Position Overview

As a mid‑level Software Engineer at Diligent you’ll take on a hands‑on technical role in building secure, scalable, and high‑performing serverless microservices using Node.js, TypeScript, and React on AWS. You’ll contribute meaningfully to our mission of making governance effortless for our customers, working in a team that owns its services end to end—from architecture and implementation to monitoring and continuous improvement.

This role is ideal for a mid‑level engineer who writes solid code, mentors others, and embraces AI‑powered tools to work smarter and faster. You’ll work side by side on creative challenges, shape architectural discussions, and help scale modern development practices—including responsible use of AI in workflows.

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.

Required Experience / Skills

• 35 years of professional software engineering experience in an agile, fast‑paced environment.
• Familiar with core AI concepts (tokens, context length, embeddings, hallucinations) and 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, 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.
