    We are looking for a strong, productive engineer to work directly with our Lead Engineer and CTO.

     

    The role is backend-focused, with significant responsibility for asynchronous processing and integrations, while also implementing frontend integrations in React / Next.js, including GraphQL queries, mutations, and UI components (minor effort).

     

    This is not an entry-level role. You are expected to be comfortable working with TypeScript, NestJS, and React / Next.js in production, within an AWS-based environment. You’ll work with the following technologies:

     

    Backend

    • Node.js, TypeScript, NestJS
    • Event-driven patterns
    • GraphQL (Apollo Server) as BFF 
    • PostgreSQL (MicroORM), Redis

    Async & Messaging

    • RabbitMQ
    • Producers, consumers, retries, idempotency, message durability 

    Frontend

    • GraphQL (Codegen, Apollo Client)
    • Ant Design, SCSS Modules

    Infrastructure

    • AWS (EKS), Cloudflare
    • Terraform

    • Design and implement GraphQL resolvers and schemas used directly by the frontend.
    • Build and maintain integrations with external systems (CRMs, vendors, APIs), including authentication, retries, and failure handling.
    • Implement frontend integrations in React / Next.js: write GraphQL queries and mutations and connect them to UI components.
    • Provision and use infrastructure resources required by your features using Terraform (you don’t own infra, but you use it).
    • Ensure production readiness: logging, tracing, and tests where they matter.

    Requirements

    • 4+ years of professional engineering experience.
    • Strong hands-on experience with TypeScript and Node.js.
    • Production experience with NestJS and GraphQL.
    • Comfortable working with React / Next.js beyond basic UI changes.
    • Experience integrating with third-party APIs, including OAuth and rate limiting.
    • Practical understanding of AWS and ability to read and work with Terraform.
    • Security-aware mindset when working with user data and identities.

    Nice to Have

    • Experience with Salesforce or other enterprise CRM APIs
    • Experience with authorisation flows, token and session management, OAuth 2.0
    • Experience working on projects with strict compliance requirements (e.g. HIPAA, SOC 2, ISO 27001).
    • Interest in or experience with DevOps or information security

    What We Offer

    • Direct collaboration with the Lead Engineer and CTO.
    • A greenfield system with no legacy constraints.
    • High ownership and minimal process overhead.
    • Fully remote work.
    • High-end MacBook (M4 Pro) after the trial period.
    • Relocation support to Australia after long-term collaboration.

    • Solid understanding of web fundamentals: HTTP, browser rendering, SPA architecture.
    • Experience with SQL databases, basic data modeling, and queries.
    • Hands-on experience with testing (unit/integration) and CI/CD pipelines.
    • Comfortable working independently and owning features end to end.
    • Intermediate or higher level of English, fluent in Ukrainian or Russian. 
       

    Nice-to-have

    • Experience with Docker and basic Kubernetes concepts.
    • Familiarity with event-driven systems and message-based architectures.
    • Exposure to cloud platforms (AWS preferred).
