Senior Software Engineer

Senior Software Engineer (Systems & Automation)

London, Hybrid, Permanent

We are partnering with a high-growth technology firm in London to find a Senior Software Engineer who excels at the intersection of product engineering and operational efficiency. This is a role for an engineer who is naturally bothered by manual bottlenecks and has the drive to automate them away.

Our client is looking for a "force multiplier", someone who spends their time both shipping core product features and refining the internal engines that allow the entire engineering org to move faster.

The Role

This is not a siloed DevOps or Infrastructure role. You will be a core contributor to the application codebase while taking primary ownership of the workflows, tooling, and pipelines that support it.

• Workflow Optimization: Identify and resolve friction in the developer experience, from reducing build times to refining CI/CD feedback loops.
• Internal Tooling: Design and build bespoke automation, operational dashboards, and scripts that eliminate repetitive manual tasks across the business.
• Cross-Boundary Integration: Solve complex problems that span multiple systems, including data onboarding pipelines and API integrations.
• Product Delivery: Contribute directly to the core product, shipping high-quality features while ensuring the underlying systems remain robust.
• Technical Initiative: Act as a self-starter who notices systemic inefficiencies and independently proposes and implements technical solutions.

Technical Focus

You will work across various layers of the stack, moving fluidly between application logic and the systems that deliver it.

• Environment: High-scale SaaS platforms with a focus on automation and reliability.
• Tooling: Expertise in modern CI/CD architectures, automated testing frameworks, and internal tool development.
• Application Code: Proficiency in building and maintaining production-grade product features.
• Data & Pipelines: Experience building ingestion workflows and connecting disparate internal data sources.
• Stack Versatility: You are highly proficient in Python (FastAPI) and TypeScript (React/Next.js), with a solid grasp of SQL and GCP.

The Profile

• The Practical Automator: You have a track record of saying "this process is slowing us down" and then building the tool to fix it.
• Full-Stack Mentality: You are comfortable working in application code, data pipelines, and deployment systems.
• Product-Minded: You enjoy building features for end-users, but you care deeply about the engineering discipline required to ship them.
• Pragmatic Ownership: You avoid abstract optimization, focusing instead on solving real, measurable operational friction.
