Key Responsibilities:

• Design and build scalable backend services and APIs using Golang, including REST and GraphQL APIs, queries, mutations, and resolvers.
• Implement efficient data models, schemas, and queries using MongoDB, with attention to performance, scalability, and maintainability.
• Build dynamic, server-rendered user interfaces using HTMX and Templ, leveraging partial-page updates for responsive experiences with minimal JavaScript.
• Collaborate with designers and engineering teams to deliver responsive and accessible interfaces using Tailwind CSS and Alpine.js.
• Apply unit and integration testing, code reviews, debugging, CI/CD, and engineering best practices throughout the development lifecycle.
• Deploy and support applications in cloud environments, troubleshooting issues across development and production.
• Apply AI-assisted development practices across coding, testing, code review, documentation, troubleshooting, and engineering productivity.

Qualifications:

• 6+ years of software development experience, with strong hands-on expertise in Golang.
• Hands-on experience designing and developing REST and GraphQL APIs, including queries, resolvers, and schema design.
• Proficiency with MongoDB, including schema design, querying, and performance optimization.

• Experience with CI/CD pipelines, Docker, automated testing, code reviews, debugging, and modern software engineering practices.
• Knowledge of AI-Assisted Development Lifecycle (AIDLC) practices, including the use of AI-powered coding assistants, automated testing, code review, documentation generation, and productivity tools.
• Understanding of Large Language Models (LLMs), prompt engineering, Retrieval-Augmented Generation (RAG), AI governance, and responsible AI principles.
• Experience integrating AI capabilities into enterprise applications through APIs and cloud-native AI services.
• Ability to evaluate and adopt emerging AI technologies to accelerate software delivery and improve quality.
• Strong problem-solving, communication, and collaboration skills, with the ability to work effectively within Agile, cross-functional product teams.

Set Yourself Apart With (Nice to Have)

• Hands-on experience with AI-assisted software development tools and workflows, such as GitHub Copilot, Claude, ChatGPT, or comparable AI- enabled engineering tools.
• Deeper experience applying the AI Development Lifecycle (AIDLC), including responsible AI, prompt engineering, model integration, testing, monitoring, and governance.
• Experience building or integrating AI-powered applications using LLMs, Retrieval-Augmented Generation (RAG), and agentic AI patterns.
• Experience with distributed systems and event-driven architectures.
• Hands-on experience optimizing Go applications for latency, throughput, scalability, and resilience.
• Familiarity with modern DevOps and observability practices in production cloud environment
