Software Engineer (Mid–Senior), Voice AI

Location: Hybrid, Melbourne (Collingwood startup hub)

About Cor

What if talking to software felt like talking to the smartest person in the room?
At Cor, we’re building AI voice agents that make software feel less like a tool and more like a trusted expert. Our flagship agent, Obi, is already live with fast-growing SaaS companies, transforming how they onboard and educate customers.

We’re early, funded, and moving fast. The next decade belongs to teams building at the edge of AI. That’s where we live.

Why You Should Care

• Work on problems few teams in the world are touching – advanced voice AI, LLM optimisation, real-time performance.
• Build with founders, not layers – direct access, full ownership, no corporate drag.
• Be in the room – our Collingwood space is packed with ambitious startups, investors, and builders.
• Shape the future – AI professional services will reshape software, and you’ll be one of the people making it happen.

What You’ll Do

• Architect, build, and optimise voice AI systems.
• Test and refine LLMs, pipelines, and integrations.
• Own features end-to-end – from sketch to production.
• Work directly with customers to turn feedback into product.
• Collaborate daily with the founding team on product and culture.

What We’re Looking For

• Strong experience in Python or Go.
• Bonus points for TypeScript/React.
• A track record in startups or scrappy teams.
• Comfort using AI tools to make your work faster and sharper.
• Hunger to learn, bias for shipping, and the ability to flex your opinions to fit the team and environment.
• Adaptability: you know how to navigate ambiguity and thrive in fast-changing conditions.

(Note: We’re not training models. We’re focused on applied AI - building real products on top of LLMs.)

What You’ll Get

• Meaningful equity (0.25–0.5%): not a token gesture, but real ownership at an early stage where growth has outsized upside. The next round could multiply today’s value in ways late-stage options never can.
• A competitive startup salary, balanced with ownership.
• Real responsibility and influence from day one - whether mid-level or senior.
• A hybrid setup in a vibrant startup hub.
• The chance to look back in 5 years and say, “I was there when this started.”
