OUR CLIENT This is a design-led lifestyle and e-commerce marketplace operating at the intersection of technology, art, and consumer retail. The organization connects a global community of independent artists with customers seeking distinctive, premium products across stationery, art, and home décor. JOB SUMMARY We are seeking a Senior Software Engineer to drive the design, delivery, and evolution of core components within our Orders Platform, including cart, payments, shipping, and order management. This role spans end-to-end ownership from technical design and implementation to deployment, monitoring, and production stability. You will build resilient, scalable e-commerce microservices, integrate complex third-party systems (payment gateways, shipping providers, compliance services), and ensure distributed data consistency across systems. The role includes contributing to the migration from a monolithic architecture to modern microservices, implementing decomposition strategies, and supporting frontend modernization efforts. You will design extensible RESTful APIs, optimize performance through caching and database improvements, manage infrastructure enhancements (Redis, CI/CD, Kubernetes), and proactively resolve production issues. In addition, you will mentor engineers, author technical design documents, and collaborate cross-functionally to deliver stable, high-impact features at scale. RESPONSIBILITIES - Lead component-level projects (cart, payments, shipping, orders) across the Orders Platform, from design and implementation to deployment and monitoring. - Design and build resilient, scalable e-commerce microservices (cart, payment gateways like CyberSource/Apple Pay/PayPal, shipping/fulfillment like FedEx/ShipEngine), ensuring distributed data consistency. - Drive the migration from a monolith to modern microservices using decomposition patterns (e.g., Strangler Fig) and modernize the frontend (React, CJS-to-ESM, Webpack-to-Vite). - Design and implement RESTful API services for various consumers, focusing on extensibility, caching (Redis/Valkey), and third-party rate limiting. - Integrate third-party payment and compliance systems (e.g., CyberSource MLE), adhering to security best practices and deadlines. - Create and maintain operational dashboards, monitoring, and alerting using Grafana, CloudWatch, and Sentry for system health and quick production issue identification. - Write extensible, well-tested code with high unit test coverage, delivering stable features consistently. - Manage infrastructure tasks including Redis upgrades, database optimization (read replicas, slow query remediation), CI/CD improvements, and Helm/Kubernetes configuration. - Investigate and resolve production issues quickly, identifying root causes, predicting ramifications, and implementing preventative fixes. - Collaborate with Product, QA, and cross-functional teams to meet requirements, proactively communicate status/blockers, and plan 1-2 weeks ahead. - Mentor engineers and interns, sharing system knowledge, best practices, and architectural decisions. - Author detailed technical design documents for complex projects, covering context, proposed approaches, performance, phased plans, and acceptance criteria. QUALIFICATIONS AND JOB REQUIREMENTS - 8+ years of professional experience as a software engineer, with demonstrated ability to own and deliver complex, multi-week projects independently. - A B.S. in Computer Science or equivalent experience. - Strong, hands-on programming skills in Python (primary) with working knowledge of at least one additional language (JavaScript/TypeScript, PHP, or similar). - Experience building and maintaining microservices and event-driven systems (Kafka, message queues, async consumers) in a production environment. - Practical experience with monolith-to-microservice migration, decomposing legacy systems, managing dual-write patterns, and incrementally routing traffic to new services. - Working knowledge of frontend technologies including React, TypeScript, and modern build tooling (Vite, Vitest); comfort working across the full stack when needed. - Experience with payment gateway integrations (CyberSource, PayPal, Apple Pay) including tokenization, encryption, and compliance requirements. - Familiarity with shipping and fulfillment systems, carrier API integrations (FedEx, UPS, USPS), tracking event processing, and delivery estimation logic is a plus. - Hands-on experience with cloud infrastructure: AWS (ElastiCache/Redis, CloudWatch, SNS, S3), Docker, Helm, Kubernetes, and CI/CD pipelines (GitLab CI preferred). - Strong understanding of database design and optimization, MySQL query performance, read replica strategies, caching layers (Redis/Memcached), and data consistency patterns. - Experience with observability and monitoring tools: Grafana, Prometheus, Sentry, CloudWatch, including building dashboards and configuring alerts proactively. - Effective verbal and written communication skills; ability to write clear technical design documents and articulate decisions to engineers and stakeholders. - Demonstrated ownership mindset: follows through on tasks end-to-end, accepts responsibility for outcomes, and delights the end user. - The desire to ship is greater than the desire to polish. - Demonstrated willingness to use AI tools to assist in day to day work.
