The Impact You'll Make

Our engineering velocity is compounding. We need a senior engineer who can design and ship end-to-end product features across the stack—Ruby on Rails / NestJS on the backend and Next.js on the frontend—while mentoring teammates and upholding elite code quality.

What You'll Do

• Design & build scalable web applications using Next.js (SSR/SSG, routing, performance), NestJS, and Ruby on Rails (conventional MVC, ActiveRecord, caching).
• Own features end-to-end: database schema, domain modelling (incl. Sequent for CQRS/ES), API design with Grape and REST/GraphQL, UI/UX, CI/CD, and production rollout.
• Integrate with third-party services (Stripe, Firebase, Razorpay, etc.) and internal micro-services.
• Write clean, maintainable, well-tested code in TypeScript and Ruby, leveraging unit, integration, and e2e tests.
• Profile & optimize performance across client and server, ensuring sub-second page loads.
• Automate delivery via GitLab pipelines, containerization, and infrastructure-as-code (Terraform / Pulumi).
• Mentor engineers through code reviews, pair programming, and architecture discussions.
• Collaborate remotely with Product, Design, and Growth teams to convert vision into shippable increments.

Must-Have Technical Skills

• Ruby & Ruby on Rails (advanced)—idiomatic Ruby, MVC, ActiveRecord, caching, background jobs.
• NestJS (advanced)—modular architecture, decorators, guards, interceptors, dependency injection.
• Grape—lightweight RESTful API micro-framework for Ruby services.
• TypeScript & modern JavaScript (ES2022+) mastery.
• Relational databases (PostgreSQL preferred) and ORMs (ActiveRecord, Prisma, TypeORM).
• API design & integration—REST and/or GraphQL.
• Testing—RSpec, Jest, React Testing Library, Supertest, Cypress or Playwright.
• Version control & CI/CD—Git, GitLab/GitHub Actions, semantic release, automated pipelines.
• Debugging & observability—Rails console, Chrome DevTools, Node inspector, logging, metrics, tracing.

Nice-to-Have / Bonus Points

• Sequent (CQRS / Event-Sourcing)—command and query separation, aggregates, projections.
• Next.js (advanced)—SSR, SSG, dynamic routing, Image & App Router, performance tuning.
• Cloud: GCP strongly preferred (Cloud Run, GKE, Firestore, Pub/Sub); AWS or Azure acceptable.
• Container orchestration: Docker, Kubernetes, Helm.
• Serverless & edge runtimes: Vercel, Cloudflare Workers.
• Frontend extras: React Native, Expo, Tailwind CSS, Storybook.
• Backend extras: Micro-services, event-driven architecture, GraphQL Federation.
• Domain familiarity: EdTech, SaaS, subscription billing.
• Analytics & experimentation: Mixpanel, Amplitude, A/B testing frameworks.

Soft Skills & Mindset

• Founder-style ownership: you see problems, you fix them.
• Excellent written & spoken English; can communicate async, annotate PRs, and draft RFCs.
• Comfortable collaborating across product, design, and backend teams in a 100% remote setup.
• Bias for action, data-driven decision making, and continuous improvement.

Minimum Qualifications

• 5+ years of professional experience building applications, including at least large-scale B2C apps in production.
• Demonstrated success shipping to millions of users globally.
• Proven expertise in the Must-Have skills listed above.
• Track record of writing clean, testable, and maintainable code and running code reviews.
• Comfortable working autonomously in a fully remote environment.
