Backend Engineer

We’re hiring for a fast-growing, venture-backed  security software company building a modern platform used by security teams. This is a hands-on backend role in a high-ownership environment where you’ll move fast, own core services, and build reliable systems that power security workflows at scale.

Important: for this search, we’re only prioritising candidates who have (1) prior startup experience and (2) prior security software product experience .

Must-haves (hard requirements)

Domain + environment

• Startup experience: you’ve shipped and operated production systems in a startup / high-growth environment (ambiguity, pace, ownership)
• Security software product experience: you’ve built or maintained a  security product (e.g., compliance automation/GRC, AppSec tooling, IAM, cloud security, vulnerability management, audit/evidence workflows, security operations tooling) as part of the core product

Technical

• Go (Golang): commercial/production backend services (not “exposure”)
• REST APIs: design + implementation of backend services/APIs
• PostgreSQL: schema design + query optimisation (high-volume data)
• 3rd‑party API integrations: building reliable integration/orchestration layers across internal + external systems
• Production observability: metrics and distributed tracing and/or structured logging (something concrete you’ve implemented/operated)
• SaaS backend/platform experience: architecting/building/operating a production SaaS backend
• Security best practices: authn/authz, secure service-to-service comms, and secure-by-default backend patterns

What you’ll do

• Build and maintain backend services and APIs in Go
• Design and optimise PostgreSQL schemas and queries for high-volume data
• Build reliable integration layers across internal services and third-party systems
• Implement observability across services (metrics, tracing, logging)
• Apply security best practices across the backend
• Collaborate with other engineers to improve developer experience and overall platform reliability

Nice-to-haves

• gRPC (or similar)
• Workflow engines / queue-based job orchestration
• Deeper information security domain experience
• TypeScript exposure (helpful when working closely with frontend/fullstack teams)
