Senior Software Engineer

They are seeking an engineer who uses AI as a high-leverage productivity tool while remaining the ultimate authority on architecture, correctness, security, scalability, and operational integrity.

You'll join a high-calibre engineering team building complex, multi-tenant systems where quality, governance, and operational excellence are non-negotiable. The Opportunity

This role is ideal for a deeply technical engineer who enjoys ownership, autonomy, and solving hard infrastructure and systems problems at scale.

You'll own features end-to-end - from initial architecture through to deployment in customer cloud environments - while helping shape engineering standards across the platform.

AI-assisted tooling is embraced as part of the development lifecycle, but always within a governed, human-led engineering culture. Key ResponsibilitiesEnd-to-End Feature Ownership

Take ownership of features from design and implementation through to production deployment. Use AI-assisted tooling to accelerate delivery while ensuring every output meets high standards for maintainability, security, and performance. Engineering Standards & Architecture

Contribute to the evolution of a modern TypeScript platform built on strict engineering principles. Drive consistency and quality across services using technologies including Bun, Elysia, Drizzle ORM, and Postgres. Cloud Deployability & Operational Excellence

Build software designed to run seamlessly inside customer-managed Kubernetes environments. Ensure services are deployable, observable, properly namespaced, and supported by robust automation and operational tooling. Multi-Tenant Data Isolation

Design and implement rigorous tenant isolation controls at schema and application level. Develop comprehensive testing strategies that guarantee customer data separation and platform integrity. Observability & Autonomous Systems

Implement deep observability using OpenTelemetry to ensure all system and agentic behaviours are traceable, explainable, and auditable across distributed environments. Technical Review & Mentorship

Act as a senior technical reviewer and engineering mentor. Help maintain engineering quality across AI-assisted contributions by identifying architectural risks, hallucinated logic, security concerns, and technical debt early. About YouSenior Engineering Mindset

You understand that seniority is about judgement, governance, and long-term thinking. You know where shortcuts create future operational problems - and you have the discipline to prevent them. AI-Leveraged, Not AI-Dependent, You'll work alongside senior engineers who view AI as a force multiplier - not a substitute for engineering excellence. Skills

You actively use GenAI and AI-assisted tooling to improve productivity, but your engineering fundamentals are exceptionally strong. You can independently debug race conditions, optimise SQL queries, interpret Kubernetes manifests, and troubleshoot distributed systems. Deep Technical Expertise

You have recent hands-on experience shipping production-grade TypeScript applications and are comfortable working within highly opinionated, strongly typed codebases.

You can confidently navigate:

• Drizzle ORM migrations
• React Server Components
• Distributed systems patterns
• Backend performance optimisation
• Cloud-native infrastructure

Kubernetes & Multi-Tenant Experience

You've worked on systems where tenant isolation, compliance, and operational reliability were mission-critical. You are comfortable with Kubernetes concepts including ingress, network policies, resource management, and deployment automation. Strong Communicator

You thrive in remote, high-velocity engineering environments and understand the importance of clear written communication. You produce documentation and runbooks that are accessible to both engineers and AI-assisted operational workflows. Technical EnvironmentBackend & Runtime
