We’re hiring a Software Engineer III to join our team. Our Level 3 Software Engineers are independent team members who can not only organize their own daily work in a productive manner but also effectively estimate their work and stay aware of prioritization on their projects. Read on to learn about us, what it’s like to work with us, what we’re looking for, and our hiring process.

Who we are

Tandem is a technology and innovation studio that specializes in product definition, custom software, and software managed services. We create custom software that inspires people and drives business forward. As a talented group of thinkers and makers from many disciplines, we are brought together by a shared goal: bring talented designers and engineers together to solve meaningful business problems. We always focus first on people — our clients, their customers, and our team — by collaborating to solve meaningful business challenges. We enjoy designing and building ambitious digital products and tools.

What it’s like to work with us

As a consultancy, we have the opportunity to solve a lot of different problems. We work directly with our clients in small teams, building and providing guidance on products, and collaborating with designers. Our unique approach to consulting leads to a better developer experience and a higher quality of work life.

As engineers, we love well-tested, maintainable, and clean code! We are always encouraging each other to write better code through pair programming and code reviews. We’re generalists and strive to make sure that we’re choosing the best technology to solve our clients’ problems. Right now we’re loving Postgres, Rails, and React as our greenfield tech stack, but we occasionally have projects in the Python, Java, .NET, Node, iOS, or ReactNative ecosystems. Nothing is off-limits, so we never turn down the opportunity to learn a new technology! 

Our vision is to create a supportive, collaborative environment and empower people to deliver work they’re proud of. At Tandem, everyone teaches and everyone learns. Egos are low, and we're all genuinely interested in seeing everyone else succeed.

  • Reliably complete necessary project management tasks in addition to technical tasks

How we work and our benefits

We care deeply about our team and strive to provide flexibility and benefits so each person can prioritize the things they care about. 

For example, our core working hours are from 10am-4pm in your local time zone. The goal of core hours is to ensure that we can pair and collaborate in a high-bandwidth way during the majority of our workday while allowing us the flexibility that real life requires. You may notice that 10am-4pm for five days doesn't add up to 40 hours - yet 40 is generally what we expect to do. How you organize your work time outside of core hours is at your discretion, whether this is early mornings, late evenings, or weekends (though weekend work is not recommended).

Our other benefits include

  • Healthy work/life balance with no overtime requests
  • Competitive annual salary ($105,000-$130,000)
  • 100% employer paid medical, dental, and vision plans for employee, spouse, and family
  • 100% employer paid life insurance policy
  • 100% employer paid short-term and long-term disability insurance
  • 3 weeks of paid time off to start, increasing by 1 week each year up to 5 weeks off
  • 3 paid conference days each year
  • Annual learning budget for conferences, courses, online training, books, etc.
  • Eligibility to enroll in the Tandem retirement plan with 3% employer matching after 6 months of employment

Our hiring process

We use a 4 step process.

  1. Application
  2. Phone screen
  3. Take home code challenge
  4. Remote in-person interview

The first step in our process is to fill out our application form. You will be asked a few questions on that form. We value thoughtful responses and will disregard applications without them.

If we decide to move forward, we’ll follow up with you to schedule an initial phone screen with one of our engineers. Our phone screens are non-/low-technical. We won’t be grilling you on database design but are interested in learning about your career trajectory, professional experiences, and what interests you.

If that goes well, we’ll send you our take-home code challenge. We know that everyone has different responsibilities and priorities in life, and we want to give you the time you need to shine. You will have 10 days to complete your challenge and submit it. 

Once submitted, we’ll do an internal code review to determine if we’d like to do an in-person interview. If we choose not to move forward, we’re happy to schedule a call for feedback.

Finally, the last step in our process is a remote in-person interview. You’ll have the chance to meet with many of our team members, extend your code challenge, pair with us on real clients and problems that we’re solving that day, and participate in a consulting challenge.
