Deep, hands-on experience designing and debugging multi-threaded concurrent applications, lock-free data structures, memory management, thread pools, and race condition diagnostics. * Hands-on experience with AI coding agents (e.g. Gemini CLI, Claude Code, Codex, etc) in real production workflows: multi-step agent tasks, agent-authored PRs, agent-driven test generation. * Deep experience with Google Cloud Platform (GCP) services (GKE, Pub/Sub, BigQuery, Cloud Run, Dataflow) and real-time messaging frameworks (Kafka, MQ, Flink). * Strong proficiency in SQL, Postgres DB, and Python (for scripting, automated evals, data analysis, or tooling integration). * Experience with distributed tracing, SLO/SLI monitoring, and chaos engineering in production environments where system failure carries direct financial or regulatory impact. Agentic Engineering * Daily operational fluency with CLI and terminal-based agent environments (Claude Code, Gemini CLI, Codex) as well as agentic IDEs (Cursor, Antigravity). * Direct experience configuring system context, building or integrating Model Context Protocol (MCP) servers, function calling, and structured domain-prompting. * Proven track record of designing property-based tests, static analysis rules, and code-review workflows specifically built to catch AI hallucinations, edge-case failures, and security vulnerabilities. * Demonstrated ability to establish team-wide AI coding norms, measure developer outcome velocity, and champion an AI-first engineering culture. Staff-level Expectations * Drive architecture decisions across team boundaries and be able to articulate tradeoffs clearly to both engineers and stakeholders. * Be able to operate under pressure and on-call for system where failure has direct financial or regulatory input * Elevate team capabilities through rigorous code reviews, design reviews, pairing, and active mentorship. * Contribute to development tooling and engineering culture initiatives. * Drive technical leadership by mentoring the team on agentic AI capabilities, accelerating feature delivery while maintaining strict code quality and reliability., * Experience developing software for financial risk management, high-frequency trading, or clearing systems. * Experience building internal developer tools, CLI extensions, or custom LLM evaluation harnesses. * Familiarity with local model deployments or fine-tuning workflows for enterprise dev environments. ## Description * Lead the architecture, design, and development of high-volume, low-latency Java applications on Google Cloud Platform (GCP) for mission-critical systems, ensuring ultra-high availability, low jitter, and thread safety. * Lead the team's shift toward agentic software engineering. Standardize toolchains, system prompts, context repositories, and agentic loops across the development lifecycle. * Build and maintain the shared agent infrastructure: repo-level agent context, MCP server integration, codebase indexing pipelines, and local developer tooling that feed deep, domain-specific context into LLM agents. * Design dynamic evaluation harnesses, automated test suites, and CI/CD guardrails specifically tailored to audit, test, and validate AI-generated code for concurrency bugs, memory leaks, and performance regressions. * Maintain and enhance high-throughput CI/CD automation pipelines to ensure seamless, secure, and reliable software delivery into production. * Mentor engineers through the workflow shift; lead hands-on workshops to train traditional software developers into proficient AI-native engineers.
