By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we're reshaping how critical knowledge work gets done for decades to come.This is a rare chance to help build a generational company at a true inflection point. With 700customers in 58countries, strong product-market fit, and world-class investor support, we're scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth personal, professional, and financial is unmatched.Our team is sharp, motivated, and deeply committed to the mission. We move fast, operate with intensity, and take real ownership of the problems we tackle from early thinking to long-term outcomes. We stay close to our customers from leadership to engineers and work together to solve real problems with urgency and care. If you thrive in ambiguity, push for excellence, and want to help shape the future of work alongside others who raise the bar, we invite you to build with us.At Harvey, the future of professional services is being written today and we're just getting started.Role OverviewAs a Backend Platform Engineer at Harvey, you will help build and operate the cohesive backend platform that all our services run on. In this mid-to-senior level role, you'll design and implement shared frameworks and libraries that abstract common concerns, improve developer experience, and raise the baseline for reliability and performance across all teams. Your mission aligns with our platform charter:create a shared foundation that enables product teams to ship reliable, observable, and performant experiences quickly and safely. By centralizing common work, you'll let product engineers focus on shipping features rather than re-inventing the wheel. This is a high-impact role where the code you write and the systems you build will amplify the productivity and quality of engineering across the entire company.If you're excited about building foundational systems, solving cross-cutting technical challenges, and enabling others to move faster with confidence, we'd love to hear from you.What You'll DoDevelop and maintain Harvey's internal backend frameworks and libraries that provide common capabilities (API routing, service lifecycle management, caching and messaging primitives, error handling interfaces, etc.), so product teams don't have to reinvent themCreate and improve APIs, service templates, and versioned interfaces that establish consistent patterns for building new services and featuresIntroduce and champion modern backend architecture patterns like asynchronous I/O (asyncio) and streaming data processing, continually evolving our platform for better performance and scalabilityDesign Harvey-specific abstractions and domain-specific frameworkscovering cross-cutting concerns (e.g., authorization, streaming) and areas like data governance and event processingto provide product engineers with these capabilities out of the box.Embed reliability and observability into the platform by building in tracing, metrics, and automated tests (shift-left), ensuring services built on our foundation are robust and easy to monitorCollaborate with Model Infrastructure team to tackle challenges unique to GenAI-native applications such as supporting high-throughput model inference, managing streaming and long-running API interactions, and designing abstractions for retrieval, context handling, and prompt lifecycleCollaborate with the Developer Experience and Infrastructure teams (who own CI/CD pipelines, build tools, and release infrastructure) to integrate our platform components seamlessly into the deployment and monitoring ecosystemWork closely with product engineering teams to gather feedback, evangelize best practices, and make the paved road approach a reality providing strong defaults and clear documentation so teams can move fast with confidenceWhat You Have7years of software engineering experience (post-BS/MS), including building scalable backend systems or internal developer platformsProficiency in Python (or similar languages) and deep knowledge of backend development fundamentals (APIs, data stores, concurrency, distributed systems)Hands-on experience with web frameworks and service architectures (e.g. Flask/FastAPI, Bounded context services, microservices) and an understanding of designing clean, versioned APIsFamiliarity with caching, messaging, and database technologies (Redis, Kafka, SQL/NoSQL databases, Vector databases, etc.) and how to use them effectively for high performance and reliabilityA track record of writing high-quality, well-tested code and using tools (unit/integration testing, static typing, CI) to catch issues early and ensure reliabilityStrong problem-solving skills and a passion for improving developer experience you enjoy creating tools or frameworks that make other engineers more productiveExcellent collaboration and communication skills, with the ability to work across teams and incorporate feedback.Experience contributing to or maintaining internal libraries/frameworks is a plus.Compensation Range$238,000 - $290,000 USDHarvey is an equal opportunity employer and does not discriminate on the basis of race, gender, sexual orientation, gender identity/expression, national origin, disability, age, genetic information, veteran status, marital status, pregnancy or related condition, or any other basis protected by law.
