Senior Principal Software Engineer Java

Senior Principal Software Engineer Java Overview

Anaplan is looking for a senior principal-level software engineer to join its Manchester team and help shape the platform behind its enterprise decision-making product. The company describes itself as a group of innovators building an AI-enhanced scenario planning and analysis platform that helps customers make better decisions faster and stay ahead of competitors. The role sits within the Platform Experience area and focuses on the systems that power API gateways, edge routing, developer enablement, and other core platform capabilities used at very large scale.

What you will do

• Take the lead on architecture, design, and delivery for platform services that support enterprise API gateways, edge routing, and tools that improve developer productivity.
• Build and expand backend systems that process large volumes of traffic, coordinate request handling, maintain strong isolation between tenants, and provide API-first functionality for thousands of tenants and tens of thousands of users.
• Work alongside architects and senior engineers to define technical direction and align implementation patterns for major initiatives such as vanity URL support, JWT authentication flows, and cross-service proxying.
• Help advance deployment and release practices by promoting GitOps-based workflows and supporting container orchestration that is highly available and production-ready.
• Own important platform features from early design through production rollout and ongoing operation, with a focus on observability, intelligent throttling, and solving difficult concurrency problems such as locking and connection starvation.
• Write high-quality code and provide technical leadership in Java and Kotlin, making sure backend microservices integrate smoothly with UI components and that edge proxy and CORS-related challenges are handled correctly.
• Mentor engineers across multiple regions through design feedback, pair programming, and direct technical guidance, helping strengthen the overall engineering culture.

What the team is looking for

• Substantial experience building software in enterprise environments where systems must handle high throughput and scale reliably.
• Strong familiarity with modern AI-assisted engineering approaches, including agentic coding patterns and LLM-supported workflows, and the ability to use these tools to improve platform engineering speed.
• Deep backend expertise in Java and/or Kotlin, plus a strong grasp of how distributed systems work internally.
• Proven experience delivering API-first platforms, API gateways such as Traefik, and edge routing solutions that remain dependable under sustained traffic of 2,000 or more requests per second.
• Hands-on knowledge of Kubernetes, containerized deployments, and sophisticated CI/CD pipelines, along with comfort using GitOps, ArgoCD, and rapid release practices.
• Solid understanding of event-driven systems, real-time data handling, and transaction management in large-scale environments.
• The ability to balance quick experimentation and iteration with long-term code quality and maintainability, with a preference for action and learning over waiting for perfect certainty.
• Excellent communication skills, especially the ability to turn complex ideas into clear RFCs and architecture documents that help distributed teams reach agreement.
• Comfort working across time zones and domains in an asynchronous, collaborative environment.

Nice-to-have experience and personal qualities

• Experience influencing architecture and platform strategy at enterprise scale, including trade-offs across hybrid and cloud-agnostic environments.
• A polyglot approach to technology, choosing the best tool for the problem and being open to working with technologies such as React, Python, or Go when appropriate.
• Curiosity and enthusiasm for learning new technologies and approaches to solve platform enablement and edge routing challenges.
• A genuine interest in mentoring others and helping raise engineering standards without ego.
• Confidence working in distributed teams and contributing effectively through asynchronous collaboration and consensus building.
