Atomic is growing a diverse and inclusive team of curious, creative people who love creating great software for our clients.

We’re looking for thoughtful problem solvers who are passionate about finding success for our clients, teams, and end-users through the human-centered design process.

Company

Since 2001, Atomic Object has designed and developed software products for web, mobile, desktop, and embedded devices. We were founded on the belief that not all software is created equal. Many people can write code, but it takes a close-knit team of passionate people to create exceptional, innovative products that change the way people do business.

We’re an employee-owned company with 100+ Atoms based in our Grand Rapids, Ann Arbor, Chicago, and Raleigh offices. Unlike many other technology companies, we have a flat organization. There is no corporate ladder to climb. As a company that values transparency, we practice open-books management. At Atomic, you can stay close to the craft of making software for your entire career without missing out on owning a part of the company and its profits.

Job Overview
POSITION

Atomic makers work on self-managed, cross-functional teams of 2-10 designers, delivery leads, developers, and testers. They collaborate to create products for our clients, from the idea phase through launch and beyond. Projects typically span 6 to 12 months, so you will have many opportunities to work with different people and tackle new challenges.

As a senior software developer at Atomic, your primary responsibility is creating a great experience for our clients by leading projects with empathy, clarity, and technical insight. You’ll guide teams, mentor fellow developers, and help clients make confident technical decisions. While writing code and tests  alongside other Atoms are an important part of your role, much of your impact comes from fostering collaboration, setting technical direction, and ensuring that both team and client succeed. Atomic promises clients a great experience and a great product. Software developers deliver on that promise by being kind, curious, positive leaders  who provide excellent high-level technical advice to a diverse set of clients.

A key way senior developers contribute to this experience is by sharing their knowledge and helping others grow.  Atomic lives by its “ teach and learn” value mantra. In this position, and in this role you'll spend time daily with mentoring teammates, teaching what you've learned over your career and learning from those around you. We also support learning through professional development by sponsoring annual conference attendance and involvement in local and national organizations.

Additionally, you’ll help broaden the impact of our services by serving as a technical marketer through opportunities like attending and hosting local developer meetups and contributing to our shared company blog.
