Staff Full-Stack Engineer: Build Scalable Python & React

Jobtailor; Palo Alto (CA); On-site; USD 180,000 - 230,000; Full time

Job summary

Jobtailor is hiring for a senior software engineer to design and operate Python microservices and gRPC APIs that expose high-performance C++ engines. You will build front-end features with React/TypeScript, implement end-to-end logic, and help scale distributed systems with observability and autoscaling.

The role involves debugging across frontend, Python, and native components, plus contributing to CI/CD pipelines, testing, and on-call incident response.

Qualifications

• 5+ years professional software engineering experience building backend or full-stack systems.
• Strong experience with Python service development (sync/async) and building/consuming gRPC/protobuf APIs.
• Practical PostgreSQL experience including schema design, safe migrations, query tuning, indexing, and production query optimization.
• Practical experience with React or equivalent modern frontend framework, TypeScript/JavaScript, HTML/CSS, and shipping UI changes to production.
• Experience distributing compute with MPI, task queues, or job schedulers; knowledge of Kubernetes, Slurm, or HPC schedulers preferred.
• Experience with observability tooling (Prometheus, OpenTelemetry) and secure frontend/backend interactions preferred.

Responsibilities

• Design, implement, and operate Python-based microservices and gRPC APIs exposing native C++ engines and simulation pipelines.
• Implement UI changes for customer-facing React apps using TypeScript/JavaScript.
• Handle end-to-end logic including request validation, job orchestration, retries, and transactional correctness.
• Help design distributed systems with partitioning, backpressure, observability, and autoscaling.
• Debug and profile frontend, Python runtime, and native C++ performance.
• Build CI/CD pipelines and automated tests across backend, frontend, and native components.
• Participate in on-call rotations, incident response, and post-mortems; maintain runbooks.
• Collaborate with product, QA, infra, and customer success to deliver secure, documented features.
• Mentor teammates and contribute to code reviews and engineering best practices.
