Senior Backend Engineer

About Volt

==============

At Volt Labs, we're building the infrastructure layer behind modern business messaging. Our platform helps companies navigate messaging compliance, onboarding, deliverability, routing, and operational complexity across carriers and providers.

We are a remote-first, high-ownership team operating in a fast-moving growth environment. We care deeply about builder mentality, operational excellence, speed with accountability, and creating systems that scale.

We are looking for engineers who want to help define the future of Messaging Ops while using AI as a core part of how they architect, build, troubleshoot, and scale systems.

Role Overview

=================

We are hiring a Senior Back End Engineer to help architect and scale the core infrastructure powering Volt's messaging platform.

This role is focused on building reliable, high-throughput systems that support real-time messaging operations, onboarding workflows, compliance automation, routing intelligence, and operational visibility across providers and carriers.

You will work closely with Engineering leadership, Product, Customer Operations, and Infrastructure teams to improve scalability, reliability, observability, automation, and platform performance.

This is not a narrow feature-delivery role. We are looking for a senior-level builder who can think architecturally, operate independently, and contribute to long-term platform direction while still moving quickly in a startup environment.

Equally important: this is a team role. Our engineering group is small, tight-knit, and genuinely collaborative. We cover for each other, give candid feedback without ego, and take real pride in raising the collective quality of the work. We're looking for someone who strengthens that culture, not someone who operates on an island.

What You'll Do

==================

• Design, build, and maintain scalable back-end systems and APIs
• Improve platform reliability,...
