Senior Staff Engineer

We re looking for a Senior Staff Software Engineer to help evolve one of the most critical platforms at tem

This platform powers complex commercial workflows across forecasting, pricing, optimisation, and deal execution - sitting directly on the path between customer demand and revenue generation

You re work on large-scale backend and platform engineering problems where correctness, reliability, and operational clarity matter deeply. The domain is complex, the stakes are high, and the technical challenges span architecture, scalability, workflow orchestration, data modelling, and developer productivity

This is a hands-on Staff+ role for someone who enjoys building robust systems in ambiguous environments, driving execution across teams, and shaping technical direction through delivery

Responsibilities

• Lead Through Execution: Drive major technical initiatives from design through production, improving scalability, reliability, and correctness across critical systems
• Build Distributed Systems: Design and evolve backend services, APIs, event-driven workflows, and data models that support complex business processes at scale
• Own Critical Platform Infrastructure: Improve the operational foundations of the platform through better observability, testing, deployment safety, and incident reduction
• Solve Complex Workflow Problems: Design systems that handle long-running workflows, asynchronous processing, consistency guarantees, and failure recovery in high-stakes environments
• Work Across Teams: Lead initiatives spanning engineering, product, data, commercial, and machine learning teams - aligning stakeholders and unblocking delivery
• Productionise Machine Learning: Collaborate with ML and data teams to safely integrate forecasting, optimisation, and pricing models into production systems
• Raise Engineering Standards: Mentor senior engineers, influence architectural direction, and improve engineering practices across the organisation
• Design for Scale: Anticipate scaling challenges before they emerge - improving throughput, resilience, and platform evolution as the business grows

Who you are

• Strong Technical Leadership: You ve operated at Staff or Senior Staff level and have led technically complex initiatives with meaningful business impact
• Distributed Systems Expertise: Deep experience designing and operating scalable backend systems, event-driven architectures, APIs, and asynchronous workflows
• Hands-On Engineering Depth: You still enjoy building software directly - writing production code, reviewing designs, debugging systems, and improving architecture
• Modern Backend Experience: Strong experience with technologies such as:

• Python
• AWS (Lambda, API Gateway, DynamoDB)
• Event-driven/serverless architectures
• Distributed systems and workflow orchestration

• Systems Thinking: You re comfortable reasoning about correctness, failure modes, data consistency, scalability, and operational trade-offs in complex systems
• Cross-Functional Influence: You can align technical decisions with product, commercial, and customer outcomes while navigating ambiguity effectively
• Pragmatic Problem Solving: You enjoy untangling difficult technical and organisational problems using first-principles thinking

Desirable

• Experience with high-scale infrastructure or performance-sensitive systems
• Background in platform engineering or internal developer platforms
• Exposure to workflow engines, orchestration systems, or real-time decision systems
• Experience integrating ML models into production environments
• Familiarity with regulated industries such as energy, fintech, or govtech
• Experience evolving systems from startup scale to multi-product platforms
• Knowledge of Kubernetes, Spark, or large-scale data systems
