Description

A founder-led engineering company building custom data-extraction solutions is hiring a Middle Backend Engineer. The role focuses primarily on proxy infrastructure and distributed backend systems that handle large volumes of network traffic, route connections and stay reliable under load. You own real pieces end to end: backend services, networking components, traffic routing, connection handling and service communication. The team is a compact senior group with no management layers, working fully remotely and async-first.

Responsibilities

Developing and maintaining backend services for proxy infrastructure
Building efficient and reliable distributed microservice-based systems
Working with networking components, proxy protocols, traffic routing, connection handling and service communication
Investigating performance, reliability, scalability and networking issues
Designing and optimizing services processing large volumes of traffic and operational data
Working with databases, queues, caches and analytics infrastructure
Participating in architecture decisions and improving existing infrastructure and services
Implementing features, fixes and integrations across related backend systems

Requirements

Strong commercial development experience with Go
Good understanding of computer networking and how proxy systems work
Understanding of protocols commonly used in proxy infrastructure and the networking concepts behind them
Experience designing and implementing distributed microservice-based systems
Good understanding of scalability, concurrency, performance, fault tolerance and service reliability
Experience working with production systems and debugging distributed or networking-related issues
Comfortable working with databases, queues, caches and other infrastructure components
Willingness to debug code you did not write and networking you did not configure in production with incomplete information
Proactive approach: come with a concrete fix and trade-offs instead of a status update
Good spoken English sufficient to discuss a design, explain a system or walk through an incident on a call

Conditions

Full-time employment via a B2B contract
Fully remote work with flexible hours and async-first communication, with reasonable overlap with the team
Paid AI tooling, including Claude Code
Genuinely hard technical problems and infrastructure operating at meaningful scale
Short path from a problem to the person who can make the decision, with no bureaucracy between you and shipping
