Mission
We are building a mobile-first passive investing app on HyperEVM. Our software handles real user funds and there is no undo button on-chain. Reliability and safety are core product features.
We do not run manual QA as a primary strategy. This role builds automated testing and quality gates that catch failures in CI before they reach users
What you will do
You will build and maintain an automated defense system for our highest-risk flows:Wallet connectionUSDC deposit and withdrawPortfolio selectionRebalance and risk guardrailsveTMAI membership gating
Stack
Mobile automation: Maestro (YAML-based flows for mobile UI and WebViews)
Smart contract testing: Foundry (unit tests, fuzzing, invariants)
Web automation: Cypress (secondary coverage for the read-only web dashboard)
CI/CD: GitHub Actions
Core code: TypeScript (React Native) and Solidity (ERC-4626 vaults)
Requirements
Must-haves
You are engineering-first. You write automation as production-quality code, not record-and-playback scripts.
Experience with at least one mobile E2E tool: Maestro, Detox, or Appium.
Comfortable with CI/CD and GitHub Actions workflows.
Strong debugging habits: You read logs, isolate root cause, and fix determinism issues.Clear written communication and consistent progress updates.
Nice-to-haves
DeFi familiarity: ERC-20 approvals, wallet signatures, and basic transaction states (submitted, confirmed, reverted).Foundry experience (or strong Solidity testing instincts).Experience testing React Native apps with WebViews.Experience shipping in a fast-moving startup environment.
Interview process
Portfolio review: We review your GitHub and look for evidence you built automation, CI, or test infrastructure that shipped.
Take-home build: We provide a simple React Native build and ask you to produce a working Maestro flow plus a minimal CI workflow.
Technical walkthrough: You explain your selector strategy, wait strategy, failure handling, and how you would scale coverage.

Send: GitHub link (or a code sample)

How do I get a job at DeFi?
Getting a job in the DeFi (decentralized finance) industry can be a competitive process, but there are a few steps you can take to increase your chances of finding a job in this field:
- Build up your skills and knowledge: To work in DeFi, you'll likely need to have a strong understanding of blockchain technology, as well as other related technologies such as smart contracts and cryptocurrency. Consider taking online courses or earning a degree in a relevant field to build up your skills and knowledge.
- Network with industry professionals: Attend meetups and conferences related to DeFi and make connections with professionals in the industry. Networking can be a valuable way to learn about job openings and get your foot in the door at a DeFi company.
- Create a strong online presence: Many DeFi companies will look at your online presence (such as your LinkedIn profile and personal website) when considering you for a job. Make sure to showcase your skills and accomplishments online and keep your profile up to date.
- Apply for relevant job openings: Keep an eye out for job openings at DeFi companies and apply for positions that align with your skills and experience. Apply for DeFi Jobs without Experience. Tailor your resume and cover letter to the specific job you're applying for and highlight any relevant experience or skills you have.
- Consider internships or volunteer work: DeFi Internships or volunteer work can be a great way to get your foot in the door and gain valuable experience in the DeFi industry. Many companies also offer internships to students, so consider applying for an internship if you're still in school.
- Be persistent: keep trying if you don't get a job right away. It can take time to find the right opportunity, but with the right skills and determination, you can land a job in the DeFi industry.
