Security Engineer, Privy

Job Overview

As a Security Engineer at Privy, you will help keep a rapidly growing platform secure through hands-on investigation, operational ownership, and building real code to solve real problems.

Company Context

Privy aims to make privacy and user ownership the default online by building simple, flexible APIs and tools for developers to build new products on crypto rails. Privy integrates across chains, third-party providers, and Stripe products.

Team Culture

Engineering at Privy involves high urgency shipping small iterations quickly, product taste with a focus on developer customers, and a security mindset where every engineer brings security to their designs.

Key Responsibilities

• Own security engineering work end to end: investigate alerts, findings, anomalies, and security requests; identify root causes; drive remediation; and clearly document outcomes.
• Participate in Privy’s security on-call rotation, helping respond to incidents, triage alerts, support vulnerability workflows, complete access reviews, and handle security escalations.
• Build and maintain production-quality tooling that reduces manual work, including alert enrichment, automated triage and routing, remediation workflows, access-review automation, and detection improvements.
• Lead focused investigations into suspected security events or compromises, gathering evidence methodically and coordinating the appropriate response.
• Proactively identify recurring sources of operational toil and engineer durable solutions that improve the team’s speed, consistency, and ability to scale.
• Partner with product and engineering teams to assess security risks, review lower-complexity designs and implementation plans, and make practical security tradeoffs to deliver quickly with quality and soundness.
• Contribute across Privy’s application, infrastructure, cloud, and product-security surface area, developing broad context while building deeper expertise over time.

Requirements

• Experience as a security engineer, detection engineer, or similarly hands-on engineer in a technically demanding environment.
• Strong software-engineering skills in Python, Go, Ruby, or a similar language.
• Experience investigating security signals, incidents, vulnerabilities, suspicious activity, or other ambiguous technical problems through to resolution.
• Familiarity with security operations, incident response, vulnerability management, detection engineering, access reviews, or related operational-security workflows.
• A strong understanding of web, browser, infrastructure, or cloud security, with the ability to apply that understanding across a broad range of problems.
• Good judgment under pressure, a methodical approach to investigation, and comfort working independently with agency despite incomplete information.
• Strong communication and collaboration skills, including the ability to explain technical findings, risks, and recommended actions clearly to clients and internal stakeholders alike.
• A self-directed approach to work: you notice gaps, make progress through ambiguity, and reliably close the loop.

Nice to Have

• Experience with AWS, GCP, or other cloud-security environments.
• Experience with detection engineering, security automation, incident-response tooling, or remediation pipelines.
• Bug-bounty experience, offensive-security exposure, or a strong attacker-minded approach to investigation.
• Experience with IAM, secrets management, secure production access, or secure CI/CD.
• Background in application security, infrastructure security, cryptography, or privacy engineering.
• Experience with fintech, payments, blockchain, or another diligence-forward financial product domain.
• Experience helping shape security operations, incident-response practices, vulnerability-management workflows, or a bug-bounty program.
