About Stellar

Stellar's AI voice agent platform allows companies to effectively design and operate AI agents for customer support over the phone, with Stellar's agents completing up to 70% of customer requests without requiring any human assistance.

To get an idea of our product, you can check out our platform demo's here.

We already have significant traction, and are currently working with a number of reputable companies for which the first AI voice agents have been created. We have a long list of companies across different continents interested in our platform, and are now growing the team to be able to meet the demand and further build out our platform.

Our product distinguishes itself through:

• Remarkably human-like conversations at extremely low latency
• An AI agent framework built for enterprise standards, with sophisticated safety mechanisms built-in
• An intuitive agent editor interface, that makes it easy for companies to iterate on their agents.
  

We’re ambitious, product-obsessed, and laser-focused on solving real-world problems. We believe in giving our team members the trust, ownership, and tools to make an outsized impact from day one.

About the role

Stellar is looking for founding software engineers (accepting applications ranging from medior to senior+ level) to help us scale our voice AI agent platform.

We're looking for team members who are able to work across the entire stack - from building scalable enterprise-grade backend services in Go and Node to crafting intuitive user interfaces in React and TypeScript.

As one of the first members of our engineering team, you’ll play a vital role in Stellar's journey and have the opportunity to help shape our architecture, development practices, and product and engineering roadmap.

This role is based out of our Amsterdam office. We value in-person collaboration and do not offer remote-only roles, but can accommodate up to 2 days remote per week.

‍

Technology stack

• Golang
• Typescript
• Node.js
• React
• Next.js
• Encore Cloud
  

If you're strong in at least some of these, entrepreneurial and eager to learn, we'd still love to talk.

‍

What you'll do

• Build performant, enterprise-grade APIs and backend services in Go and Node.js
• Develop Stellar's Studio frontend in React, TypeScript and NextJS
• Design a scalable, fault-tolerant system architecture that can handle large volumes of concurrent real-time audio conversations & agent interactions while maintaining low latency
• Work on Stellar's AI agent framework, at the intersection of software engineering and AI engineering
• Design and implement a platform that meets enterprise standards in terms of security, compliance and data privacy
• Build API integrations with systems used by our customers (e.g., CRMs, customer support systems, internal APIs) to enhance the capabilities of Stellar's agents
• Improve platform performance, observability, and developer experience
• Help shape the early engineering culture for a young and growing tech startup, and help onboard and coach future team members

‍

Who you are

• At least 4+ years of professional experience building and shipping software to production (we're accepting applications ranging from medior to senior+ level)
• Comfortable with Go, Node.js, Typescript and/or React (bonus if you know all four)
• Experience building across the full stack, from frontend to backend to infrastructure level
• Proactive, self-directed, and excited to work in a fast-paced startup environment with a high degree of autonomy
• Fluent in English
• EU work authorization (we are not able to offer visa sponsorship)

‍

You'll thrive here if you

• Are a self-starter looking for a role with a high degree of ownership, at a young and fast-growing company
• Enjoy working across the full technology stack, rather than specialising on a smaller portion of our codebase
• Enjoy solving hard engineering problems at the intersection of software engineering and AI engineering (including low latency (voice) infrastructure and designing enterprise-grade systems)

‍

Why Stellar

You'll be joining at a pivotal time in our growth, as Stellar has already proven strong traction and is currently introducing its AI voice agents at multiple reputable companies, with many more companies in the pipeline. As a founding software engineer, you'll have a large degree of ownership, a meaningful impact on what and how we build, and a clear path to grow along with the company as we further scale up the team in the near future. You'll also have an opportunity to work on software at the bleeding edge of AI capabilities.
