Senior Software Engineer

We’re hiring a senior engineer who enjoys solving hard technical problems and wants meaningful ownership in a growing company.

This is a hybrid role based in downtown Denver, Colorado. We value in-person collaboration and build best when engineers spend meaningful time working side by side, whiteboarding, prototyping, and iterating together.

**Key Responsibilities**
* Ownership of meaningful systems with real influence over technical direction
* Direct access to product and company leadership
* Fast feedback loops and fewer layers between idea and implementation
* A collaborative environment where ideas are debated openly and decisions move quickly
* Visible impact. Your work will shape the trajectory of the company
* Design, build, and maintain scalable web applications and services using C# or Java, with a focus on reliability, maintainability, and performance.

WHAT “SENIOR” MEANS HERE

In our environment, senior engineers:

* Make sound technical decisions and clearly explain the tradeoffs behind them
* Step into ambiguity and create clarity for others
* Deliver reliably and adjust execution based on business priorities
* Elevate the quality of systems, discussions, and team standards
* Contribute to a culture of curiosity, accountability, and momentum

### Skills Knowledge & Expertise
###

Technical Depth and Rigor

You have demonstrated the ability to reason through complex systems and make sound engineering decisions. That evidence might come from:

* Designing and shipping production systems 
* Building products from 0 to 1 in ambiguous environments 
* Research, open-source contributions, or other technically rigorous work 
* Solving problems that required thoughtful system design, tradeoff analysis, or non-obvious technical decisions 
* Strong professional development experience with C# or Java.
* Experience designing, developing, and maintaining production web applications and services

You are comfortable reasoning from first principles, when necessary, rather than relying solely on established patterns. 
We care more about how you think and build than whether your background follows a traditional path.

Startup Adaptability

We are a mid-stage startup. Priorities evolve. Documentation is not always perfect. Sometimes the best path forward is not immediately obvious.

We are drawn to engineers who:

* Thrive in environments with evolving structure 
* Take ownership of learning new systems and domains 
* Proactively identify next steps rather than waiting for assignments 
* Stay anchored to business goals, not just technical elegance

Ownership, Pace, and Judgment

Strong candidates demonstrate:

* Clear reasoning behind architectural decisions 
* Ability to articulate tradeoffs, not just best practices 
* Awareness of business context when estimating timelines 
* The discipline to meet commitments 
* The judgment to increase intensity when the situation calls for it and to simplify when complexity is not justified

We value engineers who understand that great software supports real business outcomes.

Breadth and Curiosity

We appreciate engineers who:

* Have expanded their scope over time through new systems, domains, or increased responsibility 
* Are comfortable stepping slightly outside their core area when needed 
* See product, customer impact, and technical design as interconnected 
* Deep specialists are welcome, especially those who have increased complexity and ownership within their domain.

Experience That Is Particularly Relevant, Not Required

Exposure to complex or real-world data problems is compelling, including:

* Systems interacting with physical processes 
* Geospatial or spatial data 
* Combining multiple data streams to infer meaningful signals 
* Problems requiring modeling, interpretation, or non-obvious conclusions 
* Experience developing applications with .NET or Spring Boot 

Strength in some areas can compensate for gaps in others.

**Benefits**

* Salary range: $140,000-180,000 annual base
* Hybrid work environment (at least 3 days/week in Denver office)
* Health, dental, and vision insurance with low deductibles and premiums paid by company 99% for self and 50% for dependents and/or spouse
* 401K with company match (no vesting period)
* Student loan assistance
* Generous culture around time off, including: 
            * Unlimited PTO
            * 6 days of sick time per year 
            * 11 paid company holidays per year 
            * Up to 12 weeks of fully paid parental leave 
* Dog friendly office environment
