The Opportunity

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.

Requirements

What We're Looking For

- 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.

Who Thrives Here:
• Builders who love creating something from nothing and aren't afraid of rolling up their sleeves
• Fast movers who navigate ambiguity with confidence and iterate at speed
• Problem solvers who are energized by complex, evolving challenges
• Collaborators who can influence without authority and build strong cross-functional relationships
• Data enthusiasts who let evidence drive decisions, not opinions
• Mission-driven professionals passionate about fighting fraud and protecting customers
