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.What You'll Own:Features from requirements to production: you break them down, build them, ship them, monitor themTechnical decisions within your scope, with clear trade-off reasoningQuality of your code and the areas you touchResponding to incidents and dev-escalations in your domainBuilding the new TypeScript system that will replace the legacy PHP platformMaintaining and supporting the existing PHP system throughout the transitionWhat Your Work Will Entail:1. Feature DevelopmentTake feature requests, break them into tasks, estimate, and deliver independentlyBuild the new TypeScript-based system designed to replace our existing PHP platformMaintain and support the current PHP system in parallel, until the new system is fully migratedWrite clean, tested, production-ready code that meets team standardsMake technical decisions for features and explain trade-offs clearlyMonitor your features in production — logs, metrics, alertsLeave the codebase better than you found it (refactor, document, reduce debt)2. Production Ownership & Incident ResponseRespond to dev-escalations with urgency — investigate issues, communicate findings, contribute to resolutionParticipate in incident response: at all levels, you are expected to show up, help investigate, and support resolutionL4+: Drive incident response for your domain — coordinate investigation, delegate tasks, communicate status to stakeholders, and ensure post-mortems happenWrite runbooks and keep documentation current as you buildShare on-call rotation after ramp-up period3. Code Quality & TestingWrite unit and integration tests as part of feature work, not as an afterthoughtParticipate actively in code reviews — give thoughtful feedback, act on feedback you receiveIdentify edge cases and risks during planning, not after deployment4. AI-Augmented Development (Expected, Not Optional)Use AI coding tools daily: code generation, debugging, test writing, exploring unfamiliar parts of the codebase, code review accelerationYour output should be measurably faster because of AI toolsYou understand everything you ship — AI is an accelerator, not a replacement for judgmentL3+: Help teammates develop effective AI workflows; contribute to team standards for AI tool useL4+: Set team standards for AI tool usage — evaluate what delivers real value, ensure quality isn't sacrificed for speed5. CollaborationWork closely with Product, Design, QA, and other engineersContribute meaningfully to sprint planning and technical discussionsL3+: Mentor L1/L2 engineers through code reviews, pairing, and sharing knowledgeWhat You Bring To This Role:Technical EnvironmentPrimary stack: TypeScript/Node.js for the new system you'll build, and PHP 7.4/8+ with Laravel for the existing system you'll maintain during the transition.Infrastructure: MariaDB, Redis, AWS (EC2, RDS, CloudWatch, SQS, S3), Docker, GitHub Actions CI/CDThis role requires active, hands-on TypeScript experience and past professional experience with PHP. Hands-on experience integrating payment platforms such as Stripe and PayPal is required.Expectations by Level:L1: Works on well-scoped tickets with guidance. Learning the codebase and practices. Uses AI tools to learn faster and ship more.L2: Independently owns features. Minimal guidance needed on implementation. Noticeably faster because of AI tool usage.L3: Leads small projects. Mentors L1/L2. Improves the codebase proactively. Teaches effective AI workflows.L4: Technical authority for a domain. Drives cross-team projects. Sets team AI standards. Drives incident response.Success Metrics:Early on, you'll ship your first feature to production, understand the core architecture, and get your local development environment set up. From there, you'll be independently shipping features end-to-end and contributing to code reviews. As you grow further, you'll contribute meaningfully to technical discussions and handle dev-escalations in your area.On-Call:Shared rotation (~1 week/month after ramp-up). Critical: 15 min. High: 1 hour.Our Values are:Commit to ExcellenceFind a WayHelp Each OtherKeep GrowingData FirstOur team and product are growing rapidly- we achieved YoY growth of 64% from 2022-2023, and we’re just getting started.
