Job description

At Diligent, we're building the future with people who think boldly and move fast. Whether you're designing systems that leverage large language models or part of a team reimaging workflows with AI, you'll help us unlock entirely new ways of working and thinking. Curiosity is in our DNA, we look for individuals willing to ask the big questions and experiment fearlessly - those who embrace change not as a challenge, but as an opportunity. The future belongs to those who keep learning, and we are building it together. At Diligent, you're not just building the future - you're an agent of positive change, joining a global community on a mission to make an impact.

Key Responsibilities

• Own and deliver well-defined stories independently, with a clear grasp of team architecture, frameworks, and tools.
• Actively contribute to code reviews, testing practices, and maintain service stability.
• Support and guide junior engineers (SE-I), fostering collaboration, knowledge sharing, and constructive feedback.
• Maintain healthy development flow by adhering to Agile processes and driving iterative enhancements.
• Use AI tools to accelerate coding, debugging, testing, research, and code reviews, always validating outputs and applying judgment.
• Understand core LLM concepts (e.g., tokens, context length, hallucinations), recognize safe vs. unsafe use cases, and flag ethical, privacy, or cost concerns.

Qualifications

• 3-5 years of professional software engineering experience in an agile, fast‑paced environment.
• Familiar with core AI concepts (tokens, context length, embeddings, hallucinations), understands high‑level LLM behavior, and recognizes safe vs. unsafe use cases (privacy, security, fairness).
• AI Tooling & Practices: Uses AI to boost productivity (e.g., test scenarios, architecture drafts, research), skilled in prompt engineering (instruction vs. few‑shot), and evaluates AI outputs responsibly (bias, cost, ethics).
• Backend Proficiency: Builds RESTful APIs with Node.js/TypeScript, works with Docker/container workflows, employs Git for version control, and has hands‑on experience with SQL databases (e.g., PostgreSQL).
• Frontend familiarity: Experience using React or Angular for modern web interfaces.
• Cloud & infrastructure basics: Hands‑on with AWS services; familiarity with infrastructure as code (CDK, Terraform) is a plus.
• CI/CD mindset: Experience or interest in CI/CD pipeline setup and exploring AI‑assisted DevOps tooling.
• Collaboration & communication: Comfortable discussing architectural decisions, documenting designs (potentially with AI assistance), and presenting technical ideas clearly.

Benefits & Perks

• Diligent is the AI leader in governance, risk and compliance (GRC) SaaS solutions, helping more than 1 million users and 700,000 board members to clarify risk and elevate governance.
• We care about our people. Diligent offers a flexible work environment, global days of service, comprehensive health benefits, meeting free days, generous time off policy and wellness programs.
• We have teams all over the world. We may be headquartered in New York City, but we have office hubs in Washington D.C., Vancouver, London, Galway, Budapest, Munich, Bengaluru, Singapore, and Sydney.
• Diversity is important to us. Growing, maintaining and promoting a diverse team is a top priority for us. We foster and encourage diversity through our Employee Resource Groups and provide access to resources and education to support the education of our team, facilitate dialogue, and foster understanding.
• Diligent created the modern governance movement. Our world‑changing idea is to empower leaders with the technology, insights and connections they need to drive greater impact and accountability - to lead with purpose.

Location & Work Model

The role will follow a hybrid work model. If you are within a commuting distance to one of our Diligent office locations, you will be expected to work onsite at least 50% of the time. We believe that in‑person engagement helps drive innovation, teamwork, and a strong sense of community.
