Your Title: SeniorDirector of Engineering
Your Location: Hybrid – Edison, NJ HQ
You Report to: SVP of Engineering and Chief Architect
Compensation: $225,000 or more depending upon experience
At 1Kosmos, our leaders are active, builder-first contributors. We are looking for an engineering leader who stays close to the code—someone who enjoys diving into technical challenges, understanding system internals, and driving execution from the front lines through active participation in architectural design, code reviews, and hands-on problem-solving.
You possess an "always sleeveless" mindset: no task is too technical, no bug is too small, and no architecture is too complex for you to dive into. You will step into a cloud-agnostic microservices environment, gain deep context on what we’ve built, and actively drive execution, performance, security, and system evolution.
What You’ll Do:
- 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.
What you bring:
- 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.
