Our platform serves over 1.5 million workers and 375,000 workplaces across 100+ countries. We are backed by top global investors and recently achieved Unicorn status.\r\nAt Deputy, we're improving the world of work, one shift at a time, for 80% of the world's workforce: hourly workers. These are the dedicated employees who keep our world running – from baristas to nurses, cleaners to delivery drivers, florists to factory workers. Despite their vital role in society, most workplace technology has focused on those workers who sit behind a desk, but at Deputy, we transform the frontline. When businesses use Deputy, their workplaces thrive – the business is more profitable, compliant, and productive, while the workers are more engaged and happier at work.\r\nWe're becoming an AI-native company, a commitment that means you'll be empowered (and expected) to use AI tools and thinking in your day-to-day work. You'll have the training, support, and freedom to use AI responsibly and creatively to spark ideas, solve problems faster, and unlock new ways of working.\r\nIf you're passionate about creating solutions that put people first and helping businesses and their teams thrive, join us at Deputy and make an impact where it matters most!\r\nThe Role\r\nAs a backend Software Engineer - Performance, you are a senior individual contributor responsible for owning and driving the performance, scalability, and cost efficiency of Deputy's core Workforce Management platform. This role is highly specialized and hands-on. You will work across core Workforce Management domains—Scheduling, Timesheets, Leave, and Compliance—identifying performance bottlenecks, legacy constraints, and architectural inefficiencies, then leading initiatives end-to-end to address them. You will operate with a high degree of autonomy, forming and leading performance-focused initiatives that often run without direct product direction. You will define the problem, shape the technical approach, break work into deliverable milestones, and drive execution through collaboration and influence rather than line management. Your work will directly impact mid-market and enterprise customers operating at scale, supporting high-volume workloads across multiple regions and time zones, and ensuring the platform continues to perform reliably as data volumes, customer complexity, and usage grow.\r\nResponsibilities\r\nPlatform Performance Ownership\r\nOwn and continuously improve the performance posture of the Workforce Management platform across core domains, with a focus on API latency, page load times, and infrastructure cost efficiency.\r\nProactively identify performance risks and bottlenecks across legacy and modern systems, addressing issues before they impact customers.\r\nLead initiatives to modernise and simplify legacy customisations and workflows that negatively impact performance, reliability, or operational cost.\r\nHands-on Technical Leadership\r\nDesign, implement, and deliver performance-focused improvements across backend services, APIs, data stores, and search infrastructure.\r\nPerform deep analysis of SQL queries, database access patterns, and data models, driving query optimisation, indexing strategies, and data access improvements.\r\nDesign and implement effective caching strategies (application-level, data-store, and API-level), balancing performance gains with correctness and consistency.\r\nWork extensively with OpenSearch at scale, optimising indexing, query performance, ingestion pipelines, and cost efficiency for systems ingesting millions of new records each week.\r\nLegacy Modernisation & Migration\r\nWork hands-on with legacy codebases, including long-lived PHP systems, identifying opportunities to improve performance, reliability, and maintainability.\r\nLead and contribute to incremental migration strategies that transition performance-critical paths from legacy systems to modern solutions (e.g. Go-based services), without disrupting customer workflows.\r\nBalance short-term performance improvements with longer-term platform modernisation, ensuring changes are safe, observable, and reversible.\r\nMulti-Tenant & Enterprise Scale\r\nDesign and implement performance solutions that operate effectively in multi-tenant environments, maintaining isolation, fairness, and predictability across customers.\r\nOptimise systems that handle high concurrency, large data volumes, and enterprise usage patterns across multiple regions and time zones.\r\nInitiative Leadership & Influence\r\nDefine and own performance initiatives end-to-end, from problem discovery and technical design through to delivery and validation.\r\nBreak complex problems into clear milestones and delegated tasks, collaborating with engineers across squads to drive outcomes.\r\nSet and uplift platform performance standards, tooling, and ways of working in partnership with Infrastructure, Quality, and Product Engineering teams.\r\nMentor and guide other engineers in performance-oriented thinking, debugging techniques, and system design, leading by example through hands-on contribution.\r\nSkills & Experience\r\nCore Experience\r\n6+ years of professional software development experience, including operating production systems at scale.\r\nHands-on experience across multiple Workforce Management domains, such as Scheduling, Rostering, Timesheets, Leave, and Compliance, will be highly regarded.\r\nProduct and domain understanding of Workforce Management, including the operational and compliance complexity faced by mid-market and enterprise customers, will be highly regarded.\r\nPerformance, Data & Systems\r\nProven experience leading and delivering performance optimisation initiatives across complex systems.\r\nStrong expertise in SQL query optimisation, including execution plans, indexing strategies, and tuning for high-volume workloads.\r\nExtensive experience designing and operating caching strategies, including cache invalidation and consistency trade-offs.\r\nHands-on experience with OpenSearch at scale, including index design, query optimisation, ingestion pipelines, and cost/performance trade-offs.\r\nArchitecture & Modernisation\r\nProven experience working with legacy systems and modern platforms, including planning and executing migrations from legacy architectures to modern solutions.\r\nExperience evolving performance-critical paths from monolithic or tightly coupled systems into more maintainable, scalable implementations.\r\nStrong backend engineering skills, with experience in PHP and Go highly advantageous.\r\nExperience designing and operating APIs (REST, RPC) and distributed systems using modern cloud infrastructure and tooling.\r\nTechnical Leadership\r\nComfortable operating as a senior individual contributor with broad influence and ownership, without direct reports.\r\nAbility to lead through technical credibility, collaboration, and pragmatic decision-making.\r\nStrong communication skills, able to explain complex performance and architectural trade-offs to both technical and non-technical stakeholders.\r\nA pragmatic problem solver with a strong bias toward measurable improvement, system health, and continuous learning.\r\nEmployee Perks\r\nEnjoy a flexible work policy (with a work-from-home stipend to set you up for success!)\r\nOwn a piece of Deputy via our Employee Share Ownership Plan (ESOP)\r\nTake
