Security Engineer, Bridge

Stripe

WHO WE ARE ABOUT BRIDGE We're creating an entirely new payments platform, built with stablecoins, to simplify global money movement. Bridge enables faster, cheaper payments and borderless access to dollars via stablecoins. Through our APIs, businesses can send and receive funds across borders faster and cheaper vs. SWIFT and other fiat-only rails. Our virtual accounts enable international consumers and businesses to easily access, store, and spend US dollars. Our payouts infrastructure enables platforms to disburse USD to anyone globally. We believe many trillions of dollars will move and settle through stablecoin payment rails. Bridge is pulling this future forward. We have a small team of people who have previously built financial infrastructure at some of the world's leading companies (Coinbase, Stripe, Square, Brex, Upstart, DoorDash, Airbnb), and each and every one of them chose Bridge because they fundamentally believe that stablecoins will be a critical piece of financial infrastructure that allows for the improvement of global money movement. ABOUT THE ROLE As one of the first blockchain engineers at Bridge, you'll have the autonomy to work on projects that are truly global in scale and aim to give customers access to products they've never had access to. Many of the use cases that we work on today didn't exist several months ago, and that's because our team is dedicated to constant improvement for our partners and end users. Our engineers have outsized ownership over projects, so if you're looking for increased autonomy working on a completely greenfield opportunity, Bridge is the place for you. RESPONSIBILITIES • Build out multi-chain hot wallet infrastructure to support increased reliability of our payments. • Build smart contracts to increase hot wallet payment throughput. • Build smart contract platform to issue custom stablecoins across multiple blockchains (EVM, Solana, Stellar, etc.). • Build smart contract monitoring systems to detect anomalous events (especially related to minting and burning). • Design and develop blockchain-based applications and protocols to support stablecoin transactions and integrations. • Collaborate with cross-functional teams to understand business requirements and translate them into technical specifications. • Implement and maintain smart contracts, ensuring security and efficiency. • Perform thorough testing and debugging of blockchain applications. • Optimize blockchain performance and scalability. • Stay up-to-date with the latest developments in blockchain technology and integrate relevant advancements into our solutions. • Provide technical guidance and support to other team members. • Contribute to the overall architecture and design of our blockchain systems. WHO YOU ARE We're looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement. MINIMUM REQUIREMENTS  • Bachelor's or Master's degree in Computer Science, Engineering, or a related field • We're open to hiring engineers at various levels of seniority, but in general we'd look for somebody with 5+ years of experience • Strong proficiency in blockchain platforms such as Ethereum, Solana, or others • Experience with smart contract development using Solidity or other relevant languages • Deep understanding of cryptographic principles and blockchain protocols • Experience with decentralized finance (DeFi) and stablecoins is highly desirable • Knowledge of security best practices in blockchain development • An enlarged sense of ownership and the ability to lead and influence the design and direction of our products • An ability to thrive in a fast-paced environment • A growth mindset, constant curiosity, and fearlessness to dive into the unknown • Excellent written and verbal communication skills, including the ability to write clear technical documentation PREFERRED QUALIFICATIONS • Past experience working on crypto or financial products a plus, and while not required, we do look for people who are very passionate about building in this space • Experience with building API products a plus, but not required • Experience working with blockchain or distributed systems a big plus

Support and mentor product teams during the discovery phase to integrate security requirements into the initial design of new features. Define and manage company-wide security policies, translating complex compliance needs into actionable engineering practices. Lead the response to security incidents, driving the process from initial detection and analysis through to containment and long-term resolution. Drive the adoption of security awareness programs across the organization, using data to measure and improve our collective security posture. What we’re looking for We are looking for a professional who thrives in a decentralized environment and values enablement over enforcement. As we are highly invested in AI, you possess a strong understanding of how to enable secure development processes and data integrity within that space. You are motivated by the challenge of building scalable frameworks that reduce cognitive load for other engineers while maintaining the high integrity required of a regulated bank. Qualifications Several years of experience in security engineering or DevSecOps, ideally within Fintech or another highly regulated industry. Deep technical knowledge of AWS security services, IAM frameworks, and cloud infrastructure. Practical experience in incident management and the development of automated security tooling. Strong communication skills with the ability to influence technical roadmaps and drive alignment across distributed teams. Practical experience with EDR/XDR solutions and MDM frameworks is preferred. Why Qred? This is the place to be if you’re looking for a place to grow. Qred is growing fast, and our Qredsters along with it. With a non-bureaucratic organization and delegated responsibilities, we make sure there’s a short path from idea to action.

One Last Thing This is a full-time, permanent position based in our headquarters in Stockholm. We believe our culture thrives when we work together, which is why we have an office-first approach. To balance this with some flexibility, we have the option of working remotely one day per week.
