Senior Android developer

Salary Competitive
Equity To be negotiated

Since COVID-19 pandemic, the labour market has been a mess. Hiring processes have been turned upside down, constant changes in the local policies are forcing companies to rethink how to find and manage staff. After bankruptcies and layoffs, people are demanding easier access to jobs nearby and paid fast.

Treamer rethinks how the labour market works. 

We have created the fastest job matching service for blue collar work, giving the local businesses an access to on-demand workers while keeping the platform accessible, open and easy to use for people looking for new ways to earn. We focus on blue-collar work which can be easily done by many: cooks, cleaners, people willing to spend some days on packaging phones - we help them to find jobs in no time.

Looking to make an impact? Want to rethink how a multi-billion dollar market works? 


Treamer is a Maria 01-based award winning startup, providing an on-demand staffing platform to connect businesses looking for blue collar workers with the members of the Treamer app. We have been building the app since 2015, pivoted it successfully and now need strong leadership for our tech team as we grow the business beyond the Finnish borders with the help of the latest raised funding. 

We have a clear vision and are working hard to get there but a lot needs to be done.

About the role

We’re looking for a Senior Android Developer to join our product team in Helsinki.

We are increasing the team of some of the most talented developers and designers in the region and building a great product for the world - this is where we need you.

  • Good communication and organisational skills

  • Works well as part of a team in a fast-moving environment

  • Good English

Great to have:

  • Insightful opinions about developing for mobile

  • Experience or interest in the whole development pipeline and process. We believe that developers know best what style of coding-testing-integration works best for them and support interest in improving things along the way.

  • Experience developing location aware mobile applications

  • Interest in looking at the other parts of the stack. You will communicate closely with fellow developers on the backend, Android and web side of things

  • Previous experience of startups or fast growing company is definitely not required, but very welcome

Your work environment:

  • We know our stuff and offer no-nonsense management. People at Treamer have at least 8 successful startups under their belt with at least 2 exists already happened (other ones continue flying high and have chances for good exists in the coming years)

  • We have worked on web services with millions of users (still running), we had our Android and iOS apps featured in the App Store and Google Play way more than once. Even some of our hobby projects sometimes dominate the less known app stores for months.

  • Agile development that makes sense. We do look at what our customers and users need, how they react to development and adjust accordingly. Yet we do not support any sort of “agile” crunches, do not buy the quickfix-driven development and give architecture the needed research time. You will receive help and you are expected to provide one.

Treamer is currently at the sweet spot where we have the concept validated, have we started with the second market just lately, we are growing fast, well, and are into doing it with great code. Our team is still small, the competition in the industry is fierce and there is a lot to do with the app. If you have that burning thing inside you that tells you to jump in, take a spin and show what you can do - this is your spotlight. 

Remember, “The people who are crazy enough to think they can change the world are the ones who do.”
