What you’ll need to succeed

• Proven experience as a Senior Software Engineer, delivering complex backend or platform solutions in production environments
• Deep knowledge of the Go Programming Language ecosystem, including concurrency, performance tuning, and service design
• 5+ years of professional software engineering experience, with 2+ years of hands‑on production experience in Go and/or other modern backend languages
• Practical experience building or integrating AI‑powered applications, including APIs based on OpenAI, Anthropic, or similar LLM platforms
• Familiarity with concepts such as prompt engineering, retrieval‑augmented generation (RAG), function/tool calling, conversation orchestration, and model evaluation
• Strong understanding of software architecture, design patterns, and best practices, with a track record of applying them to scalable systems
• Experience designing, building, and maintaining distributed systems and microservices architectures
• Experience developing systems that require high availability, observability, security, and strong operational excellence
• Experience with MongoDB or other NoSQL databases
• Hands‑on experience with Amazon Web Services and cloud‑native infrastructure patterns
• Working knowledge of containers and developer tooling, including Docker, Git, and CI/CD pipelines
• Strong communication skills, a collaborative mindset, and experience working with cross‑functional teams
• Good level of English (B2 or higher)

It would be a plus

• Experience working directly with users, product owners, and stakeholders to gather requirements and translate business needs into technical solutions
• Experience with infrastructure as code and deployment automation, including Amazon Web Services CDK, Terraform, or similar tooling
• Working knowledge of frontend development using JavaScript, HTML, CSS, and React
• Proficiency in Python for automation, scripting, data processing, AI integrations, or rapid prototyping
• Experience using modern AI‑assisted engineering tools such as Cursor, Anthropic Claude Code, GitHub Copilot, or similar developer productivity platforms
• Familiarity with CI/CD pipelines, developer workflows, and engineering practices that accelerate high‑quality software delivery
