About Montonio:
Montonio is an e-commerce checkout platform, loved by over 8000 merchants in the Baltics, Finland, and Poland. To date, we have raised nearly 19M € from Index Ventures and the people who built Wise, Bolt, and Pipedrive. We aim to be the go-to partner that merchants can rely on to grow their business, one superb checkout experience at a time. 🚀
The role:
At Montonio, we believe in true end-to-end ownership. As a software engineer, you'll dive into the world of e-commerce payments, checkout experiences, and shipping solutions with the autonomy to drive projects from conception to completion. You'll work directly with product managers, designers, and other engineers to shape ideas, architect solutions, and ensure their success post-launch.
What sets us apart is our commitment to engineer empowerment. We don't believe in traditional silos or specialized roles – you'll have the freedom to make informed decisions, observe real user behavior, and drive improvements that impact thousands of merchants. As a full-stack engineer, you'll be building merchant-first solutions while having the autonomy to truly own your work. If you're excited about this level of ownership and creating real impact, you'll feel right at home here.
What you will do:
- Own features end-to-end: from planning and technical design through development and deployment to post-launch monitoring.
- Work with your team to generate impactful ideas and proposals for features and product enhancements.
- Collaborate across teams to ensure we’re building the right thing the right way.
- Contribute to improving our engineering practices and culture, shaping Montonio’s future.
- Explore and learn new technologies that help us build better products for our merchants.
Our expectations for you:
- 5+ years of professional experience in software development.
- You care about how and why users interact with the product.
- You’re a skilled communicator – you’re proficient in written and spoken English and are able to work cross-functionally with designers, product managers, and other engineers.
- You work great individually, but even better with a team that you can depend on and learn from.
- You have a track record of taking ideas to execution – from conception to deployment to post-launch support.
- You enjoy writing testable, easy-to-extend, high-quality code.
Bonus points:
- Experience with high-traffic systems or financial services.
Technical specifics:
We believe passionate engineers can thrive in any environment, no matter the language or framework. Hence, there’s no need to be already familiar with all of our tech 😁. Here are some of the technologies you can expect to work with at Montonio:
- Node.js and TypeScript on the back-end (NestJS framework).
- Angular on the front-end.
- Our database of choice is PostgreSQL.
- We run our code in Docker containers and make heavy use of the AWS infrastructure.
What we offer:
You would be joining Montonio at a very opportune time. We’re still a team of 60 people and we are growing. It is a very exciting time that enables the possibility to be part of shaping the organization, our products, and Montonio's brand.

Why people love it here
-
Competitive salaries
While we wouldn't want people working with us only for money, we do value our people and believe that this should reflect in their compensation.
-
Actually transparent stock options
Everyone gets stock options and we take pride in telling you exactly how much your option package is worth instead of presenting you with obscure numbers that never get explained.
-
Really nifty health insurance
We're offering a diverse health insurance package that covers a wide variety of health-related topics such as dental care, seeing a therapist, getting new glasses and so on.
-
Hardware that works
Laptops, phones, headphones. We'll get you hardware that you can rely on for your work, depending on which cult you prefer following (i.e. Mac or PC, Android or iOS).
-
Meet great people and hang out at team outings
People thrive when you let out a bit of steam every now and then. Team outings, dinners, company events and general pizzazz.
-
No office politics
Never be afraid to speak your mind freely, it's okay to make mistakes and meritocracy will always prevail.
-
Flexible working
The office is a great place to mix, mingle and to spontaneously bounce ideas around. However, we get it - palm trees are also nice. Work remotely if you want to.
-
Things move fast here
Ideas get traction, we make fast decisions and are quick to execute.
Our values
💂 Ownership
When working with us, you’ll never be micromanaged or prodded to work. We trust people who we hire, so we let them make their own decisions.
💩 Learn from it, don’t dwell on it
Even the best of us make mistakes, it’s only human. Ask for help, fix the mess, tell your teammates and let’s make sure we learn from it, so we don’t stumble into the same mistakes twice.
🔍 Transparency & clear communication
Always ask the questions you have in your head, say what you’re thinking of and always stay honest with each other. We communicate our decisions and explain the thought processes behind them. Everyone who’s interested can ask questions and make suggestions about where we’re headed and why.
🚀 Ambition and initiative
We work with people who want to do things, who want to grow, who want to learn and with whom we can watch Montonio take off. If you see or hear something you’d like to help with, don’t wait to be asked, but stick your neck out and make yourself heard.
🎁 Delight our customers
At the heart of every little success is a merchant that’s happy with our products, our customer service or the daily interactions they have with us. Our success and growth is a byproduct of offering value to someone else on the market, never forget that.
🙇🏼 Stay humble
You get the idea.
