About the role
We are looking for a Security Engineer with 2-8 years of experience to be the first dedicated security hire at Slash and own the entire security program end-to-end. This is a generalist role – you'll work across the full stack from infrastructure hardening to application security, driving high-impact changes independently. You'll manage penetration tests, coordinate vulnerability remediation, and support compliance efforts while shipping real security improvements to a platform that processes billions of dollars in business spend. This person will report directly to the CTO and eventually become the sole owner of security at Slash.
What you will be doing
- Owning and building out Slash's security program from the ground up – finding gaps, prioritizing work, and driving changes across infrastructure and application layers
- Hardening cloud infrastructure and server configurations, including AWS, Kubernetes/EKS, and network security posture
- Managing recurring penetration tests and the bug bounty program, triaging vulnerability reports, and coordinating remediation across engineering teams
- Supporting compliance initiatives (SOC 2, PCI) by owning the engineering-related work needed to meet requirements
- Working cross-functionally with compliance, engineering, and other teams to push security improvements forward
About Slash
Slash is building the future of business banking, one industry at a time. We believe businesses deserve financial infrastructure tailored to how they actually operate.

Started in 2021, Slash is one of the fastest growing fintechs in the world and we power over ten billion dollars a year in business purchasing across numerous industries.

Slash was founded by Victor Cardenas and Kevin Bai in 2021. The company started as a neobank for self-employed individuals, with a particular focus on resellers Early reseller customers loved Slash because we provided them with virtual cards, enabling them to enter competitive raffles for limited-release products.
Within 11 months, we were processing $11M in monthly card volume, generating approximately $5M in annualized revenue. After the decline of the sneaker market in late 2022, we successfully pivoted by systematically reaching out to our largest customers to discover their new ventures. This led us to develop specialized solutions for ticket brokers and performance marketing agencies, finding product-market fit with these new verticals.
We are now forging a new path forwards, with 2 new initiatives: AI and global.
- AI: We are launching our agent Twin to customers for them to be able to manage their finances where work - Slack, iMessage, email and more. Twin will also unlock cross platform capabilities as we plug into their systems of record, letting you categorize spend directly into your ERP for example.
- Global: The ability for Slash to serve more geographies via crypto. Stablecoins are an enabling force that allow us to offer USD banking products to businesses all over the world.
Today, Slash processes billions in yearly card volume, has over $300M in annual revenue, and serves thousands of businesses across multiple industries.
