Backend Engineer III - Growth

ABOUT THIS OPPORTUNITY

onX is seeking a Backend Engineer with a passion for building reliable, well-tested backend services that solve user problems. Your focus will be on the shared platform infrastructure behind content experimentation, event tracking, and app-start fidelity. You will be a part of our Growth Infrastructure team, a horizontal platform team that supports Growth engineering across all of onX's verticals (Hunt, Offroad, Backcountry, Fish). This is a great opportunity to be a part of a dynamic, growing company focused on making an impact on the business, and to build infrastructure that other Growth teams rely on directly. This role will serve as a core backend contributor at onX and will report to the Growth Infrastructure Engineering Manager.

WHAT YOU'LL DO

Essential Job Duties & Functions

Build and maintain scalable services supporting Growth Infrastructure initiatives, including content experimentation and event tracking

Write unit, integration, and acceptance tests

Participate in architectural discussions and contribute design proposals for our services

Collaborate effectively with other engineers, PMs, and cross-functional stakeholders (mobile, BI, marketing)

Leverage and extend existing onX services rather than reinventing them

Proactively identify and use AI workflows that increase velocity while not degrading quality.

Participate in an on-call rotation to support backend services after work hours

WHAT YOU’LL BRING

Bachelor's degree in computer science, computer engineering, or equivalent experience

5+ years of professional software development experience, primarily in API development, is required

A shared passion for and ability to demonstrate onX's Company Values

Permanent US work authorization is a condition of employment with onX

Ability to travel quarterly for multiple days to a corporate office or other onX strategic location, such as a Basecamp

ADDED BONUSES

Though not required, we would be thrilled to consider candidates with any of the following:

Experience with Go or similar backend languages

Familiarity with Docker, Kubernetes, and infrastructure-as-code technologies such as Terraform

Familiarity with a major cloud platform (Google Cloud Platform preferred)

Exposure to A/B testing or experimentation platforms (e.g., Eppo)

THE ONX EXPERIENCE

onX is a distributed company with more than 400 employees across the country. We come together regularly to work in person and stay connected through regional basecamps and a culture that balances individual ownership with deep collaboration.

While we move quickly, we’re not a scrappy start-up. We operate with clear goals, structure, and frameworks that guide how we prioritize and execute. Priorities matter. While they may shift, data shapes how we evolve as our business, products, and the world around us change.

Clear priorities and structure don’t limit ownership - they make it possible. You’ll have the autonomy to define your work and make meaningful decisions within clear strategic boundaries. You’ll partner closely with others to solve complex problems and build solutions that scale across teams and platforms. Along the way, you’ll be supported with feedback, tools, and opportunities to grow your craft as you take on new challenges.

WHERE YOU CAN WORK

onX is a distributed company with employees across the U.S. We have physical offices in Bozeman and Missoula, MT, along with virtual workforce “Basecamps” in Austin, TX; Denver, CO; Kalispell, MT; Minneapolis, MN; Portland, OR; Salt Lake City, UT; and Seattle, WA. Basecamps are not physical offices; they are geographic hubs made up of remote employees who live within a 60-mile radius of the city center, creating opportunities for local connection and collaboration.

We have a strong preference for hiring candidates who live near one of our offices or within a Basecamp, and we prioritize candidates in these locations first. Candidates who live elsewhere in the U.S. may still be considered, provided they reside in a state where onX is currently able to employ team members.

At this time, we are NOT able to employ individuals whose primary work location is in: Alabama, Alaska, Arkansas, Connecticut, Delaware, District of Columbia, Florida, Hawaii, Illinois, Kansas, Kentucky, Louisiana, Massachusetts, New Jersey, New York, North Dakota, Ohio, Oklahoma, South Dakota, West Virginia, or Wyoming.

HOW YOU’LL BE COMPENSATED

onX is committed to compensating all employees fairly and equitably for their contributions. For this position, applicants can expect to make between $130,000 to $153,000 upon hire. The pay range will vary based on experience, skills, certifications, and education among other factors as required in the job description. In addition, full-time onX employees are eligible for a grant of common share options with a vesting schedule and a potential annual bonus of 10% based on company performance.

WHAT WE’RE OFFERING YOU

Competitive salaries, annual bonuses, equity, and opportunities for growth

Comprehensive health benefits, including a no-monthly-cost medical plan

Paid parental leave of 13 weeks for birthing parents and 5 weeks for non-birthing parents

401k matching at 100% for the first 3% you save and 50% from 3-5%

Company-wide outdoor adventures and amazing outdoor industry perks

Annual “Get Out, Get Active” funds to fuel your active lifestyle

Flexible time away package that includes PTO, STO, VTO, and paid holidays

PERFORMANCE ESSENTIALS

In this role, success is driven by cognitive abilities such as concentration and problem-solving, essential for our computer-centric tasks. onX will explore reasonable accommodations to ensure that individuals with diverse abilities can fully engage in and contribute to the essential physical and mental functions of the job. If you need assistance or accommodation, please contact us at PC@onxmaps.com.

Position open until filled.
