Senior Software Engineer, Applied AI About Syllo Syllo is on a mission to transform litigation. Our product is a unified litigation platform that enables lawyers and paralegals to safely harness the power of language models and agentic AI throughout the litigation life cycle. Since going to market, we have gained a diverse group of enterprise customers, including some of the biggest law firms and corporations in the country, and we are quickly expanding. By reducing the expense of litigation industry-wide, we aim to improve access to high-quality representation and promote the alignment of legal outcomes with merit. About the Role We are seeking a skilled and fast-moving Applied AI Engineer to join our team. This role is focused on the practical application of AI, specifically leveraging Large Language Models (LLMs), to build robust, scalable, and impactful user-facing features. This is an engineering-centric role. You will be an expert at building and integrating production systems, not primarily a research scientist. Responsibilities Design and build high-performance, production-level AI-powered features and services, with a focus on reliability and scalability. Develop robust engineering solutions to mitigate the inherent unreliability of LLMs. This includes implementing effective guardrails, validation pipelines, error handling, caching, and failover/fallback mechanisms to ensure a high-quality user experience even when the model misbehaves. Design long-running batch processing that is idempotent, resumable, and resilient to individual item failures. Focus on optimizing latency, throughput, and cost efficiency for all AI-powered services. Serve as an engineering expert in integrating models and data feeds with existing business logic and APIs. Define and implement evaluation for AI feature output quality, not only system correctness. Implement rigorous testing strategies, including unit, integration, and performance testing, to ensure the robus

ABOUT THE TEAM The Integrated Workflows team exists to expand Mural's value by embedding it seamlessly into the essential business workflows our customers already live in. We connect Mural to the tools that teams rely on every day, from the systems of record where work gets tracked to the places conversations happen and the surfaces content moves through. That is what integrations unlock, and it is the most interesting thing about this team. When Mural can reach the work happening everywhere else, a canvas stops being a snapshot of one meeting and becomes a live surface for how a team operates: real context pulled in, real decisions pushed back out, nobody retyping a status update or hunting for the current version. A workshop stops ending at the wall of sticky notes and starts ending in tracked, owned, moving work. That is when collaboration gets genuinely effective, and building toward it is the point of everything we do. Underneath all of that, we build the integration platform: the shared frameworks, services, and patterns that let any team at Mural ship a connected experience without starting from scratch. Our mission: to make Mural a natural part of daily work. We measure success by how indispensable Mural becomes inside real customer workflows, not by the number of integrations we ship. YOUR MISSION As a Senior Software Engineer on the Integrated Workflows team, you'll own significant parts of how Mural connects to the outside world. You'll design and build integrations that are reliable, secure, and genuinely used, and you'll turn one-off connector work into integration platform capabilities the rest of the company can build on. This role sits at the intersection of product and platform. You'll work directly against third-party APIs and SDKs with all the ambiguity that entails: shifting contracts, rate limits, auth models, partner review processes. At the same time you'll keep our own abstractions clean and our public API stable for the developers who depend
