Software Engineer, Site Reliability

About this role

About Upstart

At Upstart, we’re united by a mission that matters: to radically reduce the cost and complexity of borrowing for all Americans. Every day, we bring creativity, experimentation, and advanced AI to reshape access to credit, helping millions move forward financially with clarity and confidence.

As the leading AI lending marketplace, we partner with banks and credit unions to expand access to affordable credit through technology that’s both radically intelligent and deeply human. Our platform runs over one million predictions per borrower using more than 3,000 signals, powering smarter, fairer decisions for millions of customers. But the numbers only hint at the impact. Every idea, every voice, and every contribution moves us closer to a world where credit never stands between people and their financial progress.

We’re proudly digital-first, giving most Upstarters the flexibility to do their best work from wherever they thrive, alongside teammates across 80+ cities in the US and Canada. Digital-first doesn’t mean distant. We’re intentional about in-person connection through team onsites, planning sessions, and moments that spark creativity and trust. And whether you choose to work primarily from home or collaborate in-person from one of our offices in Columbus, Austin, the Bay Area, or New York City (opening Summer 2026), you’ll have the support to work in the way that works best for you.

If you’re energized by tackling meaningful problems, excited to innovate with purpose, and motivated by work that truly matters, we’d love to hear from you.

The Team

Upstart’s Site Reliability Engineering team enables engineers to operate reliable, resilient, and observable production systems at scale. We build the platforms, tooling, automation, and operational practices that help teams understand system health, respond effectively when things go wrong, and continuously improve the reliability of the services they own.

Our goal is to make reliability an integrated part of how software operates at Upstart. We provide shared observability and reliability capabilities, improve incident response and operational readiness, automate recurring operational work, and use system and customer data to identify where reliability investments will have the greatest impact.

SRE partners closely with product engineering, Cloud Platform, Delivery, Developer Platform, Security, and other infrastructure teams. SRE provides shared reliability capabilities and operational practices, while engineering teams remain accountable for the reliability and operation of the services they build.

The Role

As a Software Engineer on the Site Reliability Engineering team, you will build and operate systems that improve the reliability, resiliency, and observability of Upstart’s production environment.

You will work across observability platforms, reliability tooling, incident response systems, operational automation, and resiliency capabilities. You will independently deliver well scoped engineering projects, contribute to technical design, and use production data and operational experience to improve systems used across engineering.

We are looking for engineers who are thoughtful and intentional about how AI changes software development and operations. You should be comfortable using AI throughout the engineering lifecycle, including understanding unfamiliar systems, investigating production behavior, planning implementation, accelerating development, validating changes, and automating repetitive work. We expect engineers to continually develop more effective ways of working with increasingly capable AI tools and to apply sound engineering judgment to where they provide the most leverage.

How you’ll make an impact

• Build and improve the tooling, services, and automation that help engineers understand and improve the reliability of production systems

• Develop shared observability capabilities that make metrics, logs, traces, service health, and customer impact easier to understand and act on

• Improve incident response and operational readiness through better tooling, automation, standards, and actionable production signals

• Build resiliency capabilities that help teams identify failure modes, reduce operational risk, and recover effectively from infrastructure or application failures

• Identify recurring operational toil and reliability problems and replace manual processes with durable software and automation

• Use AI as an integrated part of software development and operational problem solving, while identifying opportunities for AI enabled capabilities that improve incident investigation, observability, reliability, and engineering efficiency

Minimum Qualifications

• 3+ years of professional experience in software engineering, site reliability engineering, or a related engineering discipline

• Strong software development skills in one or more general purpose programming languages such as Python, Go, JavaScript, or TypeScript

• Experience designing, building, testing, and operating production software, internal tooling, or infrastructure

• Experience with cloud infrastructure, distributed systems, observability, monitoring, or production operations

• Experience participating in on call or incident response for production systems

• Demonstrated ability to independently deliver well scoped engineering projects, navigate technical ambiguity, and collaborate effectively across engineering teams

• Demonstrated experience using AI assisted development tools across multiple stages of the software engineering lifecycle, with an interest in continually evolving how you use these tools as their capabilities advance

Preferred Qualifications

• Experience with Kubernetes, AWS, infrastructure as code, and cloud native production environments

• Experience building internal reliability, observability, incident management, or operational automation tools

• Experience with observability platforms such as Data
