Description

Join us as a senior Software Developer in Quantitative Analytics Engineering (QAE) Budapest to craft the next generation of our single security analytical modelling platform using C++23 and Python 3.

You will create new modules, applications, APIs, and observability pipelines to provide clients with novel ways of using our analytics.

You will understand our business processes, identify bottlenecks, and provide optimizations to improve our cloud compute performance.

As a senior developer, you will lead the development of scalable, high-throughput, low-latency analytical software in close cooperation with the Aladdin Financial Modelling team for valuation of fixed income products like swaps, bonds, private credit, and derivatives.

Challenging the status quo is our norm, and we excel in building modern systems and onboarding innovative technology like microservice architectures.

We are a diverse team with different ideas working towards the same goal.

Our dominant programming languages are C++ and Python.

We are passionate about what we do and hope you are, too!

Requirements:

  • Experienced in enterprise software development (5-7 years)
  • Qualified with a Bachelor’s degree or higher in Computer Science or a related field
  • Ready to lead. Work experience where you were responsible for or owner of an application or component. Willingness and ability to provide tutoring and mentorship to less experienced team members.
  • Pragmatic and solution-oriented
  • Eager to work as part of a software development team

You are familiar with:

  • C++17 or later
  • Python 3
  • Design patterns, Object-Oriented Design principles, and fundamental Algorithms and Data Structures
  • Software development tools (test frameworks, version control)
  • Continuous Integration

Nice to know:

  • Agentic development principles
  • C++ development tools (CMake, ninja, ccache, distcc)
  • Google Protocol Buffers
  • Unix systems (Red Hat, Ubuntu)
  • Profiling tools (gprof, valgrind, gperftools)
  • DevOps tools (Azure DevOps)
  • Scripting languages (bash, PowerShell)
  • Microsoft SQL
  • Azure Kubernetes Service (AKS)

Knowledge of finance and fixed income asset types is a plus but not a must. We will help to learn what is needed.

Our benefits:

To help you stay energized, engaged, and inspired, we offer a wide range of employee benefits including: retirement investment and tools designed to help you in building a sound financial future; access to education reimbursement; comprehensive resources to support your physical health and emotional well-being; family support programs; and Flexible Time Off (FTO) so you can relax, recharge, and be there for the people you care about.

Our hybrid work model:

BlackRock’s hybrid work model is designed to enable a culture of collaboration and apprenticeship that enriches the experience of our employees, while supporting flexibility for all. Employees are currently required to work at least 4 days in the office per week, with the flexibility to work from home 1 day a week. Some business groups may require more time in the office due to their roles and responsibilities.
