Full Stack Web Developer - Python, React, SQL (Mid-Level & Senior)

Level 12

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: $75-$100K (mid-level), $100K-125K (Senior/Lead).
    • 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 recently gave everyone an extra day off for Valentine’s Day just for extra quality time with their family.
    • 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
  • Healthcare: We contribute to an HRA to offset the cost of health insurance or healthcare expenses.
  • 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.

Level 12 is founded on biblical principles and has biblically informed goals. Accordingly, the reputation of Level 12 and the character of our employees is of utmost importance. You do not need to share our leadership's religious convictions, but you will need to share our commitment to the following principles:

  • Integrity: honest, trustworthy, reliable, ethical. We have high moral standards and we expect our employees to share those standards. If you use pirated software or media, don’t mind “tweaking” the truth, or think `porn == entertainment`, this is not the job for you!
