Software Engineer - Systems

About the Role: Build and operate the core platform behind Boson’s model APIs and agentic products. You’ll own the infrastructure that every Boson agent runs on - API serving, state management, data pipelines, context retrieval, and execution runtime - and make it fast, reliable, and easy for product teams to build on., * Own and evolve the core platform infrastructure: API serving layer, state management, policy enforcement engine, and execution runtime for agentic workflows.

• Design and operate high-throughput, low-latency distributed services that back our model API products - including request routing, load management, rate limiting, and multi-tenant isolation.
• Build and maintain downstream data pipelines (ETL/ELT) for API logs, usage analytics, and billing - ensuring data correctness, freshness, and queryability at scale.
• Develop production-grade internal SDKs and libraries with clean APIs, strong type safety, and clear contracts that product teams can build on confidently.
• Architect context and memory systems for conversational workloads - low-latency retrieval, caching, and integration with vector stores and retrieval pipelines.
• Instrument end-to-end observability: define SLIs/SLOs, build structured logging and tracing, and drive reliability improvements across the platform.
• Collaborate closely with ML and product teams to integrate model serving, voice runtime, and tooling infrastructure under tight latency and quality constraints.

• 3+ years building and operating backend systems at scale - you’ve owned services that other teams depend on in production.
• Strong distributed systems fundamentals: concurrency, fault tolerance, consistency tradeoffs, capacity planning.
• Hands-on experience with data pipeline infrastructure (Kafka/Kinesis, Spark/Flink, Airflow, or similar) for log processing, analytics, or ETL workloads.
• Track record of designing APIs and frameworks adopted by other engineering teams - you care about developer experience and long-term maintainability.
• Proficiency in at least one systems language (Go, Rust, Java, C++) or Python in a performance-sensitive context.
• Comfortable working across the stack: cloud infrastructure (AWS/GCP), containerized deployments (K8s), CI/CD, and production oncall., * Experience with LLM serving, agentic orchestration patterns (ReAct, planner-executor), or RAG pipelines.
• Familiarity with emerging agent integration protocols (MCP, A2A) or orchestration frameworks (LangChain, LlamaIndex).
• Background in real-time media systems (audio/video streaming, low-latency signaling).
• Experience building high-stakes platform services (payments, identity, core data) where correctness and auditability are non-negotiable.
