Job description

We are looking for a full stack (Python) web application developers to join the team at Level 12:

TL;DR: Why Consider This Position?

  • We give you a lot of information in the job description so that you can figure out if you'd really like to work here.
  • We have a commitment to transparency and offer a “no surprises experience” throughout the interview and hiring process.
  • We practice and preach sound development practices. You are likely to learn and grow as a developer while working here.
  • Our pay and benefits will be somewhere between good and great, depending on what you are used to and where you live (see below for specifics).
  • You will have the option of working from home or our office, whatever suits you best. Let’s make the most of our time and minimize commuting when not necessary.
  • We have a no-drama office policy. We value and cultivate enjoyable working relationships among team members.
  • We emphasize work/life balance and adopt policies that make sure our people don’t get burnt out. For instance, our PTO/Vacation policies are designed so that you actually use them.
  • A commitment to Agile Principles while not being enslaved to any particular methodology.
  • You have the skills and experience to be a mid-level or senior level full-stack web application developer. That is, you need to be able to architect & run with a medium sized project mostly on your own.
  • You like building full stack web applications with technologies like Python, React, SQL, etc.
  • You are committed to automated testing of all the software you write (our apps typically have 92%+ test coverage).
  • You recognized that there is a lot of idealism in the software development community and are not disenchanted with the the day-to-day realities of programming.
  • You like working independently but can contribute to a team as needed
  • If you apply, we will give you a yay or nay response. No black holes here!

Daily Responsibilities

Daily responsibilities primarily consist of coding database-driven web applications and other web-related development work. In a typical day, you will likely work mostly with Python based web applications using frameworks like Django or Flask that interact heavily with a database (PostgreSQL or MSSQL).  In the course of that work, you will have to interact with related technologies like JavaScript, React, HTML, and CSS/SASS.

This is not a design job. It will require a lot of in-depth programming and database work including the ability to architect maintainable code that gets the job done.

While we do prefer to do most of our back-end work in Python, we will occasionally take projects in other languages if they seem to be a good fit for us and the customer.

Some days you will jump from project to project as issues come up. At other times you may work primarily on one project for weeks or months.

The ability to take ownership for a project, engineer a sound technical solution, and “drive” a project to completion is essential.

Our customers have varied needs and so we tend to have varied responsibilities and projects. We have a focus on serving the customer and making software conform to their company rather than making the company conform to software.

We run our teams (two currently) in two week sprints.

What We Offer

  • Pay: $80-$105K (mid-level), $105K-$125K (Senior).
    • We are happy to talk about money as one of the first parts of our conversation so we don’t waste each others time if we aren’t in the ballpark.
    • Everyone wants to be paid as much as possible, but the economics of business usually require that we meet in the middle.
    • Our offer will take into consideration your salary history, experience, references, and a skills assessment.
  • Profit Sharing: In addition to a salary, our employees will earn a bonus based on how profitable our company is each year (roughly $1-2K annually).
  • One of the best things about working for us is that we really value work/family balance.
    • We rarely work more than 40 hours a week.
    • We know there are devs out there putting in 50-60 hours a week. We can give them 10-20 hours a week of their life back.
  • PTO/Vacation:
    • Everyone receives 3 weeks of PTO/Vacation per year.
    • Up to 12 sick days per year.
    • 9 Holidays
  • Flexibility: While we expect a regular schedule during normal business hours, we are pretty flexible when schedule changes are needed for legitimate reasons.
  • Telecommuting:
    • Remote candidates are welcome to apply.
    • Many of us work from home frequently, even those of us who are local.
    • We do have an office if you prefer to get away from home to focus on work.
  • We Care: It’s easy to say, harder to do. We all need to make a living, our company needs to be successful in the marketplace, and hard decisions sometimes need to be made. But, at the end of the day, we really care about our employees, their families, their needs, and their desires.

Candidate Feedback

GB, 8/2018

Well the work looks really interesting and appealing but more than that the job posting is like nothing else I've seen so far. It appears to be more thorough, personal, caring, and honest by far than any other I've seen. In my experience there are qualities present in a company's management that tend to permeate through all levels and find expression in many subtle ways. If I am reading into what I am seeing correctly then this would be an exceptional place to work. I'm not sure how to say it other than that. It was just kind of a feeling after looking over the page, that this is where I want to be.

JF, 10/2018

I'm extremely impressed with how much effort your organization puts into describing work opportunities! By far, this is the most helpful job posting I have ever seen. I intend to respond in a point-by-point fashion, as that seems to be the most efficient way to proceed. I hope to repay honesty with honesty.

JH 8/2018:

Like I mentioned before, I really like the whole interview process that you guys have.  That in combination with how you guys responded to emails, etc. gave me a very positive impression of your company and I am still interested in working with you guys someday.

LB, 8/2018

The feedback I received from [your first skills assessment] was amazing!  That was fantastic! I was really impressed with it.

KM, 9/2018

I just wanted to reach out and give you some really positive feedback. If I could go back in time and finish up those final interviews with you, I would do it in a heartbeat. I can already see a huge difference in personality between you and those who lead the company I joined -- and I think it speaks volumes. Keep being a great person!

I hope you found a great candidate in the end!

Company description

Who Are We?

Level 12 is development firm that specializes in building custom software for our customers.  We manage the entire process including planning, managing, and building software exactly as the customer needs it.

We serve customers in diverse industries including: railroad, automotive, manufacturing, and retail payments.

We set ourselves apart by digging into the customer’s problem until we can own it and then delivering highly functional software that brings significant value to the customer’s organization.  That may not sound unique, but the longer we do this, the more we encounter people who have been burned by bad development experiences with other firms.  We look for long-term relationships with our customers and have some that go back to 2005.

We may not be changing the world, but we are impacting the lives of our customers and their employees.  You don’t have to take our word for it, checkout some of our reviews by our customers.

Please watch the video on our website to learn why milk trucks are better than tanks (and learn more about our development process at the same time) (< 2 mins).

Emphasis on Development Best Practices

Behind the scenes, we are using software development best practices to ensure that the code we deliver is flexible, maintainable, and works well for the user for years to come.

We know what it’s like to work in a substandard development environment or culture that accepts or maybe even promotes practices that kill developer productivity and enjoyment. We work hard at promoting development best practices and ingraining them into our culture. If you come work for us, you can look forward to:

  • All projects managed in a DVCS (mostly Git, there might be a few obscure mercurial repos laying around that will eventually get converted)
  • Project management mostly on GitHub for pull requests, issue management, code coverage, CI integration, etc.
  • Developer friendly project setup: all our projects can be run locally on a developer’s machine.
  • Test-centric development methodology:
    • Asking “how can we test this” is ingrained into our engineering and development workflow.
    • We have Continuous Integration (CI) running for almost all of our projects for at least the backend code (Python mostly) and some of the projects also run the JavaScript tests in CI.
  • A focus on Agile Principles while not being enslaved to them.
  • A openness to changing our processes and using new technologies when those changes add value to Level 12 and/or our customers.

If you’d like to learn more about what makes us tick, our Chief Executive Developer (CED) gave a talk on the importance of CI and automation in an agile software development process (video on our website) and has given other talks and presentations on various topics.
