Job Description

Buy-Side Trading Systems Developer (Python/.NET/Angular + Databricks)

NextWave Consulting is hiring a software developer to support a buy-side investment management transformation. This role sits close to front-office trading technology and focuses on building, integrating, and improving systems connected to Charles River, Adroit, and Databricks. You will work with internal technology teams, business users, and external vendors to deliver reliable, scalable solutions in a regulated environment.

What you will do

• Design, build, test, and support components across trading and investment management systems.

• Develop and maintain applications, services, and integrations using Python, .NET, Angular, SQL, APIs, and Databricks.

• Build and optimise data flows, database objects, and reporting logic to improve performance, data quality, and operational visibility.

• Work directly with traders, technology stakeholders, and vendors to turn business requirements into practical technical solutions.

• Investigate production issues, fix defects, and improve resilience across integrated platforms.

• Follow strong engineering practices for coding, testing, documentation, change control, and deployment in a regulated financial environment.

What you need to bring

• Experience as a software engineer or developer in financial services, ideally within asset management, buy-side trading, or capital markets.

• Strong hands-on development skills in Python, .NET, Angular, SQL, and Databricks.

• Practical experience building and supporting integrations using APIs, including REST and WebSockets. SOAP experience is useful but not essential.

• Strong SQL capability, including query writing, optimisation, stored procedures, and schema design.

• Good understanding of trading workflows, market data, and order/execution management concepts. Experience with Charles River or similar OMS platforms is highly valuable.

• Strong problem-solving skills, clear communication, and the ability to work with both technical and non-technical stakeholders.

• Comfort working in an environment where priorities can shift, vendor dependencies exist, and delivery quality matters.

Reality check

• This is more engineering-led than pure integration/support, a blend of greenfield + integration (not just fixing systems).

• You will likely be working across legacy and modern technologies at the same time.

• Domain context matters. Candidates without financial markets or trading systems exposure may find the learning curve steep.
