Integration Engineer

Copenhagen, Capital Region of Denmark, Denmark · Engineering/Product


Who we are

We’re a team driven by the belief that we can radically change the world of work. We believe – and hear from our customers every day – that when an organisation understands itself better it can create more fulfilling jobs, and grow in ways never before imagined.

Enterprises big and small trust our products to provide visibility and clarity in areas once characterised by hearsay and uncertainty. With the insights delivered by Peakon, these organisations become more agile, responsive, and able to make the changes and investments that their employees care about most.

We’re in the business of creating great places to work, so it should be no surprise that this is our highest priority at Peakon. With ambitions as big as ours, we see individual growth and development as the key strategy for growing our business.

Trust and transparency guide everything we do here. You’ll find an open salary model, unlimited vacation, minimal hierarchy, and maximum freedom to develop and execute your own ideas. Our style of collaboration is based on honesty and friendship, and we always love making new friends!


With a rapidly increasing number of large-scale customers, we are determined to enable more and better ways to integrate Peakon with third-party systems like HRISs and BI tools. This effort will allow new customers to faster and more easily start using Peakon within their organization, use the platform continuously with minimal manual overhead, and enhance existing workflows with engagement data from Peakon.

Therefore, we are looking for an Integration Engineer to lead our efforts in three main areas:

You will work closely with our Integration Consultant and Technical Sales team to understand customer requirements, writing down specifications, as well as interacting directly with customers’ technical representatives to provide high-quality APIs and great developer experience.


Who you are

You are an engineer at heart, who loves to tinker and build things. You stay up to date on the latest technology trends and are able to evaluate the feasibility of new technologies for the problem you are trying to solve.

You are passionate about API design and open standards, with extensive experience using a variety of APIs across the web. You are familiar with best practices around API design, data processing and common technologies such as REST, GraphQL, OAuth 2, JSON, XML, etc. You have experience in technical support or interacting directly with platform customers in other ways, able to identify and break down requirements easily.

You are looking for an opportunity to grow your career within a highly skilled engineering team in a fast-growing company.

Our ideal candidate has...

We welcome your application even if you do not meet all of the criteria listed above, but are excited about the challenge of mastering this role. We know that skills are not static and growth is continuous, so we are excited to help you take your career to the next level at Peakon.

The tech

We make it a priority to stay on the cutting edge of tech. We are highly motivated by learning and growing in our roles, and constantly evolving is a key part of that.

The tech stack of Peakon centers around Javascript, with Node.js on the server and React on the frontend. We believe there is great value in a shared toolchain across the stack, enabling engineers to work on all parts of the system. Some tasks are better solved with different tools, and thus we use f.ex. Python for the data science parts of the system.

We are big fans of new JavaScript language features like async/await, and have made it a priority to stay up to date with the latest versions of Node. We are primarily hosted on Heroku and AWS, with an increasing number of our services moving to the latter. We use PostgreSQL (through RDS), Redis and ElasticSearch for storage.

We rely heavily on automated testing on all levels of the application, with thousands of tests checking every commit to our code base. We use CircleCI for hosted continuous integration to make sure our most recent changes are always available to test, and we deploy code to our production environment on a daily basis.
