Role overview
Software
Viktor is the AI teammate. It lives in Slack and MS Teams, connects to 3k+ tools, and understands your entire company context.
A 4-person agency uses Viktor. So does a Fortune 500 team. They @-mention it for the same reason - it just works.
The numbers speak for themselves:
- 19 people.
- $15 million+ ARR in 10 weeks after launch.
- $75M Series A by Accel + founders of Slack, ElevenLabs, Framer, Deel, and many more joining as angels.
We stay small on purpose. The leverage is the team you’d join.
What you will do
- Develop and optimize the agent runtime, including sandboxed execution, memory management, and tool orchestration for high-volume API actions.
- Ship deep integrations with tools like Salesforce, Stripe, and HubSpot, ensuring they work flawlessly on real customer data from day one.
- Manage container orchestration and infrastructure on Modal to maintain high performance and cost-efficiency while scaling past 1.2M tool calls daily.
Who this is a fit for
- Proven experience building or modifying AI agent harnesses with a deep understanding of agentic coding workflows and eval infrastructure.
- Fluency in Python for backend agent logic and TypeScript/React for product surfaces, with the ability to move across the full stack.
- Possesses a ship-today mentality with the technical judgment to solve complex reliability issues and prevent hallucinations in production at scale.
Why this role is remarkable
- Join the fastest-growing startup in the world, hitting $15 million ARR in just 10 weeks with a elite team of only 19 people.
- Backed by a $75M Series A from Accel and iconic angels including the founders of Slack, ElevenLabs, Framer, and Deel.
- Experience extreme ownership and zero layers, working directly with founders to build the agent runtime everyone else will try to copy.
