Senior Backend Software Engineer (Infrastructure)

About the role

Your Role at Nutrient...

We’re looking for a backend engineer passionate about building robust and scalable systems, excited about working with modern cloud technologies and distributed systems to power our Document Engine and SaaS products.

You find satisfaction in architecting high-performance solutions, optimising system reliability, caring for the cloud infrastructure our products run on, and creating efficient backend services that handle complex document processing workflows at scale. You work in an AI-native way: you hand research and implementation work to agents, review their output critically, and build tooling that makes you and the team faster.

What you'll do

What You'll Work On...

• Execute on the design and implementation of high-performance Elixir/Phoenix-based systems such as Nutrient's Document Engine and Web Services API
• Design and build declarative infrastructure, robust, scalable and easy to observe and maintain (we are currently using Terraform, Terramate and FluxCD on Kubernetes, with Helm charts powering both our managed cloud and customer self-hosted deployments)
• Operate and evolve our managed cloud platform: cluster lifecycle and upgrades, GitOps workflows, observability, and database operations, keeping it reliable, secure, and costefficient
• Share ownership for architecture, tools and services, contribute to product development and customer success
• Collaborate closely with a small, remote-first engineering team to ship features, debug hard problems, and continuously improve reliability
• Build systems and workflows that use AI to speed up our work, from agent-driven investigation of performance issues to automating repetitive engineering tasks
• Meet in person with the team periodically to align and reflect

What we're looking for

What You'll Bring...

• Experience in backend services and distributed systems
• A track record running production workloads on Kubernetes and public cloud (we use AWS), ideally with infrastructure-as-code and GitOps practices
• Strong coding skills: Elixir experience isn't required, we'll help you learn
• You work AI-native: agents are part of how you research, investigate and ship code, and you stay fully accountable for what goes out
• A pragmatic approach to code: you appreciate clean architecture but know when good enough is the right call
• A culture of direct feedback: you speak up when something isn't right and take feedback just as well

Nice to have
