We are obsessed with the hero's journey at JobNimbus. Every person has a hero's journey—Hermione Granger, James T. Kirk, Frodo Baggins, Anna & Elsa, Nacho Libre, and even YOU! This is our "call to adventure" to come check out JobNimbus. What do you have to lose? You might make a few new friends, learn about a sick new company doing some amazing things, and maybe even land a new job!

Mission:

Lead the design and delivery of JobNimbus's payments platform, building secure, scalable systems powered by Stripe that enable seamless financial experiences for our customers. Partner closely with engineering, product, and finance to solve complex payment challenges while improving system reliability, scalability, and engineering quality.

What You'll Be Doing:

• Own the technical direction and execution of JobNimbus's payments platform, ensuring it scales reliably with customer growth and increasing transaction volume.
• Lead the design and development of Stripe-based payment systems, including subscriptions, invoicing, payment intents, and webhook-driven workflows.
• Act as the go-to expert for payments within the organization, guiding decisions around transaction flows, system reliability, and data integrity.
• Design and build backend systems using C#, Node.js, and event-driven architectures that handle high-volume financial transactions.
• Partner closely with product, finance, and engineering teams to deliver payment solutions that balance customer needs, speed, and long-term platform value.
• Drive alignment across teams when payment systems intersect multiple services, ensuring consistency in design and implementation.
• Break down complex problems into clear technical approaches and lead execution through hands-on contribution and guidance.
• Write production code alongside the team, especially on the most critical or complex parts of the system.
• Raise the bar on engineering quality through strong system design, testing practices, and operational reliability.
• Mentor engineers across teams, particularly in distributed systems and payments-related challenges.
• Lead initiatives that improve transaction reliability, billing flexibility, and system performance.
• Ensure systems meet expectations for security, data protection, and operational stability in a financial context.
• Leverage AI-assisted tools to improve development speed, reduce repetitive work, and enhance system quality.

What Makes You the Hero for This Job:

• 8+ years of software engineering experience with a track record of building and scaling production systems.
• Strong hands-on experience with Stripe and payment systems, including subscriptions, billing, invoicing, and webhook-based integrations.
• Solid understanding of payments concepts such as idempotency, transaction flows, and data consistency (you don't need to be a fintech lifer, but you know what can go wrong).
• Proven ability to lead technical decisions within a domain and guide other engineers toward strong solutions.
• Strong backend development experience in C# and/or Node.js.
• Experience building and operating distributed systems, particularly event-driven architectures.
• Ability to balance speed and quality, making pragmatic decisions that move the business forward without creating long-term risk.
• Comfort working across teams and stepping in where systems or ownership boundaries are unclear.
• Experience contributing to critical systems in production, including debugging, scaling, and improving reliability.
• Track record of mentoring engineers and raising the overall quality of a team.
• Experience with cloud infrastructure (AWS) and building highly available systems.
• Strong understanding of API design and integrating with third-party services.
• Experience with observability, testing, and maintaining production systems.
• Infrastructure as Code (Terraform)
• Database management and design (SQL, NoSQL). Knowledge of Couchbase a plus.

Superpowers:

• Extreme Ownership. You own the outcomes, drive initiatives, and solve problems proactively. If you need direction and someone to hold your hand, this job is not for you.
• Customer Obsessed. Everything we build should leave our customers saying, "Aw dip. This product is off the charts cool. Whoever wrote that code deserves a raise!"
• Proactive Learning. You stay ahead of the curve, continuously learning and implementing cutting-edge technologies.
• Team Commitment. You build, mentor, and lead a high-performance engineering team that delivers results together.
• Self Awareness. You know your strengths, weaknesses, and how to surround yourself with the right talent to succeed.
