Senior Backend Engineer (Python/FastAPI)

Salary: $? - ? per yearRequirements:Several years of software engineering experience (3 years or more)Strong expertise in systems programming, infrastructure, or backend development using languages like Python, C/C++, Rust, and Go.Experience building and deploying scalable, production-grade software using modern languages and tools.Deep understanding of software architecture, design, development, debugging, and code quality/review assessment.Excellent oral and written communication skills for clear, structured evaluation rationales.Responsibilities:Ideal BackgroundThis role is ideal for engineers who have built production systems at companies like Google, Microsoft, Apple, Amazon, Meta, or similar high-scale engineering organizations. We especially welcome graduates from programs with strong CS foundations such as University of Washington, University of Illinois Urbana-Champaign, UT Austin, University of Michigan, Purdue, and comparable institutions — though exceptional experience and skill always take precedence over pedigree.Project Overview:As a Software Engineering evaluator, you will create cutting-edge datasets for training, benchmarking, and advancing large language models, collaborating closely with researchers. This includes curating code examples, providing precise solutions, and making corrections in Python, C/C++, Rust, Go, Java, and JavaScript (including ReactJS) — with particular emphasis on systems-level code, performance-critical applications, and infrastructure. You will evaluate and refine AI-generated code for efficiency, scalability, and reliability, and work with cross-functional teams to enhance enterprise-level AI-driven coding solutions.What Does a Typical Day Look Like?Work on AI model training initiatives by curating code examples, building solutions, and correcting code in Python, C/C++, Rust, Go, Java, and JavaScript (including ReactJS).Evaluate and refine AI-generated code with an emphasis on systems-level correctness, performance, and reliability.Collaborate with cross-functional teams to enhance AI-driven coding solutions against industry performance benchmarks.Build agents that can verify the quality of systems-level and infrastructure code and identify error patterns.Hypothesize on steps in the software engineering cycle (prototyping, architecture design, API design, production implementation, launch, experiments, monitoring, operational maintenance) and evaluate model capabilities on them.Design verification mechanisms that can automatically verify a solution to a software engineering task.Technologies:AIAPIBackendJavaJavaScriptPythonRustFastAPIMore:Engagement Details:Commitment: flexible engagement, minimum 10 hrs/week, up to 40 hrs/weekType: Contractor (no medical/paid leave)Duration: 1 month (potential extensions based on performance and fit)Location: Candidates must be based in the United StatesEvaluation Process:The application process takes 15–30 minutes.Completion of an AI video interview is required.last updated 20 week of 2026
