Kalderos is looking for talented full-stack engineers to join our Engineering team in our Chicago or Brookfield, WI locations.  We’re looking for someone who has a solid programming base with some prior work experience in a programming role and is willing to learn rapidly to best serve our clients.

Are you ready to join our amazing engineering team and help us change the world, one engineer at a time?

We are looking for

At Kalderos we are innovators, creators, and problem solvers. We look for people who share those passions while embracing differing opinions, skills, and life experiences. We view each application holistically; it's not just what you've done, but who you are and what makes you tick. 

Reading through job list requirements can be intimidating, and we get that! We encourage you to apply ESPECIALLY if you don't meet every qualification. Think of these requirements as more of a wishlist we have, and show us in your cover letter what you bring to the table beyond hitting a bunch of bullet points. As we said before, we value life experiences, varying skills, and how those can translate into applicable experience for the role you want here at our organization. 

We're changing the way healthcare performs, and we need someone who changes our mind about what a candidate can bring to the table. 

What you’ll bring

Below are some of the technologies our full stack engineers use at Kalderos.  We don’t expect our candidates to be experienced in all these skills coming in, but would have deep knowledge and prior work experience in 1 or 2 of the areas listed and eventually capable of tackling the other areas.

Some of the current front end technologies we use include:

  • Typescript
  • React
  • Redux

Some of the current back end technologies we use include:

  • .NET/C#

  • Front end and back end security tools

We know there are a plethora of other technologies that talented engineers use that can be mapped to our core technologies - such as Angular, Java, Node/Express, Python/Django, Ruby/Rails, Oracle, mySQL, etc.  That works for us as well.  If you have a good programming background we know we have the environment where you can get up to speed and make an impact quickly.

What you’ll be working on

  • Developing web applications used by our customers and stakeholders
  • Building common UI components that can be leveraged across our platform
  • Creating web services, common back end components and microservices
  • Architecting solutions that consider security, scalability, performance, extensibility and reusability.
  • Contributing to team and company objectives

Why is this a great opportunity for you? 

  • We work on cutting edge technologies and products.  We are continually evolving and building new product areas - providing many opportunities for individual team members to use their existing skills and grow in other areas as well.
  • We are a tight-knit and collaborative team of over 20 engineers.  We work hard, but have fun doing it.   Our team is made up of a diverse set of talented people - each bringing to the team their unique experiences.  We celebrate the diversity and inclusion within our team and Kalderos.
  • Our team members want to continually hone their craft - through a continuing education stipend, on the job opportunities, team lunch and learns and technical specialization groups that meet on a regular basis.
  • Our team members work in agile product teams - gaining valuable experience working with talented product managers, business analysts, design/UX, scrum masters and quality assurance engineers.  This is in addition to working with our other Kalderos teammates working on areas such as data science, marketing, customer success, sales, strategy, information security and finance.
  • Check out our company perks listed further below!

Personal attributes we are looking for

Strong communication and collaboration skills are required as we look for people to take on leadership initiatives.  We are not a typical Engineering team where people just want to put their heads down and code - but rather a team of engineers who want to actively participate in team and company initiatives not related to technical tasks.

  • Self-starter and motivated
  • Strong written and verbal communication skills 
  • A deeply ingrained sense of timeliness and urgency to resolve problems 
  • High standards for excellence as well as strict adherence to policies, procedures, and schedules 
  • Excellent organization skills and can work independently and multi-task with minimal supervision, while effectively identifying, organizing, and prioritizing multiple projects for themselves and others. 
  • You are comfortable working at a company that celebrates failure and rewards success.

Our vibe is a combination of trust, collaboration, and stimulation. We’re a young company with big ideas, super smart people, and an eagerness to make some real change. The general attitude is -- be yourself, dress how you want, and get ready to solve some big problems.
