What the job involves
- At Affirm, security is integral to our mission of building honest financial products and driving the company’s long-term success
- The Security Operations and Resilience Engineering (SOR) program serves as the foundation of our preventive and responsive efforts to safeguard Affirm’s assets and infrastructure
- As part of our Security Team, you’ll join a group of passionate, highly skilled professionals redefining fintech security through collaboration, innovation, and a team-first mindset
- We’re seeking an experienced Staff Security Operations Engineer to lead our Detection & Response program in the UK, helping shape the next phase of our global Security Operations as Affirm expands internationally
- In this role, you’ll serve as the technical lead for company-wide initiatives across Logging, Detection, and Response in a highly engineering-driven, cloud-native environment
- As the primary Response Lead for Europe, you’ll coordinate incident response efforts, guide investigations to resolution, and partner closely with Legal and Privacy teams to ensure compliance with regulatory requirements
- You’ll also play a key role in scaling operational capabilities including architecting and building logging & detection pipelines, and developing response procedures that enhance our global security posture
- Additionally, you’ll participate in on-call rotations and serve as the engineering escalation point for complex security incidents
- This role is deeply cross-functional, collaborating with teams across Security, Engineering, Infrastructure, and Privacy/Legal to strengthen and scale our security operations

- Lead and expand Affirm’s Security Incident Response Program within Europe, shaping the Detection & Response strategy for international growth
- Lead the design and implementation of compliant security data strategies - partnering with Legal and Privacy to interpret regional regulations (e.g., GDPR, DORA) and determine how to structure, segregate, or manage key Security Operations tooling and data across international environments
- Act as Incident Commander during large-scale security events, guiding teams through containment, remediation, and post-incident reviews
- Serve as the technical escalation point for investigations and incidents in a hands-on capacity
- Develop and refine incident response playbooks, detection pipelines, and automations that scale globally
- Provide briefings and updates to diverse audiences, including executive and technical leadership
- Contribute to our detection program by creating advanced detections based on frameworks such as MITRE ATT&CK

- Engage externally with the broader security community through talks, publications, and knowledge sharing
Our take
Affirm offers point-of-sale loans to consumers, working with merchants like Shopify, KAYAK, and Walmart. Buy now, pay later transactions have grown in popularity in recent years, and this business is tapping into the market with a totally different approach to credit - by delivering the Affirm card, the first US debit card with the option to pay-over-time.
Boasting over 21M consumers and 337,000+ merchants, the company offers flexible payback options, ranging from 3 to 36 months. The interest rates run between 0% and 30%, so, while they are not necessarily the cheapest option, Affirm prides itself on having no fees for late payments, no hidden charges, and total transparency about what people will pay before they take out a loan.
Affirm collects payments from the customers and pays the merchants directly, shouldering the risk itself. The company has boosted its market share, expanding its availability beyond the US to include most of Canada, and continues to launch new features and create new partnerships towards bettering its offering.
