Backend Engineer (Go)

Job Details

Role Overview

vQsystems is seeking an exceptional Backend Engineer (Go) to architect and build the core systems powering our next-generation intelligent infrastructure platform.

This is not a routine backend role — you’ll be designing highly distributed, performance-sensitive, and secure systems that will form the backbone of mission-critical applications used across multiple domains.

We’re building for the future — where reliability, scalability, and intelligent automation converge. If you thrive on solving complex system-level problems, optimising for scale, and engineering with purpose, this role offers a unique opportunity to shape the foundations of an innovative product ecosystem.

Responsibilities

• Design and implement high-performance backend services using Go (Golang).
• Architect and maintain distributed, fault-tolerant systems with microservices-based infrastructure.
• Build and optimise REST/gRPC APIs for real-time data exchange and cross-service communication.
• Collaborate with frontend, AI/ML, and DevOps teams to ensure seamless integration and system reliability.
• Implement secure data processing pipelines, encryption layers, and authentication systems aligned with modern security standards.
• Lead performance tuning, memory profiling, and concurrency optimisation.
• Contribute to infrastructure-as-code using tools like Terraform and CI/CD pipelines for automated deployment.
• Research and integrate new backend technologies to continually push architectural excellence and system resilience.
• Participate in technical design reviews, code audits, and scalability assessments.

Requirements

• 4+ years of backend development experience, with at least 2+ years using GoLang in production.
• Strong understanding of concurrency, goroutines, and Go memory management.
• Proven experience in building and scaling microservices and event-driven architectures.
• Proficiency with cloud platforms (AWS / GCP / Azure) and container orchestration (Docker, Kubernetes).
• Deep understanding of system design principles, distributed computing, and network protocols.
• Solid experience with PostgreSQL, Redis, or similar databases.
• Familiarity with CI/CD, infrastructure automation, and monitoring tools (Grafana, Prometheus, etc.).
• Strong commitment to code quality, security, and performance.
• Excellent problem-solving skills and ability to work in a fast-paced, high-accountability environment.

Preferred Qualifications:

• Experience with real-time systems, low-latency applications, or cybersecurity-grade architectures.
• Background in AI/ML pipeline integration, data encryption, or multi-tenant SaaS environments.
• Understanding of Zero Trust architecture and secure backend communication models.
• Open-source contributions or experience in building core system components at scale.

Benefits

• Competitive UK salary and equity participation.
• Opportunity to contribute to complex, cutting-edge system architectures.
• Continuous professional growth and R&D involvement.
• Access to advanced tools, cloud infrastructure credits, and mentorship from top-tier engineers.
• Be part of a company shaping the next evolution of secure intelligent systems.
