Job description

We are looking for a Python Software Engineer to join our Client Success Team. The vision of the Client Success Team is to establish a proactive, client-aligned feedback loop that accelerates high‑impact feature delivery for the Validus Horizon platform. By doing so, the team enhances internal efficiency and delivers greater external client value. This positions the Client Success Team not just as a support function, but as a strategic driver of product evolution, revenue enablement, and client engagement. As a Senior Developer within this team, you will take ownership of small‑to‑medium scope enhancements from idea to production, driving measurable business impact. You will work cross‑functionally with business leads, tech teams, and clients to translate complex financial and operational requirements into robust, scalable solutions. You will also play a leadership role within CST initiatives, ensuring delivery of results, high accountability, and technical quality.

Key Responsibilities

• Lead the end‑to‑end delivery of high‑impact features and enhancements for Validus Horizon, from technical design through deployment and post‑release feedback
• Own multiple concurrent CST initiatives, ensuring timely execution with clear stakeholder communication and transparency
• Design and implement full stack solutions (backend services, APIs, data pipelines, and frontend components) aligned with Horizon architecture and best practices
• Build and maintain robust ETL processes (data ingestion, validation, transformation, reporting, SFTP/API integrations) to enhance data availability, and client workflows
• Collaborate closely with business stakeholders to refine requirements, define acceptance criteria, and quantify business value
• Contribute to technical scoping and effort estimation as part of the CST ranking and prioritisation process
• Improve system performance, reliability, and scalability across Horizon components (e.g., RiskView, TradeView, PortfolioView)
• Act as a technical mentor within the CST, promoting high standards in code quality, documentation, testing, and delivery
• Support stakeholder and client meetings by presenting technical solutions, trade‑offs, and implementation roadmaps

Requirements

• 3‑5 years of professional software development experience
• Strong academic background in a quantitative discipline (Mathematics, Physics, Financial Engineering, Computer Science, etc.)
• Strong experience in Python or a similar backend language used for data processing and financial applications
• Full stack development experience (backend services, APIs, databases, and modern frontend frameworks)
• Experience designing and maintaining data pipelines and integrations (APIs, SFTP, structured market/portfolio datasets)
• Proven ability to lead small‑to‑medium scale projects with high accountability and ownership
• Strong interest in financial markets, with exposure to FX and interest rate products
• Ability to communicate complex technical and financial concepts clearly to both technical and non‑technical stakeholders
• Strong attention to detail, prioritisation skills, and ability to manage multiple parallel initiatives

Preferred Qualifications

• Experience working with financial risk management software or platforms
• Experience in market data integration, trade lifecycle systems, or portfolio analytics
• MSc degree in a STEM field
• Understanding of risk modelling, pricing, or financial analytics concepts
• Experience working in client‑facing or consultative technology roles

Benefits

• Competitive remuneration package (salary + bonus)
• Health care
• Retirement plans
• Financial support towards professional qualifications
