About Ventus AI
Ventus AI is building the next generation of AI Agents - intelligent, computer-using agents that handle the complex, manual workflows that sit at the heart of every enterprise. We specialize in automating the "messy middle" of operations: the high-variance tasks that traditional automation and API-based solutions cannot touch.
Our AI Agents Operate software like humans do (navigating portals and handling MFA), Communicate with human colleagues via Slack/Teams, Learn from existing SOPs, and Deliver finished work. Backed by Andreessen Horowitz (a16z), we are turning agentic AI into the primary infrastructure for the modern workforce.
The Role
We are looking for a Founding Software Engineer to build the core engine behind our AI Agents. This is not an experimental R&D role; you will be building and maintaining robust production systems that interface with real-world environments full of edge cases, ambiguity, and operational complexity.
You will work directly with the co-founders to set technical direction, establish engineering best practices, and ship at high velocity. Because you will be building the "brain" and "hands" of our agents, you will have a front-row seat to how customers interact with AI—an invaluable experience if you intend to start your own venture in the future.
What You'll Do
- Agent Orchestration: Design and build mission-critical infrastructure for agent memory, logging, security, and observability.
- Production-Grade Code: Write robust Python (and some TypeScript) to power low-latency, fault-tolerant, agentic workflows that can recover from UI changes and session timeouts.
- Human-in-the-Loop: Build the communication layer that allows AI Agents to pro-actively flag exceptions and collaborate with humans in real-time.
- Systems Reliability: Own the end-to-end reliability of agents navigating "messy" legacy software without APIs.
- Foundational Architecture: Make key decisions on testing, CI/CD, and monitoring pipelines from scratch.
- Industry Diffusion: Work on a platform designed to scale across diverse industries—from Healthcare and Insurance to Finance and beyond.
You Might Be a Fit If You…
- Are a Builder: You have built and maintained production systems end-to-end—from initial architecture to deployment and refactor.
- Thrive in High-Autonomy: You enjoy ambiguous environments where you are trusted to figure out the "how" and "why."
- Have Deep Technical Comfort: Proficiency with Python (async, testing, deployment) and modern development tooling is essential.
- Balance Speed and Simplicity: You understand the trade-offs in system design and can build systems that are simple yet resilient.
- Have a Founder Mindset: You approach code with a sense of ownership, urgency, and comfort with the "chaos" of a 0-to-1 startup.
Bonus Points For
- Experience with agentic frameworks, browser automation (Playwright/Puppeteer), or computer-use agents at scale.
- Experience in secure data processing (SOC 2, HIPAA environments).
- Prior startup/founding experience or significant open-source contributions.
Why Join Us?
- Real Impact: We have real customers and a product that solves tangible, multi-hour manual bottlenecks.
- Zero Bureaucracy: Just you, the co-founders, and the code.
- Founder Track: We explicitly support engineers who want to learn the "business" of startups, providing direct exposure to customer discovery and product-market fit.
- Compensation: We offer a competitive cash package and significant equity upside, reflecting your role as a founding member of the team.
