  • Hands‑on experience with concurrency andshared memory tools.
  • Networking skills:ZeroMQ (or similar), low-level socket programming (TCP/UDP).

  • English: Upper-Intermediate or higher.

Nice to Have:

  • Familiarity with kdb+, TypeScript, and code generation tools.
  • Experience with Svelte is a plus.
  • Experience in Financial or Trading domains (FIX Protocol, OMS, Market data feeds like ITCH/OUCH).
  • Knowledge of Redis or other in-memory data stores.
  • Familiarity with the Qt framework.

Responsibilities:

  • Manage a team of 4-6 C++ and UI developers.
  • Collaborate closely with business stakeholders, including product managers and other stakeholders
  • Make regular, hands‑on code contributions.
  • Coordinate and collaborate with other technical teams across the organization.
  • Manage project timelines, deliverables, and cross‑team communications.

What we are looking for:

  • Autonomy: You excel at working independently, learning on your own, and figuring out large, unfamiliar codebases without external support.
  • Ownership: You are ready to take full responsibility for the core part of the system.
  • Assertiveness: You can clearly communicate your technical vision and demonstrate your project understanding effectively.

Project:

Customer: Global company based in the US.

Type: Fintech / trading platform

Product: A platform connecting global buyers and sellers of specialized commodities, providing trading, data insights, and market infrastructure used by large enterprises, financial institutions, and government agencies worldwide.
