Vestwell | Senior Software Engineer | HYBRID - NYC; Austin; King of Prussia, PA | https://www.vestwell.com/careers/7510610003 | $145K - $160K base + bonus & equity

I'm the hiring manager for this role. Please see the job description for details, but I'm looking for someone who is, or is able to become, proficient in backend development for a public nest.js API suite using TypeScript. We don't have any hard requirements like a CS degree or prior nest.js experience, but candidates do have to complete a TypeScript coding challenge. It's a real-world problem, no leetcode. In total, our interview process is only 3 rounds, and we move pretty quickly. We want someone who has systems design experience and good technical leadership skills. You also have to be self-motivated. We use a pull rather than push process, so work isn't assigned to people, and you have to be good at working efficiently without many hard deadlines or micromanagement.

Happy to answer any questions here! If you'd like to apply, please email shane.vierra [at] vestwell [dot] com with your resume.

Stellar is building the go-to AI voice agent platform for customer support, enabling incredibly human-like customer service over the phone. We're a young and rapidly growing startup that has already proven traction, with a number of well-known companies among our initial customers.

To see some of our AI voice agents in action, see https://www.stellarcs.ai/demo-showcase

We're looking for founding software engineers to help us scale Stellar's platform globally. As one of the first members of our engineering team, you’ll play a key role in Stellar's journey and have the opportunity to help shape our architecture, engineering culture and product and engineering roadmap.

Tech stack: Go, Node.js, Typescript, React, Next.js, Encore Cloud, GCP

What you’ll do:

- Build performant APIs and backend services in Go and Typescript (Node.js)

- Develop Stellar's frontend in React, TypeScript and NextJS, to allow companies to effectively design, test, deploy and monitor their AI voice agents

- 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, resilience and data privacy

- Build API integrations with external systems to enhance the capabilities of Stellar's agents

- Help shape the early engineering culture as one of the first hires of a young and growing tech startup

Why join: you'll be joining at a pivotal time in our growth, in a role with a high degree of ownership and strong growth potential. Join a small but talented team, coming from high growth startups and scale-ups such Framer, MessageBird and Adyen.

Please stop. The way you're posting is not helping - it just makes things worse. We detached this comment from https://news.ycombinator.com/item?id=46110145 .

If the mods aren't going to enforce the rules what other options do we have? Serious question. This ad has been posted in 11/12 threads this year. Perhaps there should be a cooldown on the same posting after 3 months?

Job applicants are under enough stress as it is, they shouldn't be fooled into wasting their time applying to ghost jobs.
