.
Responsibilities
• As a Senior Backend Engineer, you will design, build, and operate the platform systems that power Arbiter's connections to the outside world and ensure reliable, performant data exchange across a complex ecosystem. You will own critical parts of our backend infrastructure, from API design and service orchestration to data pipelines and third-party system connectivity, working closely with product, engineering, and customer teams to ship production-grade systems with real customer dependency. • Platform Architecture & Backend Systems: Design, develop, and operate backend services that power Arbiter's core platform, with an emphasis on reliability, modularity, and clean system boundaries. • External System Connectivity: Build and maintain robust connections to third-party systems (e.g. cloud APIs, AI services, data exchange services, EHRs, telephony platforms). Own the abstractions that make these integrations reusable and adaptable across customers with minimal rework. • API Design & Data Exchange: Design and operate high-scale APIs (REST, gRPC, webhooks) and manage complex data flows including real-time streaming, batch processing, file-based exchange (e.g. SFTP, HL7, EDI), and event-driven pipelines. • Performance & Reliability: Ensure high throughput, low latency, and fault tolerance across backend services through strong system design, monitoring, alerting, and operational best practices. Handle vendor failures, retries, idempotency, and graceful degradation. • Data Engineering & Pipeline Ownership: Build and maintain ETL/ELT pipelines, manage schema evolution, and ensure data quality and integrity across systems with varying formats, standards, and reliability. • Infrastructure & Deployment Excellence: Implement and uphold best practices for CI/CD, testing, observability, and deployment of backend systems in production cloud environments. • Cross-Functional Execution: Partner closely with AI engineers, product managers, implementation teams, and customer stakeholders to translate ambiguous, high-impact problems into scalable technical solutions. • Technical Leadership & Mentorship: Mentor engineers, contribute to internal documentation and standards, influence technical direction, and raise the overall engineering bar. • Ownership & On-Call: Take end-to-end ownership of critical systems, including participating in on-call rotations and leading incident resolution when production issues arise.
