Job Overview

We are looking for an experienced Senior Backend Engineer to join our engineering team. You will play a pivotal role in architecting and building high-performance, scalable microservices using NestJS.

In this role, you will tackle complex data challenges, optimize database interactions, and ensure event-driven consistency across our platform. The ideal candidate is a hands-on technical leader who loves strictly typed systems, efficient data pipelines, and clean API design. 

Key Responsibilities

• Architect & Build: Design, develop, and maintain scalable microservices using NestJS (TypeScript).
• Database Optimization: Manage complex data modeling and query optimization for high-load environments using PostgreSQL and ClickHouse.
• Event-Driven Systems: Implement and manage event-driven architectures using Apache Kafka to ensure reliable data streaming and service decoupling.
• API Management: Design and document RESTful APIs using the OpenAPI (Swagger) specification, ensuring contract-first development and seamless frontend integration.
• Real-time & Auth: Leverage Supabase for real-time subscriptions, authentication flows, or rapid prototyping where applicable.
• Code Quality: Enforce code standards through rigorous code reviews, automated testing (Jest/Supertest), and CI/CD pipelines.
• Mentorship: Mentor junior and mid-level engineers, providing technical guidance and fostering a culture of engineering excellence.

Technical Requirements

• NestJS Expert: 5+ years of backend development experience, with deep expertise in NestJS and the Node.js ecosystem.
• Relational Data: Advanced proficiency with PostgreSQL, including optimization, indexing, and raw SQL queries.
• Big Data Analytics: Production experience with ClickHouse for analytical processing and handling large datasets.
• Event Streaming: Strong experience with Apache Kafka (producers, consumers, partition strategies, and schema registries).
• Microservices: Proven track record of decomposing monoliths or building microservices from scratch (gRPC, RabbitMQ, knowledge is a plus).
• API Standards: Mastery of OpenAPI/Swagger tools to generate clients and documentation automatically.
• Supabase: Experience integrating Supabase (PostgREST, Realtime, or Auth) into a custom backend architecture.
• Testing: Strong belief in TDD/BDD, with proficiency in writing unit and integration tests.

Nice-to-Have

• Experience with containerization and orchestration (Docker, Kubernetes).
• Knowledge of Redis for caching strategies.
• Experience with Infrastructure as Code (Terraform).
• Familiarity with GraphQL.

Soft Skills

• Problem Solver: You enjoy digging into complex performance bottlenecks and solving them efficiently.
• Communicator: You can explain complex architectural decisions to non-technical stakeholders.
• Owner: You take full ownership of your features, from design to deployment and monitoring.

Why Join Us?

• Competitive Salary: We value your expertise and pay accordingly.
• Remote-First Culture: Work from where you are most productive.
• Tech-Forward: We are constantly evaluating and adopting the best tools for the job (like the stack mentioned above).
• Professional Development: Budget for courses, conferences, and certifications.
• Long Term Position: Stable and long term position.
• Flexible and Secure Payments: Via deel.com 

We are seeking a Senior Frontend Engineer who cares deeply about performance, pixel-perfect implementation, and developer experience. You will lead the development of our client-facing applications, leveraging the power of Next.js (App Router) and Payload CMS to build dynamic, content-rich, and highly scalable digital experiences.

You won't just be "slicing designs"; you will be architecting our frontend design system, making critical decisions about server-side vs. client-side rendering, and ensuring our CMS implementation is flexible for content editors while remaining type-safe for developers.
 

The Stack

• Core Framework: Next.js 14+ (App Router, Server Components)
• Language: TypeScript (Strict Mode)
• CMS: Payload CMS (Self-hosted / Cloud)
• Styling: Tailwind CSS + Radix UI / Headless UI
• State/Data: React Query (TanStack Query) / Zustand
• Testing: Cypress (E2E) & Jest/React Testing Library
• Package Manager: pnpm / Bun

Key Responsibilities

• Architecture: Lead the migration/development of applications using Next.js, optimizing for Core Web Vitals, SEO, and hydration performance.
• CMS Integration: Design and implement complex content models in Payload CMS, ensuring a seamless editing experience for non-technical teams and robust type generation for the frontend.
• Component System: Build and maintain a reusable, accessible component library using Tailwind CSS. We value consistency and utility-first CSS principles.
• Type Safety: Enforce end-to-end type safety (from CMS content to frontend props) using TypeScript and Zod.
• Performance: Proactively monitor bundle sizes, image optimization, and server response times.
• Collaboration: Work closely with Backend Engineers to define API contracts and with Designers to bridge the gap between Figma and reality.

Technical Requirements

• Next.js Mastery: Deep understanding of the App Router, Server Actions, Incremental Static Regeneration (ISR), and SSR vs. CSR trade-offs.
• Payload CMS: Experience configuring Payload collections, globals, and blocks. You know how to extend Payload with custom fields or hooks.
• Tailwind Expert: You know how to configure tailwind.config.js for theming, write custom plugins, and avoid "class soup" by componentizing effectively.
• TypeScript: You don't use any. You are comfortable with generics, utility types, and inferring types from CMS schemas.
• Modern React: Proficiency with Hooks, Context API, and composition patterns.
• State Management: Experience managing server state (React Query) vs. global client state (Zustand/Context).

Nice-to-Have

• Docker: Experience containerizing Next.js and Payload applications for deployment.
• Storybook: Experience documenting UI components in isolation.
• Monorepo Tools: Familiarity with Turborepo or Nx.
• Animation: Experience with Framer Motion or GSAP for polished interactions.
• Open Source: Contributions to the Next.js or Payload CMS ecosystems.

What We Offer

• Competitive Salary: We value your expertise and pay accordingly.
• Remote-First Culture: Work from where you are most productive.
• Tech-Forward: We are constantly evaluating and adopting the best tools for the job (like the stack mentioned above).
