Back End Developer

About Moterra

Moterra helps regulated enterprises run Claude inside their own AWS or Azure environment, so customer data never reaches Anthropic’s training pipelines. We’re an official Anthropic partner, based in Borehamwood, UK.

We build two products: Private Claude by Moterra, a private deployment of Claude Cowork inside a customer’s own cloud tenant, and Moterra AI Bridge, the governance and integration layer that connects Claude to a customer’s existing tools such as SharePoint, Salesforce, Slack and SQL databases without needing new SSO or logins.

Our customers are mostly banks, insurers and other regulated organisations that need GDPR and DORA-defensible AI without vendor lock-in. Clients include Vodafone and Lietuvos Bankas, among others.

The role

We’re hiring a mid-level Backend Developer to help build and scale the infrastructure behind Private Claude and AI Bridge. You’ll work closely with our CTO and the rest of the engineering team on the systems that let enterprise customers deploy and govern Claude securely inside their own cloud.

This is a fully remote role, open to candidates based anywhere in the UK.

What you’ll do

• Build and maintain backend services that power secure Claude deployments in customer AWS and Azure environments
• Develop integrations with enterprise systems such as SharePoint, Microsoft 365, Outlook, Salesforce, Slack and SQL databases
• Work on the plugin management and governance features inside Moterra AI Bridge
• Build with security and compliance in mind from the start, given our ISO 27001, ISO 42001, SOC 2 and GDPR/DORA requirements
• Work with the CTO and wider team on architecture decisions
• Support customer deployments and troubleshoot issues in production

What we’re looking for

• 3-5 years of backend development experience, ideally with cloud-native applications
• Hands-on experience with AWS or Azure (Bedrock or AI Foundry a plus)
• Strong skills in a backend language such as Python, Node.js or Go
• Experience with SQL databases and API design
• Understanding of security fundamentals: encryption, key management, access control
• Comfortable working in a small, fast-moving team where you’ll own things end to end
• Based in the UK

Nice to have

• Experience integrating with enterprise tools like SharePoint, Microsoft Teams, Salesforce or Jira
• Familiarity with AI/LLM deployment, or Claude specifically
• Experience working with regulated industries such as financial services or insurance
• Knowledge of compliance frameworks like ISO 27001, SOC 2 or GDPR/DORA

What we offer

• Competitive salary, dependent on experience
• Fully remote, UK-based role
• Direct access to the CTO and founding team, no layers of process to get through
• The chance to shape backend architecture at an early-stage, fast-growing company
• Real, high-stakes work for enterprise and regulated clients
