About Cor

Ever wondered what it would be like to have a product expert who knows their product, knows you, understands your use cases and is available on demand 24/7 for every software app you use?

This is the problem we work on at Cor as we build AI voice agents that make software feel less like a tool and more like a partner.

We’re starting with customer onboarding and education. Our flagship agent, Obi, is already live and handling hundreds of onboardings every month.

The software industry is going through its biggest shift yet. New tools, new experiences and new features ship faster than ever, and adoption is becoming the real bottleneck.

The winners in this new world will be the businesses that master adoption over production. We’re building a platform that makes that possible, and we’re looking for people who want to be part of it.

The Role

We’re looking for a software engineer with demonstrable experience across a broad spectrum of tech, who’s excited to work on cutting-edge AI voice tech and shape what’s next.

What you’ll do:

• Build and optimise advanced voice AI systems.
• Test and evaluate LLMs and other model performance.
• Optimise system speed, reliability, and overall performance.
• Own the full delivery of features and projects from idea to production.
• Design data pipelines and integrate with third-party systems.
• Work closely with customers to gather feedback and improve UX.
• Collaborate with the founding team on product, architecture, and culture.

You’ll have full ownership to run with your work. Everyone’s here to help when you need it, but we trust you to lead and deliver.

The Opportunity

We can’t yet offer a household name. But we can offer real ownership and the chance to build something meaningful from day one.

No hierarchies. No performance reviews. No corporate fluff. Just a tight-knit team building at the edge of what’s possible.

Our team brings together backgrounds ranging from computational physics and high-performance computing to leadership roles at successful SaaS startups and major tech companies.

We’re venture-backed, resourceful, and ready to take on the best.

Joining us means betting on a team that takes big swings and believes in building something truly transformational.

Requirements

- Experience with one of Python or Golang is essential.

- Experience with TypeScript and React is desirable.

- Demonstrated experience in startup environments.

- A willingness to learn, and to help us improve our processes.
