This is a high-autonomy product engineering role. You should be comfortable going from a blank page to a deployed prototype, then hardening the parts that need to become production surfaces. The work may shift from a partner demo to a React Native integration to a documentation rebuild to a new product workflow. The common thread is ownership: you can understand the goal, design the path, ship the work, test it, explain it, and remain accountable after it goes live. This is not a narrow frontend role and not a generic CRUD backend role. The strongest candidates will enjoy building across the stack in a security-sensitive domain where clarity, speed, and correctness all matter. What You Will Own * Build customer-facing prototypes and product demos that help partners understand what is possible with Silence technology. * Develop and maintain web and mobile product surfaces using React, Next.js, React Native, TypeScript, and related tooling. * Build backend APIs, integration services, and developer-facing surfaces that expose cryptographic capabilities safely and clearly. * Improve SDK and documentation experiences so external developers can integrate without hand-holding. * Use LLM-assisted development workflows responsibly: move fast, but read the code, understand the architecture, run the tests, and own the output. * Collaborate with cryptography, backend, product, business development, and partner teams to translate ambiguous requirements into working software. * Help establish lightweight patterns for testing, CI/CD, observability, and regression prevention across fast-moving product surfaces. What Success Looks Like * Early prototypes turn ambiguous partner or product needs into working software quickly enough to shape the conversation. * Several customer-facing demos, product features, or developer-facing surfaces move from brief to deployed artifact with clear ownership. * A React Native SDK or mobile-first integration path becomes more production-ready for a real customer or partner use case. * Developer documentation, examples, or integration guides become easier for external engineers and internal teams to use without repeated explanation. * A new product area has a clearer technical design because you translated ambiguity into a practical implementation path. * LLM-assisted development, where used, increases speed without weakening code ownership, review discipline, testing, or maintainability. ## Related Videos - [Build and Deploy a Fullstack App with Open Source Tooling](https://www.wearedevelopers.com/videos/775-build-and-deploy-a-fullstack-app-with-open-source-tooling) - [WebAssembly: The Next Frontier of Cloud Computing](https://www.wearedevelopers.com/videos/972-webassembly-the-next-frontier-of-cloud-computing) - [Rest API Antipatterns](https://www.wearedevelopers.com/videos/100208-rest-api-antipatterns) - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Navigating the Corporate Jungle: Life as a Developer in a large Company](https://www.wearedevelopers.com/videos/621-navigating-the-corporate-jungle-life-as-a-developer-in-a-large-company) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Frontend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/195-frontend-developer-salary-in-germany-2023) - [React Developer Salary [2023]](https://www.wearedevelopers.com/magazine/198-react-developer-salary-2023) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025)
