- Architect security controls across cloud environments (AWS, Azure, GCP) and on-premises infrastructure, ensuring consistency and defense-in-depth
- Partner with engineering teams to embed secure-by-design principles into application development, infrastructure automation, and CI/CD pipelines
- Conduct threat modeling, architecture reviews, and risk assessments for new and existing systems
- Provide technical leadership and mentorship to junior members of the security team
- Collaborate with GRC, SOC, and IT teams to ensure alignment with regulatory requirements applicable to financial services (e.g., SEC, FCA, MAS, DORA)
- Evaluate emerging security technologies and provide recommendations to leadership
- Develop and maintain security architecture standards, reference architectures, and design patterns

Required Qualifications

- 8+ years of experience in information security, with at least 4 years in a security architecture role
- Deep expertise in identity and access management technologies such as Okta, Azure AD/Entra ID, Ping Identity, CyberArk, SailPoint, BeyondTrust, or similar
- Strong understanding of authentication and authorization protocols (OAuth 2.0, OIDC, SAML, SCIM, Kerberos, LDAP)
- Hands-on experience architecting security controls in public cloud environments (AWS, Azure, and/or GCP) as well as on-premises data centers
- Proven experience working within the financial services industry, with an understanding of the regulatory and threat landscape
- Solid knowledge of network security, cryptography, endpoint security, zero trust architecture, and secrets management
- Experience with infrastructure-as-code (Terraform, CloudFormation) and scripting/automation (Python, PowerShell, Bash)
- Excellent communication skills, with the ability to influence stakeholders at all levels of the organization
- Bachelor's degree in Computer Science, Information Security, or a related field (or equivalent experience)

## Preferred Qualifications

- Industry certifications such as CISSP, CISSP-ISSAP, SABSA, CCSP, or cloud-specific security certifications (AWS Security Specialty, Azure Security Engineer)
- Experience with workload identity, service mesh security, and Kubernetes security
- Familiarity with quantitative trading, low-latency, or high-performance computing environments
- Experience contributing to open-source security projects or security research communities

## Company Overview
- **One-liner**: Squarepoint Capital is a leading global quantitative investment manager that uses a rigorous scientific approach and state-of-the-art technology to construct diversified, systematic strategies for institutional clients.
- **Entity Type**: Private (no disclosed external funding; spun out from Barclays in 2014)
- **Headquarters**: New York, New York, United States
- **Founded**: 2014 (as an independent firm; the underlying business, nQuant, dates back to 2000 within Lehman Brothers and later Barclays)

## Products & Services

The majority of investments are based on rigorous backtesting on historical data.
- **Technology & Data Platform**: A custom, nimble, and forward-looking software stack that enables seamless integration between research and trading, executing millions of trades per day. Includes low-latency trading systems and a world-class data infrastructure.

## Market Standing
- **Valuation / Market Cap**: Not publicly disclosed

## Competitive Advantages
- **Deep heritage**: The team’s quantitative roots trace back to 2000, with a proven track record through multiple market cycles.
- **Scientific rigor**: A disciplined, research-first approach that relies on backtesting and systematic execution rather than discretionary bets.
- **Scale and technology**: Executes millions of trades daily using a highly custom, low-latency platform developed in-house.
- **Global diversification**: Strategies span asset classes, geographies, and trading frequencies, reducing reliance on any single market or style.
- **Culture of ownership**: Privately held and led by its founding partners, fostering long-term thinking and accountability.

## Strategic Focus
- **Diversification**: Continuously expanding into new asset classes, trading frequencies, and geographies.
- **Technology investment**: Ongoing development of proprietary software and data infrastructure to maintain a competitive edge in research and execution.
- **Talent acquisition**: Aggressively hiring quantitative researchers, software engineers (C++, Python), platform engineers, and operations specialists across global offices.

## Why Work Here
- **Culture**: Collaboration across teams, a flat structure with a strong sense of ownership and accountability, and a focus on intellectual curiosity.
- **Work environment**: In-office for most roles (offices in New York, Boston, London, Paris, Singapore, Bangalore, etc.). Some roles offer a remote work program, but the majority require physical presence.
- **Benefits**: Generous parental leave, health insurance (medical, dental, vision), 401(K) matching, disability and life insurance, paid sick days, generous PTO, paid volunteer time, free snacks and drinks. Offices are designed for in-person collaboration.
- **Engineering culture**: Technology is considered core to the business; engineers work closely with quantitative researchers to build and optimize trading systems. Emphasis on C++, Python, Kubernetes, and low-latency systems.
