Join us in the heart of New York City and contribute to our endeavor to ensure that AI is guided by human values, the most pivotal challenge (and opportunity) of the 21st century.\n\nAbout Us\nHume AI is a Series B startup dedicated to building artificial intelligence that is directly optimized for human well-being. As the first company to release speech language models, we’re focused on expanding our research to encompass audio understanding models and evaluation platforms for enterprises.\nOur goal is to enable a future in which technology draws on an understanding of human emotional expression to better serve human goals. As part of our mission, we also conduct groundbreaking scientific research, publish in leading scientific journals like Nature, and support a non-profit, The Hume Initiative, that has released the first concrete ethical guidelines for empathic AI (www.thehumeinitiative.org). You can learn more about us on our website (https://hume.ai/) and read about us in WIRED, Forbes, and Venturebeat.\nAbout the Role\nAs a Senior Software Engineer on the Backend Engineering team, you will help build the backend microservices that power Hume’s APIs and control planes. You will work closely with data plane engineers, UI engineers, research scientists, machine learning engineers, product managers, and infrastructure engineers to bring new product features and inference capabilities into production.\nThis is a systems-oriented backend role focused on reliability, performance, scalability, and efficient resource utilization. You will operate with a high degree of autonomy, make sound architectural decisions, and own systems throughout their lifecycle-from initial design and implementation through deployment, observability, and production support.\nWhat You’ll Do\nDesign, build, and maintain the backend microservices that deliver Hume’s voice AI capabilities to users.\n\nDesign and develop public-facing and internal APIs that are secure, reliable, performant, and highly available.\n\nDiagnose complex production issues across application, operating system, container, and networking layers.\n\nBuild capabilities such as real-time audio streaming and integrations with model inference systems.\n\nDesign and develop control plane APIs that coordinate inference workloads across data planes.\n\nProfile and optimize latency, throughput, memory usage, and resource utilization.\n\nImprove the observability, resilience, testability, and operational safety of the platform.\n\nMake architectural and implementation tradeoffs across reliability, performance, complexity, and development velocity.\n\nCollaborate with research and product teams to turn emerging model capabilities into reliable production systems.\n\nWrite clear technical documentation for the systems and features you build.\n\nWhat You’ll Bring\nSignificant professional experience building server-side, distributed, or systems software.\n\nA deep understanding of networking protocols and concepts, including TCP, TLS, HTTP, and WebSocket.\n\nProfessional experience with at least one systems-oriented programming language, such as Rust, Go, C, or C++.\n\nStrong Linux fundamentals and hands-on experience troubleshooting and profiling production systems.\n\nExperience with one or more relevant systems areas, such as distributed systems, networking, concurrency, resource management, filesystems, or computer architecture.\n\nExperience designing, operating, and evolving production APIs and backend services.\n\nExperience with testing frameworks and CI/CD workflows.\n\nExperience with databases such as PostgreSQL, DynamoDB, or Google Cloud Datastore.\n\nA strong sense of ownership and the ability to make pragmatic engineering and architectural decisions independently.\n\nExcellent written and verbal communication skills. Engineers at Hume document the systems and products they build.\n\nThe ability to use AI-assisted coding tools effectively to accelerate delivery while retaining ownership of the result-including the ability to explain, validate, debug, and modify the resulting code independently when necessary.\n\nBonus Points\nDemonstrated experience designing or building high-concurrency, high-throughput, or latency-sensitive systems.\n\nExperience designing or operating control plane/data plane architectures.\n\nExperience with Kubernetes.\n\nExperience with observability and distributed tracing tools such as Datadog, Prometheus, or OpenTelemetry.\n\nExperience with L4/L7 proxies such as NGINX, HAProxy, or Envoy.\n\nExperience designing REST or gRPC APIs and OpenAPI specs.\n\nExperience building container images and maintaining production CI/CD pipelines.","description_format":"text","description_chars":4767,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Speech & Audio AI","AI Training Data & Annotation","AI Evaluation & Observability"],"lifecycle":[{"event":"open","at":"2026-09-25T14:29:25Z"}],"liveness":{"score":68,"band":"ok","label":"Likely open","p_open":1,"p_active":0.753,"p_room":0.9,"age_days":23,"expected_fill_days":42,"reasons":["conf:1","win:mid"],"computed_at":"2026-09-26T05:45:00Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/hume-senior-software-engineer-microservices","json_url":"https://alion.io/job/hume-senior-software-engineer-microservices.json","meta":{"generated_at":"2026-09-27T04:51:03Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":4237,"day_limit":5000,"remaining_today":763,"minute_limit":60,"resets_at":"2026-09-28T00:00:00Z"}}}
