Are you ready to help us modernize the massive wholesale trade industry by building software that digitizes complex invoicing and payment processes? At Wholesail, we are transforming the way food distribution works by replacing paper-based systems with a robust, automated platform. Since our launch in 2019, we have seen impressive growth and are backed by a team of serial entrepreneurs and investors with deep roots in fintech and major technology companies. We invite you to join our mission as we scale our platform to save businesses time and money.
What you bring
We are looking for a Senior Backend Software Engineer to join our team on a full-time basis in San Francisco, CA. You will play a critical role in our engineering department by focusing on our foundational accounting platform and expanding our product capabilities within the fintech space. Your daily impact will center on these core responsibilities:
- Taking ownership of our core accounting and automation systems while integrating with key partners like Stripe, Plaid, and Modern Treasury.
- Building and maintaining the foundational services, internal and external APIs, and platform components that support both our customers and our internal engineering team.
- Leading integration efforts to onboard new partners and developing revenue-driving features like automated bookkeeping services.
Requirements
The ideal candidate is a highly skilled engineer with at least five years of experience building reliable, web-scale products. You should possess a strong grasp of distributed systems, including microservices, message queues, and caching strategies. Proficiency with PostgreSQL is essential, as is a solid foundation in object-oriented design and data structures. We value candidates who are quick to learn new technologies, especially when navigating older accounting systems or ERPs. You must be comfortable working in a collaborative environment, possess excellent English communication skills, and have a disciplined approach to unit and integration testing. A background in cloud infrastructure, DevOps practices, and performance monitoring will help you thrive in this role.
What we offer
We are committed to building a supportive and high-performing team. While we focus on creating a world-class product, we also prioritize a culture of collaboration and professional growth. We offer the following:
- The opportunity to work on mission-critical fintech software that is actively redefining a trillion-dollar industry.
- A collaborative environment where you will work alongside experienced engineers, product managers, and founders.
- A chance to contribute to a rapidly growing company with significant customer traction and a strong pipeline of new features.
