Backend Engineer

Redikru builds products for job seekers, employers, and the crewing industry. We're hiring a mid-level backend engineer to build dependable systems in Golang and Node.js, make sound architectural decisions, and use AI well in everyday work. There's room to grow into a Full-Stack or Forward Deployed Engineer role as the company grows.

What you'll do:

• Build and maintain backend services and REST APIs in Golang and Node.js (TypeScript), including data models, migrations, integrations, and system architecture.
• Work with PostgreSQL, Redis, job queues, background workers, and SSE, and design for transactions, caching, retries, failure handling, and feature-flagged rollouts.
• Write tests (unit and integration against real infrastructure) and documentation.
• Investigate production issues and improve performance, reliability, security, and observability across Docker, Kubernetes/Helm, AWS S3, OpenSearch, and CI/CD.
• Use AI for exploration, planning, coding, testing, and debugging, and review its output before it ships.
• Make small frontend changes when needed and work with product and operations to solve real business problems.

What we're looking for:

• Backend engineering experience building production REST APIs in Golang and Node.js/TypeScript. Deep in one and comfortable in the other is fine.
• Framework experience such as Gin (Go) or NestJS/Express (Node.js).
• Solid PostgreSQL skills: schema design, transactions, indexing, and performance tuning.
• Experience with Redis, async processing, and failure handling.
• Familiarity with Docker, CI/CD, Kubernetes/Helm, cloud infrastructure, and observability.
• Good judgment on system design, testing, and security, plus clear communication.
• Pluses: React, gRPC.
