Software Engineer - Compliance / Regulatory Reporting

The Compliance/Regulatory Reporting technology team at Millennium builds solutions to meet the firm’s global regulatory and reporting obligations. We use AI-assisted development tools (e.g., Claude Code), cloud-native/serverless architectures on AWS, and modern full-stack technologies (C#, Angular, SQL), with a strong focus on Domain-Driven Design (DDD) and automated testing.

The role is suited to engineers who have delivered real-time, mission-critical systems in high trade volume, distributed and fault-tolerant environments.

Responsibilities

• Design and build scalable, real-time Regulatory/Compliance applications using C#/.NET, Angular, and SQL, leveraging AI-assisted tools to accelerate development and improve quality.
• Model business domains using DDD (bounded contexts, aggregates, entities, value objects, domain services, domain events) with a strong focus on business correctness and ubiquitous language.
• Architect and implement cloud-native/serverless solutions on AWS, including:
• Event-driven services using AWS Lambda and messaging/streaming (Kafka, SQS, SNS).
• Containerized microservices using Docker and Kubernetes (e.g., Amazon EKS).
• Build and maintain Angular front-ends that integrate securely and efficiently with backend APIs and domain services.
• Design and optimize relational data models and SQL queries (SQL Server, Snowflake) for high-volume, low-latency workloads.
• Drive a test-first mindset with strong automated test coverage (unit, integration, contract, and end-to-end) for critical domain workflows and controls.
• Collaborate with global business and Compliance stakeholders to understand requirements, shape domain models, and deliver auditable, production-ready solutions.

Requirements

Core Engineering & Full-Stack Skills

• Practical experience with AI-assisted tools (e.g., Claude Code, GitHub Copilot) for code generation/refactoring, test creation, debugging, and documentation
• Expert-level C#/.NET and strong object-oriented design skills
• Solid experience building Angular applications (components, state, routing, API integration)
• Advanced SQL skills for schema design and complex queries (SQL Server, Snowflake)
• Experience with high-throughput, concurrent/multithreaded systems
• Kafka or similar messaging experience, including using JSON and Avro for data contracts in streaming and messaging
• Strong understanding of unit testing, Dependency Injection, design patterns, concurrency, and SOLID principles
• Experience with Git and GitHub in a collaborative, code-review-driven workflow

Soft Skills & Domain Knowledge

• Excellent analytical and problem-solving abilities.
• Self-starter who thrives in a fast-paced, globally distributed environment.
• Strong written and verbal communication skills with the ability to explain domain models, testing strategies, and architectural decisions to varied audiences.
