In the initial months, you'll be working closely with the team, gradually taking ownership of central components and features. Given our early stage, we're seeking versatile engineers, comfortable contributing to various aspects of the company's foundation. We value team members who delve deep into their respective domains, aiming to cultivate a team of subject matter experts. This commitment to expertise is an expectation of every team member. The backend team at amo is responsible for both server side and the backbone of the client as we believe it makes more sense to have one team handle both ends of the same topics (network, data modelling, management and synchronisation, etc)., In addition to server side development, you will participate in the evolution and maintenance of a Rust component that we share between iOS and Android and that deals mostly with networking, data synchronisation and data-oriented feature logic that benefit from being written just once. You will collaborate with iOS and Android engineers to maintain a unified codebase, enabling consistent experiences across platforms. You'll also bridge the gap between mobile development and backend infrastructure for a seamless user journey. Feature Development Participating in brainstorming sessions and discussions to design and implement features that set us apart in the market. Continuous Improvement We love learning from each other, staying abreast of industry trends and emerging technologies, bringing fresh ideas to the table. So you'll be contributing to our culture of continuous improvement, where learning and growing are integral parts of the journey. Owning your scope You will be responsible for monitoring analytics and managing system crashes. We value engineers who take ownership of their scope, and proactively address issues and triage bug fixes., To ensure that everyone is set up for success within our way of working, we work together onsite 5 days a week. ## Related Videos - [Xcode development redefAIned](https://www.wearedevelopers.com/videos/100195-xcode-development-redefained) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Scalable architecture for mobile apps](https://www.wearedevelopers.com/videos/275-scalable-architecture-for-mobile-apps) - [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) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Back(end) to the Future: Embracing the continuous Evolution of Infrastructure and Code](https://www.wearedevelopers.com/videos/440-back-end-to-the-future-embracing-the-continuous-evolution-of-infrastructure-and-code) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss) - [Dev Digest 118 - not a total recall](https://www.wearedevelopers.com/magazine/452-dev-digest-118-not-a-total-recall)
