Meet Our Team – Quick Q&A with Emma
Tell us a little bit about yourself – who are you, and what is your background?
Hi! I’m Emma, born in Umeå in northern Sweden. I recently made a big life change—from hairdresser to software engineer. I took a two-year program in .NET System Development with AI competence, a hands-on education where we started building projects right away. It was incredibly fun and rewarding, and it really sparked my passion for development. I graduated in 2023 and have since worked at a startup, where I got to apply and grow my new skills. And now I’m thrilled to be here at a global, well-established company, continuing my journey as a Junior Software Engineer at COS.
What caught your interest in COS Systems?
Before I applied, I’d heard great things about COS from people who had worked with some of the employees here. When I walked into the office for my interview, everyone was so welcoming and warm—that feeling only grew stronger at my second interview. COS is a well-established company with a solid, well-structured system that I truly respect. The employees seem perfectly suited to their roles, and it’s clear everyone genuinely enjoys what they do.
What are your goals for the coming months?
I want to learn as much as possible about the company as a whole and grow into my role as a Junior Developer. I’m naturally curious and love understanding how things work. I’m also excited to get to know my colleagues—both here in Sweden and across other continents—and to better understand what everyone is working on at COS.
Why should people contact you and press the “connect with Emma” button?
I’m still new to the company and to my role as a Junior Developer, so I might not always be the right person for work-related questions just yet. But I do love a good chat, and if I can make someone smile, that makes my day. My hairdressing background means I’m naturally tuned in to listening and staying open to any kind of conversation. I’ve learned that when you do that, you often discover things you’d never have looked for on your own.
Tell us a fun fact about yourself.
I pick up different dialects terrifyingly fast—it honestly embarrasses me sometimes! I’ll be mid-conversation and suddenly realize I’m talking just like the person I’m with. Help!
I also lived for a year in Barcelona, and I spent some time living in Hemavan, a ski resort in northern Sweden, while working in Mo i Rana, Norway. Fun fact: the road between Hemavan and Mo i Rana is only about 10 miles, but it’s incredibly tough to drive. Some days the road completely disappeared under the snow, and once I was even chased by a moose (true story!). They’re way faster than you’d think—I had to speed off in my car to get away!
If you could swap jobs with anyone at COS Systems for a day, who would it be and why?
Since I’m still new, I haven’t learned exactly what everyone does yet. But from what I’ve seen, I’d choose Maren Buchmüller, Head of Marketing—just to try something completely different. It also seems like a lot of fun!
What’s your go-to productivity hack when things get busy?
Headphones on and 8D music—it’s magical how focused I become. I also make sure to take short breaks throughout the day; I prefer many small ones rather than one long break, and I always try to get some fresh air.
If you could instantly become an expert in one new skill, what would it be?
I’d love to instantly become an expert in more programming languages, cybersecurity, and machine learning.
What’s your favorite way to unwind after a long workday?
An audiobook while I’m driving or out for a walk is my go-to. A good workout—or a good meal paired with a great TV show—also helps me relax after a long day.
Lastly, what’s one word your friends or colleagues would use to describe you?
Welcome aboard Emma!
Updated UI Tools for Faster Daily Operations in Business Engine
Over the past year, our team has delivered a series of thoughtful UI improvements designed to make your daily work smoother, faster, and more intuitive.
In this update, Spencer walks through several key enhancements. First, the streamlined navigation: daily operational tools are now placed front and center on the left side, while deeper configuration menus move to a separate section, making everything easier to find. Up top, the notification center now includes release notes and improved alerts to keep you informed at a glance.
We’ve also added better visibility into integrations, allowing operators to quickly check system status and run syncs when needed. Search has been upgraded across the platform—from multi-order lookups to clearer default filters—making it quicker to find the exact data you need. The super search now highlights “perfect matches,” meaning one keystroke brings you straight to the right customer, order, or location.
Finally, fly-ins and customer/location cards have been redesigned to show more information on a single screen, reducing unnecessary clicks and helping you access diagnostics, history, and services faster than ever.
These changes may look simple, but together they create a smoother, more powerful user experience—one that helps you stay efficient and focused in your day-to-day operations. We hope you enjoy this sneak peek behind today’s advent calendar door and look forward to hearing your feedback as the UI continues to evolve.

How modern broadband turns “somewhere else” to “right here”
The gap we have to close
Too many areas still run on legacy networks and patchwork builds. Today’s life needs reliable, low-latency, symmetrical capacity. Only fiber scales for decades—not just product cycles.
Why rural communities get left behind—and what changes that
Traditional ROI favors dense metros. Rural means longer drops, fewer passings, thinner margins—the result being “have” vs “have-not” neighbourhoods. Communities are responding with public-private models: keep the physical network local, let private operators do what they do best, and share the upside as adoption grows—without the city having to “be the ISP”.
Open Access: the go-to model for turning demand into durable economics
Open Access separates the network into three layers—infrastructure (fiber/conduit), operations (active electronics), and services (ISPs and applications).One entity builds and maintains the fiber; many providers compete over it. Think airport + airlines: one shared, capital-intensive infrastructure; many consumer choices riding on top. This structure lifts take-rates (more choice → more buyers), reduces overbuild waste, and makes rural deployments cash-flow positive/ROI-positive on realistic timelines. It’s also future-proof: you can invite new providers or new classes of services (tele-health, smart ag, security) without touching the glass.
Two practical truths make Open Access work in the real world:
→ fun fact, one of our customers runs their network with a team of two
The COS Systems piece (move fast, stay efficient)
Proof in the wild
City of Superior, WI: stood up a marketplace where residents compare providers, order, and manage accounts—fast path from concept to day-one take-rate.
Clearwater County, Alberta, Canada: Arcadis + Calix + COS—shared fiber platform serving multiple last-mile technologies with a consumer-friendly marketplace.
Kitsap PUD, WA: community-owned, open access; thousands of passings, 6+ ISPs, automated sign-ups to settlements—scaling without extra headcount.
How modern broadband turns “nowheres into “somewheres”
Own the long-lived fiber infrastructure, invite competition through more customer choice, and automate the journey. You get higher take-rates, lower churn, healthier unit economics—and real options for people who were told to “move for opportunity.”
If you’re exploring how to take your “nowhere” to “somewhere,” let’s map demand, choose the right Open Access model, and stand up a marketplace your residents will actually use. That first flawless click on Join is closer than you think.

Meet Our Team – Quick Q&A with Björn
Tell us a little bit about yourself – who are you, and what is your background?
I am 44 years old and was born and raised a little bit outside of Umeå. I have an education in computer science at Umeå University.
What caught your interest in COS Systems?
I worked at COS for nine years, then moved to the audiobook industry, where I’ve worked for seven years to expand my views. Now I feel it’s a good time to come back and bring new experience and perspectives.
What are your goals for the coming months?
Getting back up to speed and bringing some good practices to improve our processes.
Why should people contact you and press the “connect with Björn” button?
I am always up for conversations about pretty much anything!
Tell us a fun fact about yourself.
I have an exceptionally acute sense of smell. While it offers little practical benefit, the drawback is that it makes me acutely aware of unpleasant smells.
If you could swap jobs with anyone at COS Systems for a day, who would it be and why?
Björn Wännman, it would be interesting to see things from the sales side.
What’s your go-to productivity hack when things get busy?
Not really a hack, but focus on a task at the time and try to ignore other things.
If you could instantly become an expert in one new skill, what would it be?
I’ve worked on both front-end and back-end development, but I’ve often relied on others for the visual design. If my design skills were stronger, I’d be more independent.”
What’s your favorite way to unwind after a long workday?
Usually, any form of exercise does the trick. Either a run, a long walk, or maybe a visit to the gym
Lastly, what’s one word your friends or colleagues would use to describe you?
Energetic
