Fit analysis

The candidate possesses strong senior-level full-stack and infrastructure experience, but the resume lacks direct evidence of proficiency in Golang, Python, Kubernetes, or AI agent development, which are core requirements for this specific role.

Where you fit

  • Seniority: Over 7 years of professional software development experience (2018 - present), meeting the general senior developer requirement.
  • Full-Stack Development: Proficient in architecting and deploying complex systems using Next.js, React, Node.js, and Rust, demonstrating breadth across modern web stacks.
  • Infrastructure & High Availability: Engineered and maintained operational protocols for a 1,800+ asset fleet and designed scalable power/network infrastructure, proving capability in mission-critical environments.
  • Data Management: Expertise with complex data integration using GraphQL (Hasura), PostgreSQL, and building real-time telemetry pipelines (Rust/JavaScript).
  • E-commerce Architecture: Proven ability to architect high-performance headless B2B storefronts using Next.js and Shopify, managing complex product configurators.

Where you may struggle

  • Golang/Python Experience: The job requires 3+ years of Golang and/or Python experience; the resume focuses heavily on Rust, JavaScript, and Node.js, making this a significant technical risk.
  • Kubernetes Experience: Requires 2+ years with Kubernetes (K8s); there is no mention of container orchestration or K8s in the candidate's experience.
  • AI Agent Development: The role requires 2+ years of AI agent development experience; the resume focuses on IoT telemetry and e-commerce, showing no domain knowledge in LLMs or AI agents.
