Engineering Tech Lead

Our requirements

• Strong proficiency in Java/Spring Boot (REST APIs, event-driven services, security, performance optimization).
• Solid React development skills and API integration.
• Experience with relational and in-memory databases (PostgreSQL, Redis).
• Knowledge of messaging and streaming platforms (Kafka or equivalent).
• Hands-on experience engineering prompts for production LLM applications (not just prototypes).
• Familiarity with prompt evaluation frameworks (PromptFlow, LangSmith, Braintrust, or custom pipelines).
• Understanding of tokenization, context limits, temperature tuning, and model-specific behaviors.
• Experience structuring prompts for tool/function calling, structured JSON output, and multi-turn conversations.
• Kubernetes (deployments, services, ingress, Helm, Kustomize, HPA, RBAC).
• CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, or equivalent).
• Infrastructure as Code (Terraform).
• Cloud platforms (AWS, GCP, or Azure).

Your responsibilities

• Design, build, and ship production-quality services within business controls.
• Build and optimize DevOps pipelines, enhancing CI/CD processing, testing, and observability.
• Collaborate with product and domain teams to translate business requirements into technical solutions.
• Design, iterate, and optimize prompts for LLM use cases: instruction following, structured output generation, classification, summarization, code generation, and reasoning.
• Build and manage prompt libraries and versioning strategies, treating prompts as first-class engineering artifacts.
• Architect and implement autonomous agentic systems, including multi-agent pipelines, tool-use workflows, and memory-augmented reasoning.
• Implement LLM observability (logging, tracing, evaluation pipelines, and guardrails) to ensure quality and reliability.
• Advise on responsible AI deployment, including output validation, human-in-the-loop design, and risk mitigation.
