Full job description

WHO WE ARE

At Basis, we empower agencies and brands with cutting-edge software that automates digital media operations. Our all-in-one platform supports seamless planning, reporting, and financial reconciliation across direct, programmatic, search, and social media.

We’re not just building advanced technology; we’re also building a culture where passionate, motivated individuals come together to drive meaningful change. Our commitment to inclusivity and growth ensures our employees thrive both professionally and personally.

With our headquarters in Chicago, we offer flexible work options across the U.S. and Canada, including remote, hybrid, or on-site at headquarters.

ABOUT THE TEAM

Our team sits at the nexus between the flagship Basis Platform application and our Demand-Side Platform, a real-time auction engine that competes in billions of ad auctions a day, each with a sub-100ms latency.

We implement features and workflows that surface the DSP capabilities making the functionality approachable for the novice and power users alike. The work is high-visibility, revenue-impacting, and customer-facing. The features and projects we take on reach across internal and external boundaries, services, and orgs. We deal in data, and lots of it! Implementation is not just code and structure, we consider resources, performance, and scalability.

WAYS YOU’LL CONTRIBUTE

You'll build net-new Basis Platform features, develop the integrations that bridge Basis Platform and our DSP, and extend the existing feature sets that our customers rely on every day. What makes you a great fit for the team:

WHAT YOU BRING TO THE TABLE

5+ years professional software development experience.

Proven experience designing, building, and scaling modern, production‑level front‑end experiences using React, with supporting back‑end work in Ruby on Rails.

Current with modern development practices, including AI-assisted and agentic workflows for code generation, debugging, exploring, and documentation.

Strong grasp of data modeling and system design.

Enthusiastic growth-oriented mindset.

BONUS POINTS

Bachelor’s degree in Computer Science, Engineering or related field

Experience with Spring Boot, Quarkus

Excited by a fast-paced product development environment

Passion for Ad-Tech

OUR TECH STACK

React/JS, Ruby/Rails, Java

This salary range reflects a typical compensation range for the role and level in most U.S. locations. Final compensation offered will depend on your location, experience, and skills. Total compensation may also include bonuses, equity, and competitive benefits.

Integrity in Hiring

At Basis, integrity is at the core of how we hire. To protect our candidates and our company, we verify identity, education, and employment history for all hires. Some roles may also require onsite or in-person interviews as part of the process. Any misrepresentation of identity, experience, or skills may result in removal from the hiring process or termination of employment. We value transparency and authenticity and expect the same from every applicant.

Anything Else?

Don’t have every skill listed? No problem! We know experience can be built in many ways. If you have relevant skills that aren't reflected in your resume, we encourage you to share them in an optional cover letter.

Life With Basis

We’re committed to our people’s growth and well-being because our success is tied to theirs. That’s why we’ve earned recognition as a top workplace, including: Ad Age, #1 Best Places to Work, WorkLife's #1 Most Committed to Work Life Balance, and the Chicago Tribune's Top Workplaces in Chicago. We offer competitive perks, including a flexible work week, 401k/RRSP matching, mental health support, paid sabbaticals, generous parental leave, flexible work options, and more.

Basis is proud to be an equal-opportunity employer. We celebrate all team members regardless of gender identity, sexual orientation, race or cultural background, religion, disability, age, and beyond.

If you need assistance with interview accessibility, please contact [email protected]. Your privacy is important to us, view our policy here.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
