Coding AI IDEs reinvented how software is written. Catio is reinventing how software is decided and governed. This is critical in an AI-first environment.
Catio is the Architecture IDE — the control plane for modern software. It gives engineering leaders the system-level intelligence they’ve always lacked. While Coding AI IDEs like Claude Code and Cursor turbocharge coding, the real bottleneck is now upstream: deciding what to build, what to modernize, and how to move fast with architectural confidence. That’s where Catio comes in.
Our AI platform builds a living architecture model from production reality, aligns business and product goals with technical context, and uses our reasoning agent — Archie — to generate decision-grade insights, strategic modernization and optimization plans, and execution-ready feature specs and designs. Catio amplifies architects and engineering leaders the way coding copilots amplify developers. See this Demo.
Backed by world-class investors like Eniac Ventures and RRE, and advised by leading enterprise technology operators from Dropbox, Akamai, Databricks, and Cerner, Catio is partnering with hyperscalers and visionary enterprises to define a new category in software and infrastructure.
This is a high-impact, deeply technical individual contributor role where you’ll be designing and building the intelligent backend systems that power Catio’s AI-first platform for cloud-native architecture planning. You’ll be working at the intersection of distributed systems, data pipelines, and ML infrastructure to power our agentic AI recommendations and architecture insight workflows.
This is not your average backend role—it demands systems thinking, architectural curiosity, and a passion for enabling deep visibility and expert automation for modern tech stacks. You’ll help bring to life our vision of becoming the go-to Copilot for tech stack architecture, by contributing to the intelligence layer that understands infrastructure, models system behaviors, and suggests improvements that drive engineering and business ROI.
We’re looking for a rising star IC—someone who is technically rigorous, thrives in ambiguity, and wants to own meaningful product and platform depth from day one. If you’re someone who has built 0→1 systems, consistently raised the bar in engineering quality, and believes in the power of great tooling for tech leaders, this is your platform. 🚀
Build scalable backend systems powering our observability, architecture modeling, and recommendation engines—leveraging data pipelines, microservices, and system modeling techniques.
Integrate AI/ML workflows by collaborating with AI engineers to embed LLM-based and multi-agent architecture intelligence within the platform, enabling rich architecture recommendations and generative planning.
Contribute to core architecture capabilities: Help identify key architectural patterns and best practices, build backend services that reflect architecture decisions and evolution, and ensure Catio provides actionable visibility for our users.
Optimize performance and maintainability: Implement monitoring, fault-tolerant workflows, and observability layers for mission-critical services.
Collaborate cross-functionally: Work with product managers, AI researchers, and technical leadership to translate requirements into robust platform capabilities.
Learn and inform: Contribute to a high-performing engineering culture by sharing learnings and taking initiative to inform other team members where relevant.
4+ years of experience in backend engineering at top-tier startups or technology companies, although we are not opposed to less experienced candidates with outstanding expertise.
Proven track record of building scalable, production-grade systems, ideally in 0→1 product environments.
Expertise in modern backend languages and frameworks (Go, Python preferred), with a passion for clean, idiomatic, maintainable code.
Deep knowledge of distributed systems and microservices architectures, with practical familiarity in observability and DevOps tooling.
A systems-thinking mindset and a passion for solving architecture and infrastructure challenges—especially for the cloud-native space.
Strong aptitude for performance tuning, debugging, and technical architecture design.
Demonstrated ability to leverage AI-assisted development (e.g. Cursor, ChatGPT, Claude Code), with an openness to leveraging emerging technologies.
A high-trust personality with a growth mindset—able to collaborate across teams, share context, and own outcomes.
Academic strength in Computer Science or related field; graduate-level education is a plus.
Category Creation
We are defining a new layer in the modern software stack — the system of work for architectural reasoning. This is not incremental tooling. It’s foundational.
Cutting-Edge AI
Catio sits at the intersection of AI, software, infrastructure, and enterprise systems — empowering architects and tech leaders, the way coding copilots empower developers.
Ground-Floor Impact
You will help shape how this product is sold, positioned, and adopted in the market. Your work will directly influence the trajectory of the company. You will liaison the brand and the trust of Catio into the market.
Team Pedigree & Vision
