In this role you'll • Design, build, and own production LLM agent systems end-to-end - deciding how the agent thinks, what it's allowed to do, and how it fails safely • Work on our real-time voice agent, where the hard problems are conversational: interruptions, mid-sentence tool calls, and keeping response times imperceptibly fast • Shape the next generation of our knowledge base - how the agent's knowledge is structured, curated, and served, so answers stay grounded as coverage grows • Ship changes as controlled experiments, measure them against thousands of replayed real conversations on our in-house eval platform, and graduate winners into production • Track cost per conversation across millions of LLM calls and find the wins that cut spend without cutting quality • Own what the model knows and says - the customer context it sees, the limits on what it may reveal, and the guardrails against confident nonsense • Build and operate scalable backend services in TypeScript/Node on Kubernetes/AWS with deep observability - if you ship it, you own it What you'll need • 6+ years building production-grade backend systems that real users depend on • Hands-on experience shipping LLM-powered features to production, including honest reckoning with non-determinism, hallucination, and cost • An evaluation mindset - you don't call a change "better" without a measurement, and you're comfortable with the statistics that back that claim • A track record of debugging distributed systems in production, and the discipline to find root cause across service boundaries • Fluency with agentic coding tools like Claude Code or Cursor, including the habit of treating AI-generated code with a senior reviewer's skepticism • The ability to pull your own numbers, design your own experiments, and measure your own impact • Ready to work in an office environment most days of the week

We're looking for a Backend Engineer to help build and scale the Machine Learning Platform that powers how Lemonade uses AI across the business. You'll be part of the ML Platform team, designing the infrastructure that lets our data scientists move faster, ship smarter, and operate with confidence in production. We believe three things matter for every role at Lemonade: drive to push through challenges, efficiency that keeps standards high while moving fast, and adaptability that lets you pivot with data and AI insights. These aren't buzzwords, they're how we actually work. Our AI-first approach isn't just a tagline either. We're building the future of insurance with AI at the center, and we need people who are genuinely excited to learn and grow alongside these tools. In this role you'll • Design and build the foundational ML platform and AI agents to accelerate data science model delivery across all business units • Architect cloud-native microservices running on Kubernetes, using infrastructure-as-code to automate model deployment and management • Own the end-to-end ML lifecycle, covering training, testing, deployment, and real-time monitoring • Evaluate and choose the right tools and technologies based on workload demands and performance requirements • Collaborate with engineering, data science, and product teams to keep ML projects aligned with business goals • Identify and fix reliability, scalability, and performance gaps before they become problems What you'll need • 3+ years of software engineering experience, with a strong record of delivering high-scale, production-grade systems • Strong proficiency in Python • Hands-on experience with relational and NoSQL databases, and at least one major cloud platform (AWS, Azure, or GCP) • Experience with training, testing, deploying, and monitoring real-time or near real-time ML models in production • Fluent with AI-powered development tools like Cursor and Claude Code, and genuinely curious about what's next in GenAI, LLMs, and AI agents • Familiarity with AI concepts like RAG, embeddings, mixture-of-experts, prompt crafting, and LLM context engineering - an advantage • Sharp problem-solving instincts and the ability to move fast without cutting corners • Bachelor's or Master's degree in Computer Science, Engineering, Statistics, or a related field • Ready to work in an office environment most days of the week

Description Quantum Machines is a global leader in control systems for quantum computing, scaling from individual qubits to arrays of thousands. We're looking for a hands-on Tech Lead to drive the technical direction of our core backend layer and lead the engineers building it. The systems you'll own handle bursty, high-throughput workloads: thousands of requests per second, strict latency requirements, distributed coordination, hard concurrency problems. You'll shape the architecture, review the designs, and still write the code. What Makes This Role Different Our backend team is the orchestration layer between: • Hardware control systems (C++) • Client-exposed SDK (Python) • Reporting and management system (Go) • Business logic (Java/Kotlin + Spring) As Tech Lead, you're the technical anchor of that layer. When teams disagree on where a boundary belongs, you drive the decision. When a design has a flaw nobody's spotted, you catch it. When the hardest problem lands, you're close enough to the code to pick it up yourself. Requirements Requirements • 8+ years building backend systems in Java/Kotlin, including experience leading the technical work of a team • You still write code, and you're good at it - this is not a management-only role • Deep concurrency expertise: race conditions, lock ordering, async patterns - and you can teach others to reason about them • Architecture at system scale: throughput, distributed coordination, performance trade-offs • Design review leadership: you can take apart a design constructively and propose one that will hold • A track record of mentoring engineers who got better because of you • You treat code quality as a system property, building the standards and culture that sustain it Strong Plus • Spring experience • gRPC-based communication • Python programming • Experience in polyglot environments • AI coding agent experience, with opinions on how a team should use them well • Experience with real-time, low-latency, or hardware-adjacent systems You'll Thrive Here If You • Lead through reasoning, not title • Ask questions when requirements are unclear, rather than guessing • Know when to insist on "right" vs. "good enough to ship" • Give direct, kind feedback • Communicate clearly, including to non-backend audiences
