Java, Full Stack Developer (React)

Net2Source Inc. is one of the fastest growing diversities certified global workforce solutions companies with an unprecedented YoY growth of over 100% for the last 6 years working with Fortune 1000/Global 2000 across 34 countries and 5 continents including North America, South America, Europe, Asia, Australia, and the Middle East.

About the Role:

• Location – London, UK
• Mode of Work – Hybrid (3 Days Per Week)
• Type of Hiring – Permanent / Fixed Term Employment (FTE- 12+ Months)

Technical Experience:

• Experience in any of the following strengthens a candidate’s profile (none are individually mandatory beyond Java and TDD):
• Messaging: Kafka, Solace, TIBCO EMS
• Data: SQL Server, MongoDB, S3 object store
• Observability: Open Telemetry, ELK stack, Grafana
• Secrets Management: Hashi Corp Vault, CyberArk
• Frontend: Messaging, RealTime Data, WebSocket API
• Cloud Infrastructure Build Tools: Vite, Webpack
• CICD: Jenkins, Harness
• Hosting Platforms: Kubernetes, Docker
• Secrets Security: Token based Auth

Domain Experience:

• Candidates must have hands-on experience working in or alongside a capital markets trading or post trade environment.
• Crucially we seek engineers who are proactive in developing deep domain knowledge themselves rather than solely relying on Business Analysts for this expertise.
• The following are indicators of the required depth (not an exhaustive list):
• In-depth understanding of the trade lifecycle including Trade Booking and Position Management principles.
• Practical experience with post trade operations such as Cashflow Calculation, Settlement, Wires, Client Reporting, and Accounting principles.
• Familiarity with corporate actions, regulatory reporting, and integrating with risk valuation systems in an equities context.
• Understanding of Prime Brokerage, Synthetic Swap, or Cash Equity operational flows is a significant advantage.
• Exposure to regulatory reporting obligations in a financial context e.g., 871m, EMIR, MiFID is advantageous.

Requirement:

• We are looking for engineers who combine deep technical craft with genuine capital markets domain knowledge. The two are equally important; candidates who have one without the other are unlikely to be effective in this environment.
• Test-driven Development is non-negotiable. Engineers must be practitioners of TDD, not just advocates, and are expected to own the quality of their deliverables end-to-end rather than outsourcing it to a separate QA group.
• We expect candidates to demonstrate this through their approach to design, not just their ability to write tests after the fact. This will be assessed at interview.
• Event driven architecture: practical experience designing and building systems on message passing and event sourcing patterns including failure handling, ordering guarantees, and replay semantics.
• Agile delivery: strong preference for engineers who have worked in genuine iterative delivery environments with short feedback loops, not waterfall projects labelled as agile. This includes a focus on Continuous Integration Delivery using techniques such as trunk-based development and achieving frequent 1 per week production releases during regular business hours without any service interruption.
