Job description

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.
