Security Operations Engineer

Our Company Arch is a Series B financial technology company that automates the management of private investments, improving access, understanding, and the human experience of investing across asset classes. Private investments such as venture capital, hedge funds, and private equity, make up roughly 25% of the investment universe. Traditionally, investors, advisors, banks, families, and managers track hundreds of investments in complicated spreadsheets, file folders, and busy inboxes. Not only is this tedious and time-consuming, but it is rife with opportunity for manual data entry errors, inconsistent reporting, and lost information. Enter, Arch. Arch delivers standardized data, documents, and insights in a single platform, avoiding the need to chase information across dozens or hundreds of ‘portals’. Our purpose is to save investors’ time while empowering them to make more informed investment decisions, leading to better financial outcomes. We are a fast-growing, dynamic team of 200+, serving over 400 clients, including several of America’s largest banks, families, and financial institutions. We’ve over doubled the size of the company every year since inception and we are looking to hire in all departments as we scale. The Role: As a Security Operations Engineer, you'll join our small, growing security team in a hands-on, execution-focused role supporting our vulnerability management and detection programs.

You'll work across the organization on a variety of security projects, from vendor due diligence to infrastructure security checks.

Maintain and improve security logging and audit processes to support SOC 2 and ISO 27001 requirements. Support the team on infrastructure security checks and assist with security investigations.

Hands-on experience with vulnerability management (CVSS, patch lifecycles) and detection engineering (SIEM, log analysis, alerting). An understanding of security fundamentals (OWASP, NIST, CIS Benchmarks, SOC 2). Experience with cloud infrastructure security, specifically AWS (IAM, VPC, Secrets Manager). Proficiency in scripting and automation (Python, Bash, or Go) and basic familiarity with reading code to assist with security investigations or automation tasks. A collaborative mindset and willingness to tackle a variety of security tasks across the team.

Prior experience with threat modeling or security design reviews. Relevant industry certifications (e.g., Security+, CISSP, AWS Certified Security).
