Senior Backend Engineer, Integrations

Role Overview

• Design, develop, and operate backend services that power Arbiter's core platform, with an emphasis on reliability, modularity, and clean system boundaries.
• 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.
• 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.
• 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.
• Build and maintain ETL/ELT pipelines, manage schema evolution, and ensure data quality and integrity across systems with varying formats, standards, and reliability.
• Implement and uphold best practices for CI/CD, testing, observability, and deployment of backend systems in production cloud environments.
• Partner closely with AI engineers, product managers, implementation teams, and customer stakeholders to translate ambiguous, high-impact problems into scalable technical solutions.
• Mentor engineers, contribute to internal documentation and standards, influence technical direction, and raise the overall engineering bar.
• Take end-to-end ownership of critical systems, including participating in on-call rotations and leading incident resolution when production issues arise.

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.
