**Helium is building Self-Improving Software**: AI that automatically generates & tests new software experiences to lift revenue. We’re…
* **Talent-dense** (8 people, 6 engineers, 75% ex-founders)
* **Well-funded** ($6M from Google & Leaders from OpenAI)
* **Fast-growing** (Serving tens of millions of AI experiences per day for top consumer companies).
AI has created a once-in-history opportunity, and we’re here to win, because of that…
* **🔴 We work hard — In-Office Monday–Friday + often push through weekends 🔴**
# **What You’ll Do**
You’ll own big chunks of our AI Experience Generation product serving millions of users per day, including…
* Adding new features to the front-end Next.js application and deploying scalable Golang code that serves thousands of requests each second globally.
* Tune/Optimize/Load test our servers as we 10x our growth from tens of millions to hundreds of millions of users per day.
* Designing data systems and ML training infrastructure that power automated experimentation at scale.
* Work directly with founders _and_ customers to design, implement, and deliver the best experiences!
* Wearing a lot more hats than listed above 👷.
# **What We’re Looking For**
* Keen problem solving skills: you are able to cut down ambiguous problems down to first principles and deliver a working solution.

* Experience working directly on user-facing products: you are able to figure out and understand what the user needs, including talking to customers
* Stellar cross-functional communication skills: you are able to adapt to our ways of working and be an efficient/effective communicator.
* Owning features end to end: you’ll write your own PRDs/quick specs when necessary, and you test your features end to end to make sure they work and satisfy the requirements
* Experience scoping, designing, and running complex multi-engineer projects
* Experience managing or mentoring engineers before
# **Nice To Haves**
* Experience with ML/AI/LLM integration in applications
* Experience building scalable backend systems with very demanding SLAs
* Background working with design tools, chat experiences, or vibe coding tools
* Previous experience founding or working at a high-growth startup
# **Reasons This Role Might Not Be A Fit**
* You want to work 9-5
* You avoid Cursor or AI coding tools.
* You can only operate on well-written specs, or feel uncomfortable designing new experiences from scratch.
* You don’t want to talk to customers.
# **Our stack:**
* Next.js (React/Typescript), Zustand
* AI (vercel) SDK
