- Lead from the Front: Manage, mentor, and elevate a mid-sized engineering team while remaining deeply technical and hands-on in code, system design, and infrastructure.

- Master Existing Architecture First: Take full ownership of existing architectures. Deeply understand the whybehind our current design decisions before making tactical shifts or introducing new paradigms.

- Build Real Agentic Systems: Work hands-on with our agentic stack (AWS Bedrock / Python / Node), going far beyond basic LLM prompts or chatbots. Open the hood to optimize agent workflows, orchestration, reliability, and security.

- Drive Performance & Security: Maintain a relentless focus on low latency, high throughput, platform resilience, and enterprise security across our cloud-agnostic microservices topology.

- Own Delivery & Reliability: Partner with product and QA leads to ensure clean, reliable, and zero-downtime deployments.

- Foster a Zero-Ego Culture: Build a collaborative environment where ownership is non-negotiable, and execution speaks louder than slides.

- 10+ years of software engineering experience with recent, hands-on engineering leadership (Director / VP level in high-growth B2B SaaS).

- Core Microservices Stack: Deep, practical experience in Node.js (90% of our stack) alongside Java or GoLang.

- Cloud & Infrastructure: Hands-on mastery of containerized, cloud-agnostic environments (Kubernetes, AWS).

- Applied Agentic Experience: Demonstrated experience building and operationalizing autonomous agents and agentic workflows (experience with AWS Bedrock is a huge plus).

- Security-First Mindset: Deep appreciation for platform security, identity management, compliance, and secure software development practices.

- Leadership Style: Proven track record of both building 0-to-1 systems and taking ownership of mature, inherited codebases.
