You write high quality code that is easily understood and used by others. * You thrive in ambiguity, and are comfortable moving from low level language idioms all the way to the architecture of large systems to understand how they work. * Your growth and impact trajectory demonstrates that you have mastered gathering and iterating on feedback from your engineering and cross-functional peers. * You have strong verbal and written communication skills that support effective collaboration with our global engineering team. * This position requires either equivalent practical experience or a Bachelor's degree in a related field. ## Description As a Staff Software Engineer on the Order Platform team, you'll shape the systems that power every Affirm purchase after checkout - orders, captures, refunds, and settlement - and drive the technical strategy that lets our merchants and consumers transact reliably at scale. Your work raises the bar for reliability and simplicity across our engineering systems, keeping the platform highly available while defining the capabilities that unlock future product needs. We're a small, senior team doing high-leverage work within Financial Platforms. Today we're consolidating the internal platform behind Affirm's post-checkout APIs - drawing clean domain boundaries, migrating existing merchants, and enabling future product launches. You'll set technical direction, mentor a strong group of engineers, and own decisions that matter for years. What You'll Do * You will be responsible for setting technical strategy for your team on a year-long time scale, and help your team tie it together with critical, business-impacting projects. * You will collaborate across teams in the product development lifecycle by collaborating with product management, design & analytics to ensure technical sustainability, risks and trade-offs are well understood and managed. * You will act as a force-multiplier for your team through your definition and advocacy of technical solutions and operational processes. * You take ownership of your team's operations and availability by ensuring you have the right monitoring, triage rotations, playbooks, polcities, testing and alerting in place to support "keep the lights on" & on-call efforts. * You will foster a culture of quality and ownership on your team by setting code review and design standards for your team, and advocating for them beyond your team through your writing and tech talks. * You will help develop talent on your team by providing feedback and guidance, and leading by example. ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [MySQL Protocol Features You Should Be Aware Of](https://www.wearedevelopers.com/videos/100267-mysql-protocol-features-you-should-be-aware-of) - [Migrating half a million users to a new payment service provider](https://www.wearedevelopers.com/videos/730-migrating-half-a-million-users-to-a-new-payment-service-provider) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [How Much Does a Software Engineer Make?
