CAST AI is a cloud automation company founded in 2019 that cuts Kubernetes cost and operational load without asking teams to change their applications. Its platform continuously analyses running workloads and rebalances them onto the cheapest suitable instance types, spot capacity and node sizes across Amazon Web Services, Google Cloud and Microsoft Azure, typically halving compute spend. Headquartered in Miami, Florida with engineering in Lithuania, it has expanded from cost optimisation into Kubernetes security posture, application performance automation and routing for large language model traffic.

About us

Kimchi  - Cast AI's open-source AI inference platform for teams running serious agentic coding workloads. We're building the routing, harness, and infrastructure layer that makes owning your AI coding stack actually viable - without the cloud bill to match. We're early, moving fast, and developer trust is how we win.

The company behind Kimchi

2,100+ companies - including Akamai, BMW, Cisco, and HuggingFace - trust Cast AI to run Kubernetes and AI workloads at scale without manual intervention.

In January 2026, we hit unicorn status (valuation $1B+), We operate across 34 countries and we're growing fast.

Join us as we build the future of autonomous infrastructure.

Responsibilities:

  • Build things publicly with Kimchi - tutorials, demos, integrations - that show developers how to solve real problems. Think live build logs, OSS integrations, or benchmarks you'd want to read yourself.
  • Be the voice of the the developer community: Discord, GitHub discussions, Reddit, HN - be present where developers are already talking about the problems we solve
  • Be the structured feedback loop between dev community and product - synthesize what you're hearing into actionable signals for the product team. 
  • Write technical content that ranks and spreads: setup guides, benchmark breakdowns, comparison posts, integration walkthroughs
  • Speak at conferences, meetups and run workshops - representing Kimchi as a technical peer
  • Identify where new users get stuck and advocate hard for fixes
  • Help shape Kimchi's voice in the developer community - what we stand for, what we say when there is trending news in the market 

Requirements:

  • You've built real software and can talk about it credibly - ideally you've used agentic coding tools and have opinions about them
  • You're a strong technical writer - you can explain complex things clearly and make them resonate with the developer audience
  • You're comfortable being the public face of a technical product: blog posts, talks, live demos, community threads
  • Huge plus: You'd have tested and found problems Kimchi solves interesting -  before this job posting even existed
  • Bonus: you've worked in or around Kubernetes, LLM inference, or developer tooling

What’s in it for you?

  • Enjoy a flexible, remote-first global environment.
  • Collaborate with a global team of cloud experts and innovators, passionate about pushing the boundaries of Kubernetes technology.
  • Equity options.
  • Get quick feedback with a fast-paced workflow. Most feature projects are completed in 1 to 4 weeks.
  • Spend 10% of your work time on personal projects or self-improvement. 
  • Learning budget for professional and personal development - including access to international conferences and courses that elevate your skills.
  • Team-building budget and company events to connect with your colleagues.
  • Equipment budget to ensure you have everything you need.
  • Extra days off to help maintain a healthy work-life balance.
