Location: Remote ( Europe / LATAM) Job Overview: Full-ownership software engineer responsible for building a new system in TypeScript that will replace our existing PHP system, while maintaining the current PHP system throughout the transition. This is not a hand-off role — you take a problem from requirement to production and own it there. You'll work across both stacks, make technical decisions, and be accountable for what you ship. We expect you to use AI coding tools as a core part of how you work. Not occasionally — daily. Your velocity, code quality, and problem-solving should reflect effective AI tool use. What we care about is judgment: understanding what you ship, making the right decisions, and knowing when to push back on AI output. This description applies across experience levels (L1–L4). Interview depth and expectations are calibrated to your level. Tasks What You'll Own: Features from requirements to production: you break them down, build them, ship them, monitor them Technical decisions within your scope, with clear trade-off reasoning Quality of your code and the areas you touch Responding to incidents and dev-escalations in your domain Building the new TypeScript system that will replace the legacy PHP platform Maintaining and supporting the existing PHP system throughout the transition What Your Work Will Entail: 1. Feature Development Take feature requests, break them into tasks, estimate, and deliver independently Build the new TypeScript-based system designed to replace our existing PHP platform Maintain and support the current PHP system in parallel, until the new system is fully migrated Write clean, tested, production-ready code that meets team standards Make technical decisions for features and explain trade-offs clearly Monitor your features in production — logs, metrics, alerts Leave the codebase better than you found it (refactor, document, reduce debt) 2. Production Ownership & Incident Response Respond to dev-escalations with urgency — investigate issues, communicate findings, contribute to resolution Participate in incident response: at all levels, you are expected to show up, help investigate, and support resolution L4+: Drive incident response for your domain — coordinate investigation, delegate tasks, communicate status to stakeholders, and ensure post-mortems happen Write runbooks and keep documentation current as you build Share on-call rotation after ramp-up period 3. Code Quality & Testing Write unit and integration tests as part of feature work, not as an afterthought Participate actively in code reviews — give thoughtful feedback, act on feedback you receive Identify edge cases and risks during planning, not after deployment 4. AI-Augmented Development (Expected, Not Optional) Use AI coding tools daily: code generation, debugging, test writing, exploring unfamiliar parts of the codebase, code review acceleration Your output should be measurably faster because of AI tools You understand everything you ship — AI is an accelerator, not a replacement for judgment L3+: Help teammates develop effective AI workflows; contribute to team standards for AI tool use L4+: Set team standards for AI tool usage — evaluate what delivers real value, ensure quality isn't sacrificed for speed 5. Collaboration Work closely with Pr
