Backend Middle PHP Developer at Genesis Group AG — NeverHard

🌍 We’re Hiring: Backend Middle PHP Developer 📍 Location: Remote 💡About Us Yesim is an international eSIM provider with 7+ years of experience in delivering secure, seamless connectivity anywhere in 200 countries around the world. We specialize in fast, secure, and global connectivity through advanced eSIM mobile solutions for 3+ million active users. Our innovative app allows to manage multiple eSiMs within a single account - allowing users to effortlessly juggle several plans and share connectivity. ✨ About the Role You will work within the backend team under the guidance of a Backend Tech Lead and report into the CDO (Chief Development Officer). You are expected to work independently on complex tasks, participate actively in code reviews, and deliver tested, production-ready code within a structured Scrum process. This is a hands-on engineering role. You write code, you own quality, you ship. 📝 Responsibilities Engineering & Code Quality Write clean, maintainable PHP code in line with SOLID principles—not as theory, but as daily practice. Design, write, and maintain unit and integration tests. Product quality starts before production: we prevent issues early rather than passing their consequences on to customers. Participate in code reviews through GitHub Pull Requests. Use PHPStan, PHPUnit, CS Fixer, and linters as part of the CI pipeline. Important but routine checks are automated, allowing the team to focus on higher-value engineering decisions. Contribute to the gradual decomposition of a legacy monolith into a cleaner, more modular architecture. Take ownership of your deliverables throughout their full lifecycle: from design and implementation to monitoring results in production, resolving incidents, and analysing root causes. Delivery & Collaboration Work within sprint planning, daily standups, and retrospectives Deliver predictably within sprint commitments – flag blockers early, communicate proactively Collaborate with Tech Lead on technical decisions, architecture discussions, and estimation Support teammates through code reviews, knowledge sharing, and pair debugging Follow Definition of Ready and Definition of Done – stories enter sprints prepared and leave sprints tested Modern Tooling & Continuous Improvement Be open to adopting and learning modern development tools, including internal team solutions Propose improvements to codebase, tooling, and processes when you see a better way Contribute to CI/CD pipeline improvements and deployment process optimization We value engineers who ask "how can this be done better?" and then actually do it CI/CD & Process Work within GitHub Actions CI/CD pipelines Follow branch protection rules: PRs require approvals, no direct pushes to production Keep documentation current – architecture decisions, runbooks, technical debt notes Create and maintain technical documentation, including API specifications, data-flow diagrams, and onboarding materials. When building or changing a system, communicate blockers proactively. Collaborate with the Tech Lead on technical decisions, architecture discussions, and task estimation. Support teammates through code reviews, knowledge sharing, and collaborative debugging. Follow the Definition of Ready and Definition of Done: work enters a sprint well prepared and leaves it tested. 📩What We’re Looking For 3+ years of professional PHP development (mixed environments: framework-based and pure PHP) PHP as it is (vanilla) – solid working experience (our main stacks are frameworkless) Laravel – working experience (not all our stacks use it) MySQL – query optimization, schema design, migrations PHPUnit – you've written tests and you believe in them, not just on your CV SOLID, DRY, KISS – you can explain these and demonstrate them in code review Experience writing and maintaining technical documentation – API docs, architecture overviews – as part of regular workflow, not as a separate task Git & GitHub – branching strategies, PR workflows, conflict resolution REST API design – you've built APIs that other teams or services consume Docker – local development, staging environments Strong understanding of code review culture – you give constructive feedback and receive it well English – professional working level (documentation, PR comments, technical discussions) Russian – minimum A1 (team communication language) ⭐️ Nice-to-Haves ClickHouse or other analytical databases Experience in telecom, eSIM, or SaaS products Exposure to Scrum/Agile delivery frameworks (Jira, sprint planning, retrospectives) ISO 27001 awareness or experience working in security-conscious environments 🎁 What We Offer Ownership of complex features and components from day one Direct collaboration with Tech Lead and CDO – your technical input matters Adopting modern engineering culture: modern tools and internal solutions to make work faster and smarter together
