About Virtasant

Virtasant is a global technology services company with a network of over 4,000 technology professionals across 130+ countries. We specialize in cloud architecture, infrastructure, migration, and optimization, helping enterprises scale efficiently while maintaining cost control.

Our clients range from Fortune 500 companies to fast-growing startups, relying on us to build high-performance infrastructure, optimize cloud environments, and enable continuous delivery at scale.

About the role

Using a combination of IoT tracking devices and bleeding-edge software solutions, our client transforms with ease outdated processes into lean digital workflows, allowing their customers to interact digitally with their physical equipment, while at the same time, they collect data, derive insights, and improve the efficiency of their operations. Their backend ingests telemetry from physical devices, and ties together the integrations that make it all work.

For our client, we're looking for an experienced Senior Backend Engineer with at least 5 years of relevant experience in software development to own significant projects end-to-end, from scoping through production.

You will play a critical role in building the technical foundation and implementing cutting-edge software technologies that transform existing processes into digital workflows. You will be responsible for designing and building cloud-based applications to improve businesses’ ability to schedule, maintain, and deploy complex equipment configurations. As the team’s technical lead, you will help distill technical ideas into an action engineering roadmap. You will act as a mentor and coach for your team. You must have deep experience with microservice architectures, building highly performant and well-tested code. Your expertise will help our client create an intuitive application where customers can digitally interact with their physical equipment while collecting data, deriving insights, and improving the efficiency of operations.

What You’ll Do

Design and build backend services and APIs in Node/TypeScript, Supabase, and Deno.

•

Work across PostgreSQL and our client's device telemetry data, plus the pipelines that move data between systems.

•

Build and maintain integrations with third-party services and our client's connected devices.

•

Own projects from scoping to launch: define milestones, keep work visible, and ship reliably.

•

Experience operating your own services in production: monitoring, alerting, and observability tooling, and an instinct for designing things to be observable and to fail safely.

•

Comfort shipping behind feature flags and rolling changes out incrementally.

•

A security-conscious approach to code and dependencies.

•

Hands-on experience working with AI coding agents (Cursor, Claude Code, or similar) as part of your daily workflow.

•

A track record of owning projects independently and working through hard problems with little direction.

•

Clear communication and a habit of surfacing issues early.

Nice to haves
