It's cutting-edge, high-impact work, and usage is climbing fast.

About the Role:

As a Senior Software Engineer I, you will:

• Contribute to technical decision-making, influencing product direction, cloud infrastructure, and application architecture.
• Design and ship client-facing REST APIs - defining contracts up front, with developer experience and consumer ergonomics treated as first-class concerns.
• Build scalable cloud services that process millions of documents per month, using AI/ML technologies including LLMs.
• Collaborate cross-functionally with engineers, product managers, scientists, and legal experts.
• Mentor more junior engineers and contribute to the team's engineering culture.

About You:

You are a fit for the role of Senior Software Engineer I if your background includes –

Required Skills and Experience:

• Bachelor's degree in computer science, software engineering, or a related field; or equivalent practical experience.
• 4+ years of software development experience, with a strong focus on cloud-native application hosting and maintenance (preferably on Azure; AWS or GCP also valuable).
• Experience designing and building clean, well-documented client-facing REST APIs using an API-first approach - defining contracts (e.g., OpenAPI / Swagger) before implementation, with developer experience and consumer ergonomics treated as first-class concerns.
• Strong proficiency in C# / .NET and SQL, with working knowledge of Angular.
• Hands-on experience with containerization (Docker, Kubernetes), CI/CD pipelines (GitHub Actions), and version control (Git).
• Comprehensive understanding of the entire software development lifecycle, including agile methodologies, testing, monitoring, and incident management.
• Experience providing technical leadership within a development team, including but not limited to: mentoring junior developers, reviewing code, training on new technologies / concepts, and providing input on technical decisions.
• Exceptional communication skills, both written and verbal, with the ability to:
  • Build and maintain strong relationships with stakeholders
  • Contribute positively to long-term team dynamics and health
• Demonstrated ability to solve complex technical problems creatively and effectively.
• Adaptability and eagerness to learn new technologies and methodologies in a rapidly evolving field.
• Hands-on experience with AI-assisted development tools (e.g. Claude Code, Cursor, GitHub Copilot)
• Willingness to participate in the team's on-call rotation.

Preferred Skills and Experience:

• Familiarity with other strongly typed languages (e.g. C++, Java, Go - Rust experience is particularly welcome) is a plus, as is experience with AWS or GCP.
• Experience with AI/ML technologies - especially MLOps (model hosting and deployment), large-volume document processing, NLP, and/or LLM-based applications (RAG, agentic workflows, prompt engineering) - is highly desirable.
• Familiarity with the legal industry is a plus; experience in legal tech is particularly welcome.
