Through advanced execution and pricing technologies, we improve how financial markets operate.

An exciting new opportunity has arisen for a dedicated Employee Relations (ER) Specialist in our London office. Operating within our global People function, you will be the go-to ER subject-matter expert, supporting our teams across APAC, Europe, and the US. As a leading proprietary trading firm, we operate in a highly regulated environment and you will play a critical role in ensuring our People practices meet all compliance and ethical standards while fostering a positive working culture worldwide.

Core Responsibilities:

• Casework Management: Manage a varied and high-risk employee relations caseload across all regions, including disciplinaries, grievances, appeals, investigations, performance and capability concerns, with professionalism and cultural sensitivity, taking ownership of sensitive and complex matters as they arise.
• Change Management: Advise on and support the implementation of business-critical organisational change (including redundancies and international transfers), ensuring regional compliance.
• Manager Training: Develop and deliver targeted training for managers in APAC, Europe, and the US, building ER capability and confidence to address best practices and employee matters locally and globally.
• Policy Development: Draft, harmonise and implement robust HR and ER policies reflecting the latest UK, APAC, and US employment law, best practice and the regulatory standards that apply to trading environments.
• Risk Mitigation: Proactively ensure people-related actions are fully aligned with relevant employment law and internal requirements, supporting our regulatory obligations at all times.

• Employment Contract Project Management: Lead and manage complex employment contract projects, taking ownership of initiatives that require navigating multi-region requirements. Ensure all contract terms, including restrictive covenants, are compliant, commercially sound, and aligned with diverse jurisdictional and regulatory standards. Provide expert advice on the drafting and enforcement of non-compete, non-solicitation, and confidentiality clauses across multiple geographies.
• Conflict Resolution: Mediate disputes and lead fair, impartial investigations into complaints, ensuring an ethical and compliant approach throughout.
• Regulatory Liaison: Partner with Compliance, Legal and Risk teams as needed to ensure regulatory integrity in ER and people processes.
• Data Analysis: Monitor ER metrics (e.g., turnover, absences, trends) globally, identify themes, and present actionable recommendations for ongoing improvement.
• In addition to core Employee Relations responsibilities, the role may also contribute to broader HR initiatives and generalist activities where appropriate, ensuring alignment with organisational priorities.

Key Requirements:

• Qualifications: CIPD Level 5 (minimum) or Level 7 (preferred).
