Senior Web Services Engineer

What you will do:

• Design and implement scalable database schemas and API interfaces to support large-scale user-generated content, with a focus on security, performance, and developer experience for enterprise-grade applications.
• Architect clean, performant RESTful APIs, GraphQL solutions, and AI-powered features that bridge legacy systems with modern platforms including Stripe, Shopify, Salesforce, and OpenAI.
• Build and integrate Customer Data Platforms (CDPs) and AI/ML capabilities, including semantic search, RAG, vector embeddings, and prompt engineering, to enhance application intelligence.
• Guide end-to-end project execution from scoping client requirements to hands-on development using Python, Node.js, Go, and occasionally PHP, including troubleshooting third-party integrations, resolving performance bottlenecks, and writing automated tests.
• Collaborate with cross-functional teams and clients to translate complex business requirements into actionable technical solutions, working remotely with a globally distributed team across multiple time zones.

About you:

• You have 5+ years of backend API development experience, ideally using Python/Django, Node.js/NestJS, or Golang/Gin, and have built APIs for at least 3 enterprise apps involving complex third-party integrations in fast-paced environments.
• You thrive in ambiguity and bring structure to unstructured problems, clearly communicating technical trade-offs to non-technical stakeholders, even when specs are incomplete or priorities shift.
• You have a strong understanding of agile methodologies and believe that effective collaboration drives the best results.
• You are proficient in system design and SQL data modeling for high-traffic applications (10k+ daily users).
• You bring hands-on experience implementing production-ready LLM features, including semantic search, vector databases, RAG, and prompt engineering.
• You embrace continuous learning and see this role as a chance to solve technical challenges, blending legacy systems with modern web services.
