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

- 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.
