We're working with a specialist investment technology firm that is building and scaling the technology behind its investment and trading operations.
This is a great opportunity for a strong backend engineer who wants more than just another feature-development role.
You'll work on systems handling real-time market data, portfolio accounting, risk, performance analytics and trading operations - with data flowing directly from major exchanges and financial data providers.
The engineering team is intentionally small, which means you'll have significant ownership and influence. You'll help design systems, make architecture decisions, write production code, deploy what you build, and see your work used by the investment team every day.
What you will do:
Build backend services supporting portfolio monitoring, accounting, risk and investment operations
Design reliable APIs and internal services using Python
Build data pipelines handling high-volume market and trading data
Integrate with major exchanges and financial data providers through REST and WebSocket APIs
Work with market data at tick-level granularity
Build systems that calculate NAV, returns, risk and performance metrics
Design and evolve PostgreSQL databases for performance and reliability
Improve observability, monitoring, alerting and production reliability
Deploy and operate your own services in AWS
Participate in system design and make architectural decisions — including understanding and explaining the trade-offs
Establish better engineering practices around testing, CI/CD, code reviews and production operations
What you will need:
4+ years of professional backend engineering experience
Strong Python development experience
Strong SQL and PostgreSQL skills
Experience designing and building backend systems that run in production
Experience developing REST APIs
Experience deploying and operating services on AWS
Experience with production operations — monitoring, alerting, troubleshooting and performance optimisation
Experience working with financial data, market data, exchange APIs or other data-intensive systems
Able to make architectural decisions and clearly explain the reasoning and trade-offs behind them
Comfortable taking ownership of systems beyond simply writing code
