Senior Backend Engineer
About The Position
Volt Labs is seeking a Senior Backend Engineer to architect and scale the core infrastructure of their messaging platform. This role focuses on building reliable, high-throughput systems for real-time messaging operations, onboarding, compliance, routing, and operational visibility. The engineer will collaborate with leadership, Product, Customer Operations, and Infrastructure teams to enhance scalability, reliability, observability, automation, and performance. This is a senior-level position requiring architectural thinking, independent operation, and contribution to long-term platform direction within a fast-paced startup environment. The role emphasizes teamwork, collaboration, and a shared commitment to quality within a small, tight-knit engineering group. A key aspect of this role involves leveraging AI tooling to augment development, troubleshooting, and scaling processes, with an expectation for engineers to have transitioned to AI-augmented workflows beyond basic assistance.
Requirements
- Strong experience building and scaling back-end systems in production environments
- Experience designing APIs and distributed systems
- Strong understanding of system performance, scalability, and reliability
- Experience with cloud infrastructure and event-driven architectures
- Strong troubleshooting and systems-thinking mindset
