About VivCourt

We’re VivCourt, a Trading firm like you’ve never seen before. We use our smarts and leading-edge technology to trade on financial markets worldwide, but we’re saying no to how it’s always been done. We’re showing the industry it’s possible to make money and put people first.

Everything we do at VivCourt is designed to help you be your best. We’ve built an open, collaborative, and inclusive culture where you can thrive and perform because we believe profit is a by-product of a committed workforce.

Engineering @ VivCourt

Engineering is the backbone of trading here. We’ve laid a strong foundation, but plenty remains to be done. As an engineer, you’ll own meaningful projects - from refining systems to leading major upgrades - supported by a collaborative team that values well-designed solutions.

We’re looking for pragmatic engineers who are fast when it counts and precise when it matters.

Join our IT Operations Team

As a key part of our IT Operations team, you will maintain, troubleshoot, and optimize our high-performance, low-latency infrastructure. This role focuses on ensuring the resilience and security of systems located at global exchanges, running on enterprise bare-metal hardware, FPGA-accelerated components, and low-latency network architectures. You'll work directly on infrastructure where nanosecond-level latency decisions have real financial consequences.

Who you are:

• Proactive & Curious: You spot operational issues before they escalated and actively hunt for improvements.
• Analytical Thinker: You are detail-oriented with strong reasoning skills, allowing you to think several steps ahead.
• Agile Problem Solver: You respond quickly and confidently to incidents, staying composed under pressure and making sound decisions fast.
• Experienced Professional: You bring substantial experience (typically 5+ years) delivering precision and stability within complex, mission-critical infrastructure environments.

What you’ll do:

• Red Hat Enterprise Linux (RHEL): Support, tune, and optimize RHEL systems running on bare-metal hardware and hypervisors for low-latency, high-performance execution.
• Network Operations & HA: Maintain highly available routing and multicast environments using BGP, OSPF, PIM, and IGMP, with hands‑on experience across colocation and on‑prem switching and connectivity.
• Security & Resilience: Design and implement security controls and disaster recovery procedures for mission‑critical financial infrastructure, with direct input into risk and architecture decisions.
• Planning & Coordination: Lead maintenance windows and operational upgrades, coordinating across internal teams and external exchanges and colocation providers under time‑sensitive conditions.
• Automation: Improve our configuration management, observability, and operational tooling (Ansible, Zabbix, Python).

Why VivCourt?

• No shareholders. Our profits fund social impact.
• Performance + purpose. We aim to be one of the best trading firms in the world while contributing to a better one.
• Flat structure, fast decisions. You’ll have access, ownership, and autonomy.
• People-first culture. Real humans. Low ego. High standards
