Senior Software Engineer – Securities Lending Platform
London | Permanent | Up to £120,000 | Hybrid
We are recruiting a Senior Software Engineer to help build a new real-time, event-driven securities lending platform within a global financial-markets business.
This is a senior hands-on engineering role combining Java/Python development, platform architecture, and external market-data integration, with direct exposure to traders and operations.
The platform is being built around two key objectives:
- Workflow automation – streamlining reconciliation, risk management, and reporting processes
- Front-to-back integration – bringing the full trading-to-settlement lifecycle into a single platform
This is an opportunity to join at an early stage and have genuine influence over both the technology and the engineering standards used to build it.
What you'll be doing
- Designing and developing Java server-side and UI components
- Building Python ETL and data-processing pipelines
- Developing integrations with external vendors, market-data providers, and financial systems
- Working with real-time and reference market data, including Bloomberg-related integrations
- Building event-driven workflows using technologies such as Kafka
- Working directly with traders and operations teams to turn business requirements into production solutions
- Owning the design and delivery of technical and process workflows
- Contributing to architecture decisions and the strategic direction of the platform
- Establishing engineering standards and development best practice
- Reviewing code and mentoring more junior engineers
- Representing the platform with internal stakeholders and external technology vendors
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Technology
- Java
- Python
- AWS
- Linux
- PostgreSQL
- Kafka
- Git
What we're looking for
- Typically 7+ years' software engineering experience
- Strong commercial experience with Java and/or Python, with Java particularly desirable
- Strong understanding of software engineering and application architecture
- Practical experience working with relational databases and SQL
- Comfortable working in Linux environments
- Experience integrating applications with external APIs, vendors, or data providers
- Experience contributing to or leading architecture discussions
- Ability to communicate effectively with both technical and non-technical stakeholders
- Experience mentoring engineers and helping establish engineering best practice
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Particularly useful experience
- Any experience within financial markets would be valuable, particularly:
- Securities lending
- Repo
- Delta-1
- Derivatives
- Prime brokerage
- Trading platforms
- Bloomberg or market-data integrations
However, securities-lending experience is not essential if you are a strong engineer coming from a credible financial-services environment.
Why join?
This is not a maintenance role on a mature legacy platform. You will be joining a growing engineering team building a new platform from the ground up, with the opportunity to influence its architecture, technology, and ways of working.
Benefits include:
- Salary up to £120,000
- 25 days' holiday
- Private health insurance
- Relaxed dress code
- Collaborative, engineering-led environment
- London-based role with flexibility for one day working from home per week following probation
