Software Engineer, Backend Developer, Full Stack Developer

Kipsu is a growth stage Minneapolis-based technology company that has grown to over 100 employees. At Kipsu, we help service professionals Meet the Moment - from partnering with some of the largest hospitality brands in the world to working with clients in the multifamily and healthcare industries. Our best-in-class technology enables organizations around the globe to better serve their customers through streamlined messaging, data-driven performance metrics, sentiment analysis and workflow management.

As one of the Twin Cities’ leading tech companies, Kipsu has cultivated a reputation for a strong company culture and is consistently recognized by the Star Tribune as a Top Workplace.

Kipsu is hiring a back-end-focused, but full-stack capable, Software Engineer to join one of our cross-functional delivery teams in Minneapolis. You'll be part of our Services practice, the engineers who build the server-side applications, APIs, and data layer behind our platforms.

The team is currently building Kipsu's next-generation identity and access management system: the services that handle sign-in, enterprise single sign-on, and permissions for every Kipsu user. Team focus will shift over time as priorities change, so we're looking for someone who enjoys learning new parts of a system as much as going deep on one.

You’ll work across our technology stack:
Typescript, React, PHP, Kotlin, and more – ship features end to end, and help the team make sound technical decisions as we modernize the platform.

• Build complete features independently, from request handling and business logic through data persistence.
• Design and build well-structured REST APIs with clear resource models, consistent error handling, input validation, and documentation other teams can integrate against.
• Write efficient SQL, manage schema migrations safely, and use transactions and Redis caching where they fit.
• Apply secure design patterns as a matter of course, especially authentication, authorization, and input validation, which are central to identity work.
• Author technical designs for features and moderately complex work, covering integration points, testing, observability, and deployment.
• Instrument your code with structured logging and meaningful metrics, and design for failure when a dependency is slow or unavailable.
• Investigate and resolve bugs and production issues independently, finding root cause rather than patching symptoms.
• Write unit tests that cover edge cases and failure paths, and add coverage to existing code as you work in it.
• Review teammates' pull requests promptly and give feedback that improves the code.
• Work within our CI/CD pipelines and containerized environments, and troubleshoot build and deployment issues when they come up.

We encourage the use of AI coding assistants and agents throughout your day-to-day work. You will stay accountable for everything you ship, so you must review, test, and understand what a tool produces.

What you bring

• 3+ years of professional software engineering experience, with most of it on the back end.
• Hands-on experience full-stack experience in application development. You don't need to know our exact stack, but you need to have shipped code to production.
• Working experience with relational databases (MySQL, PostgreSQL, SQL Server, or similar): writing joins and aggregations, reasoning about query performance, and making schema changes.
• Experience building or consuming REST APIs, including HTTP methods, status codes, and error handling.
• A habit of writing unit tests and debugging systematically.
• Familiarity with Git, pull-request-based code review, and CI/CD workflows.
• Clear written and verbal communication. You raise blockers early, ask good…
