Responsibilities

• Build and own components of the rule evaluation engine — the decision logic at the heart of Data Products — including authoring rules, evaluating them at scale, and exposing results to downstream systems
• Develop backend services in Python (FastAPI) that handle high-throughput, low-latency evaluation worklo
• Work with event-driven infrastructure (Kafka or equivalent) to integrate the engine with upstream data sources and downstream consumers
• Design and evolve data models that support auditability, versioning, and reproducibility of rule outcomes
• Build React interfaces that let merchants and internal users configure rules, inspect evaluations, and trust the system
• Contribute across the full spectrum of the Data Products team’s work—business rules automation, ML-based APIs, customer-facing analytics, and intelligent recommendation systems
• Partner with Data Science, Analytics Engineering, and Product to translate analytical signals into productionized decisions
• Instrument what you ship: write meaningful tests, add metrics and tracing, and use production data to validate that changes landed as intended
• Participate in team oncall and incident response for the services you own
• Contribute to API design, service decomposition, and cross-team technical reviews as you grow into broader ownership
• Help onboard new team members and share knowledge through code reviews, design docs, and pairing
• Use AI coding tools (Claude, Cursor) effectively in your daily workflow and contribute to evolving team norms around them

Skills

• 6+ years of professional software engineering experience, with at least 2 years shipping production full-stack features
• Strong Python backend skills
• Hands-on experience with event-driven systems (Kafka or equivalent) in production
• Solid PostgreSQL skills, including schema design, indexing, and query performance
• Production-level React experience, including state management and integration with backend APIs
• Comfortable shipping behind feature flags, instrumenting code for observability, and iterating based on production signal
• Practiced at writing tests (unit and integration) and treating reliability as part of the work, not a follow-up task
• Strong written communication; able to write a clear design doc, scope a feature, and unblock yourself across teams
• Curious about the domain — willing to learn the shipping and logistics context deeply enough to make good product calls
• FastAPI (or comparable async Python framework) experience preferred
• Prior experience designing or building rule engines, evaluation logic, or decision systems is a strong plus
• Domain experience in shipping, logistics, carrier APIs, or rate selection
• Experience with feature flags and progressive rollout systems
