The Opportunity

The Engineering Ecosystem Org exists to help engineers deliver member value with high speed and high quality. As a Senior Software Engineer, you will design, build, and operate scalable platform services and shared libraries that improve developer productivity, system reliability, and delivery velocity. In your first year, success means delivering complex platform capabilities end-to-end, contributing to architecture decisions, and raising engineering quality through strong technical practices and mentorship.

At Oportun, we move fast and we hold each other to a high bar. If you care about doing your best work while actually moving the needle for real people, you'll fit right in.
What You'll Do

Your day-to-day

• You'll design, build, test, deploy, and maintain scalable, reliable platform services and shared libraries.
• You'll contribute to platform and system architecture decisions with a focus on reliability, scalability, and developer experience.
• You'll write high-quality, maintainable code and model strong engineering best practices.
• You'll collaborate with Staff Engineers and peers to implement standards and patterns that support Continuous Delivery.
• You'll identify and address performance, scalability, and reliability issues across platform services.
• You'll participate actively in design reviews, code reviews, and technical discussions, providing thoughtful and constructive feedback.
• You'll drive operational excellence by improving monitoring, alerting, and incident response practices.
• You'll investigate root causes of production issues and implement long-term fixes to reduce on-call burden.
• You'll mentor and support junior and mid-level engineers through code reviews, pairing, and technical guidance.
• You'll partner with cross-functional teams to understand requirements and deliver solutions that create measurable business and customer value.
• You'll bring ideas for how we can do things better - proactively, not just when asked.
• You'll look for ways to use AI tools thoughtfully - to work smarter, reduce manual work, and make better decisions faster.

Who You Are

The right fit looks like this

You're a hands-on engineer who enjoys solving complex technical problems, navigating ambiguity, and improving systems that other engineers depend on. You take ownership from design through production, communicate clearly, and help raise the technical bar through mentorship and constructive feedback.

You're comfortable navigating complexity and don't wait for perfect information to move forward. You communicate clearly, give direct feedback, and expect the same in return.
