Acting as the Technical Lead and Primary Architect, you will be a hands-on leader responsible for the team’s overall delivery. You will lead a small squad by decomposing complex product requirements into actionable tasks, providing deep technical mentorship, and guiding the architectural direction while remaining deeply embedded in the codebase.\nKey Responsibilities:\nTechnical Execution: Lead technical delivery by translating high-level product roadmaps into actionable development cycles. Partner with Product Owners to define scope and ensure high-quality output through rigorous code reviews and technical mentorship \nTransactional Microservices: Architect and develop high-concurrency backend services in Python (FastAPI/Django) to handle core business logic, including shopping carts, order processing, and complex transactional workflows \nTool Engineering for Agents : Design and implement \"Agent-Ready\" APIs using Pydantic for strict type enforcement and OpenAPI/MCP for autonomous service discovery, allowing agents to execute business actions (like placing an order) with 100% reliability. \nIntegration Frameworks: Build and maintain secure, scalable integration layers (OAuth2, Webhooks) to connect the SmartEquip platform with diverse customer ERP and procurement systems \nObservation-Friendly APIs: Implement advanced error-handling and \"hinting\" within API responses to allow autonomous agents to self-diagnose and correct invalid requests during complex multi-step tasks\nAI-Native SDLC: Actively utilize autonomous coding agents to plan, generate, and test backend code, maintaining high velocity while ensuring code quality through agent-assisted peer reviews.\nSecurity & Auth: Own the implementation of secure authorization protocols (JWT,OpenID Connect) to ensure that both humans and AI agents operate within strict permission boundaries\nPerformance Optimization: Monitor and optimize API latency and database query performance (PostgreSQL/MS SQL) to support real-time interaction for both web/mobile apps and high-frequency agent calls.\nSkills and Experience:\n10+ years of Software Engineering experience, with a proven history of leading technical squads, architecting, and building complex transactional backend systems.\nExpert mastery of Python (FastAPI, Django) and proficiency in modern Front-end frameworks (Angular/Typescript).\nDeep mastery of RESTful API design, specialized in Tool-Calling patterns and structured data exchange for LLMs.\nStrong SQL skills (PostgreSQL/MS SQL) and production experience with OAuth2/JWT for secure service-to-service communication.\nExperienced in working with cloud platforms (GCP, AWS) and deploying containerized services that are secure and scalable.\nDemonstrated proficiency in using coding agents to accelerate the SDLC and plan and code complex engineering tasks.","description_format":"text","description_chars":3029,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Auctions","Marketplaces"],"lifecycle":[{"event":"open","at":"2026-10-18T08:37:35Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long
