Senior Software Engineer

The Senior Software Engineer will be a core member of the engineering team within the Knowledge & Innovation (K&I) department, responsible for designing, building, and operating the software systems that power the Firm's legal technology and AI initiatives. This role combines strong full-stack development skills with a focus on infrastructure, reliability, and the foundational systems that enable the team to ship and maintain production-grade tools at scale. This role will work across the full stack — building custom applications for attorneys and Professional Staff, establishing the engineering infrastructure that the team relies on (CI/CD, deployment pipelines, observability), and contributing to the design and implementation of AI-powered solutions. The Senior Software Engineer will collaborate closely with the Director of Engineering, data scientists, knowledge management professionals, and practice solutions teams to deliver tools that make a measurable difference in how the Firm operates. This is a hands-on, high-autonomy role on a small team where every engineer has significant ownership over the systems they build. **JOB DUTIES & RESPONSIBILITIES:** **Software Development & Architecture** - Design, develop, and maintain custom software solutions supporting Knowledge & Innovation initiatives, including AI-powered tools, internal platforms, and integrations with existing Firm systems. - Contribute to architectural decisions in partnership with the Director of Engineering, bringing practical perspective on tradeoffs between speed, reliability, and maintainability. - Build and extend integrations across SaaS platforms, internal systems, data sources, and AI/LLM services used in legal workflows. - Develop frontend experiences that are polished, consistent, and designed with care — including establishing and maintaining component libraries and design system foundations as the team's product surface grows. **Infrastructure, Reliability & Observability** - Own and evolve the team's engineering infrastructure: CI/CD pipelines, deployment automation, infrastructure-as-code, and development environment tooling. - Establish observability practices — monitoring, logging, alerting — so the team has confidence in the health and behavior of production systems. - Partner with IT to navigate the Firm's infrastructure environment, coordinating on security protocols, cloud resources, and deployment targets. - Ensure systems are reliable, secure, and aligned with Firmwide technology standards. **AI & Legal Technology Solutions** - Contribute to the development of AI-powered tools — including retrieval-augmented systems, document analysis platforms, search tools, and workflow automation — working alongside product, data scientists, and the broader K&I team. - Help translate complex legal and business requirements into practical, well-engineered software, collaborating with attorneys, knowledge management professionals, and practice solutions managers. - Support adoption and iteration by interfacing directly with legal staff as needed — demoing tools, gathering feedback, and helping users get value from what the team builds. **Collaboration & Craft** - Evaluate and prototype new tools, frameworks, and approaches that could improve how the team builds — bring experiments that work to the rest of the team. - Help establish the engineering culture of a new function — contribute to decisions about how the team works, not just what it builds. **EDUCATION:** - Bachelor's degree in Computer Science or related working experience. **SKILLS & EXPERIENCE:** **Required** - 7+ years of experience in software engineering, with demonstrated progression in scope and responsibility. - Strong full-stack skills across JavaScript/TypeScript, React, Node.js, and Python. - Experience with cloud infrastructure (AWS and/or Azure), infrastructure-as-code (Terraform/Bicep), and CI/CD pipelines (GitHub Actions or equivalent). - Practical experience with AI/LLM integr…
