Skills: Python, AWS, REST, Data Analysis
Apply if you are:
* A generalist comfortable getting projects from 0 to 1
* Interested in learning about the intricacies of how our power grids are regulated and writing software to interface with them (and stabilize them).* (bonus) Familiar with ML engineering (training, deployment, features, evaluation, etc.)In this role, you will help productionize (and potentially own) our battery optimization software and create prototypes for prospective opportunities. You can’t get closer to the business logic than that because these projects inform how the battery runs and how much we are willing to pay (in rent) for new batteries!

- Fullstack Expertise: From writing impeccable React components to designing backends in Node.js, GO, Rust or Python.
2. Technical Chops
- System Design & Architecture: You know how to build services that won’t break under pressure—microservices, caching strategies, database sharding, you name it.
- Performance Focus: Terms like “high throughput” and “low latency” aren’t just buzzwords to you; they’re part of your daily vocabulary.
- Best Practices: You never skip tests, you don’t do “quick hacks,” and you treat CI/CD pipelines like your best friend.
3. Mindset & Soft Skills
- Ownership & Drive: You see problems and can’t help but fix them.

We believe in a world where every organization, from a small startup to a large enterprise, will be tokenized and traded onchain. For this world, Arrakis is building the tools to create the necessary liquidity to enable this token economy to rival and out-compete the traditional financial industry.
DeFi is at risk itself of being overcome by centralised actors however. As Ethereum’s DeFi ecosystem has become more complex, sophisticated actors have extracted more and more value known as MEV. Arrakis is working on next generation solutions at the speartip of the MEV supply chain, such as HOT AMM, to protect LPs and token issuers against this value extraction.
The role
As one of the Front End engineers at Arrakis, we’re looking for someone who is hands on but also has strong product thinking skills.

- You won’t burn time in pointless meetings. We run a planning call on Mondays and do demos on Fridays. We have ad hoc working sessions and do daily async written updates.
Requirements
- Strong proficiency in React and Next.js ecosystems
- Hands on experience with Web3 technologies (wagmi, viem, Rainbowkit)
- Extensive experience with ReactQuery for efficient data fetching and state management
- Advanced knowledge of Typescript, including complex type definitions and best practices
