Ownership of product area

Descripción de la vacante

We Love AI Jobs is seeking a Senior Backend Software Engineer to own product work on Sift Agents, helping hardware engineers investigate anomalies and analyze telemetry. You will build dependable agent systems and support services, from tool interfaces and evaluations to distributed execution on Kubernetes.

This product engineering role gives you real ownership: talk to customers, decide what to build, and ship it from MVP through iterations.

Formación

• 8+ years of professional software engineering experience.
• Own a product area by talking to customers, deciding what to build and shipping it.
• Built APIs (REST, gRPC) and complex backend services with Go, Python, or Rust.
• Working knowledge of distributed systems fundamentals.
• Curious about new AI products and capable of evaluating agents and models.

Responsabilidades

• Design and operate agent systems that analyze large-scale telemetry and hardware context.
• Build agent tools, execution environments, context management, guardrails, and evaluations.
• Develop distributed services and Kubernetes workloads for resilient agent execution.
• Design job-based execution systems that scale and manage agent workloads on Kubernetes.
• Develop and maintain MCP server and APIs powering agentic capabilities.
• Create evaluation suites to measure impact, latency, cost, and failure modes.

The 719 open senior engineering jobs that publish US pay start at $164K on average, so this job starts about 10% higher.Similar open jobs: We Love AI Jobs lists 1,635 open senior engineering jobs at 344 companies.Remote work: This job is hybrid. 271 of the 1,635 senior engineering jobs (17%) are remote.AI in this role: High. AI is the core of the work: building, training or deploying AI systems. The role builds and operates Sift Agents, which investigate anomalies and answer questions about telemetry. Responsibilities include agent design, evaluation, model integration, and the tools and infrastructure that make agents dependable.## Full descriptionAbout SiftSift is the data infrastructure platform for hardware engineering teams. We turn high-frequency telemetry into engineering insights for mission-critical machines: rockets, satellites, autonomous vehicles, energy systems, and defense platforms. Founded by former SpaceX engineers, we are building the review and analysis layer for the AI era of physical systems.About The RoleHardware programs generate far more telemetry than any team can review by hand. Sift Agents is our answer: AI agents that work alongside hardware engineers, investigating anomalies, reviewing test and flight data, and answering in minutes questions that used to take a day of scripting.This role comes with real product ownership and autonomy. You will talk directly to customers to understand how they review their machines, decide what to build, and own it from first MVP through every iteration after it ships. The surface area is wide: one day you might be designing the tool interface an agent uses to query billions of telemetry points, the next you might be writing the Kubernetes scaling logic that orchestrates agent workloads. We’re heavy users of frontier agentic products ourselves and have strong opinions about what makes them great. Sift Agents is where we put those opinions to work.This is a product engineering role, not a research role. Most of the work is the hard part of making agents dependable: tool design, context management, code execution environments, evaluation, and observability.In This Role, You'll:• Talk directly to customers and partner with product to turn real review workflows into agent capabilities: generating dashboards, writing analysis scripts, and surfacing insights buried in their telemetry• Design, ship, and operate agentic systems that reason over large-scale time-series data and hardware domain context• Build everything around the model that makes agents dependable: tool interfaces, sandboxed execution for agent-generated code, context and memory management, custom compaction algorithms, opinionated skills, and guardrails• Build the distributed systems that let long-running agent work stream in real time, survive disconnects, and resume across restarts• Design job-based execution systems that schedule, scale, and tear down agent workloads on Kubernetes, both in the cloud and on-prem• Develop and maintain Sift’s MCP server, the tool surface that lets both our agents and our customers’ AI tools query telemetry directly• Design and implement the APIs that power our agentic capabilities• Build evaluation suites that measure whether agents actually help engineers, and instrument quality, latency, cost, and failure modes in production• Integrate and assess frontier models across providersThe Skillset You'll Bring:• Have 8+ years of professional software engineering experience• Get excited about owning a product area: talking to customers, deciding what to build, and shipping it• Have built APIs (REST, gRPC, etc.) and complex backend services with technologies like Go, Python, Rust, or similar• Have a working knowledge of distributed systems fundamentals• Are curious about new AI products: you try new agents, models, and features as they ship, and have opinions about what makes them goodIf this role excites you, apply even if you don’t check every box.Bonus Points:• Shipped products to users at scale: large data volumes, significant active user counts, or deep technical complexity• Shipped LLM-powered features• Built agentic systems: multi-step tool use, planning loops, context management, and evals• Designed tool ecosystems for agents, including MCP• Worked with sandboxed or isolated execution of generated code
