Jobs at Sift Stack

Lead design, build, and operate backend agentic systems that analyze large-scale time-series telemetry. Own product from customer discovery through shipping. Implement APIs, distributed job execution on Kubernetes, sandboxed code execution, context/memory management, evaluation suites, and observability while integrating frontier models and scaling agent workloads.

Design and build scalable platforms for high-frequency data ingestion, develop database solutions, and pioneer data architecture while collaborating on engineering standards.

Design and own developer and test infrastructure for production-like environments. Build CI/CD pipelines, deployment automation, data-generation tools, workload simulations, and infrastructure supporting integration, load, performance, and correctness testing. Enable AI coding agents to test and validate code autonomously while improving engineering velocity, reliability, scalability, and cost efficiency. Collaborate with engineering teams to remove development bottlenecks and scale testing systems.

Own end-to-end product design for Sift’s complex, data-rich platform, from user research and problem discovery through prototyping, validation, and launch. Design intuitive workflows for technical users working with telemetry and mission-critical hardware data. Partner with Product and Engineering, contribute to the design system, conduct customer research, participate in critiques, and use AI-assisted tools such as Claude Code and Figma MCP to accelerate prototyping and iteration.

Design and own developer infrastructure for isolated, production-like testing environments. Build CI/CD pipelines, deployment automation, build systems, realistic data and behavior simulation, and infrastructure supporting integration, load, performance, and correctness testing. Enable AI coding agents to test and validate code autonomously while improving engineering velocity, reliability, scalability, and cost efficiency. Partner closely with engineering teams to eliminate development bottlenecks.
