Lateral Group · Maastricht, NL ·
Lateral stands for technology excellence.
We’re a profitable, award-winning design and technology company with over 20 years of experience launching bold ventures and transforming businesses. A globally distributed team of 200+ experts united by a shared purpose: the continuous pursuit of quality.
Our clients come to us for results, quality and craft - and stay because we keep raising the bar.
Our mission is simple: design and build great products.
What sets us apart isn’t just the talent of our team - it’s the way we work:
We Have A Bias For Action & Results.
We are doers - we spot the gaps, connect the dots, anticipate what’s around the corner and take action. We move fast, stay focused, and let the results - not the effort - speak for themselves.
We Work On Time, On Budget, On Quality
Discipline is our edge - a commitment we make to each other, to our clients, and to the standards we hold ourselves to.
We Care Deeply.
We care about our work and about each other. Care Is A Competitive Advantage.
Every detail matters. Every design, every line of code, every decision. Thoughtful by default.
We Do Things Right - Because It’s the Right Thing to Do
Right over easy. Integrity isn’t up for negotiation. We hold the bar high even when no one’s watching. We take pride in doing great work the right way - not the easy way.
We Keep Improving
The best teams keep improving and we’re never done learning.
We iterate. We reflect on what’s working and what’s not. Feedback fuels us, we receive it openly, and adapt quickly. Progress over perfection.
We’re Obsessed With Agility, Not The Agile Manifesto
We don’t chase dogma or rituals - we chase momentum. We adapt processes to fit problems, not the other way around.
We Take Ownership
Everyone leads something here. You will have room to run with ideas, and the trust to execute. That trust is built on how you show up: thinking things through, sweating the details, and following through.
As a Senior .NET Engineer at Lateral, you will:
Design and build scalable, resilient cloud applications on Azure using C#, .NET and SQL, delivering solutions that are secure, high-performance, adhere to our Coding Standards and “just work”.
Write clean, clear, and well-tested code, embracing software craftsmanship principles to produce robust, reusable and maintainable systems. You will ensure a high bar for code quality through comprehensive unit tests and attention to detail.
Take ownership of features end-to-end, from initial concept through deployment. You’ll often drive substantial product features as the key developer alongside an architect or product designer.
Mentor and support junior engineers, leading by example in code reviews and pair programming. You will offer constructive feedback that helps others grow, fostering a thoughtful, kind, and continuously learning team culture.
Provide technical leadership in architecture and design discussions, advocating for simple, elegant solutions. You’ll challenge unnecessary complexity and focus on pragmatic results.
Continuously improve the codebase through refactoring and refinement, balancing new feature development with paying down technical debt. You’ll adopt an iterative approach of tweaking and constantly improving the software to keep the system simple, stable, and adaptable.
Champion quality, reliability and scalability by implementing best practices in cloud operations (monitoring, security, CI/CD).
Example Projects You May Join:
Build an AI-powered healthcare platform to help detect diseases earlier.
Launch a new fintech product from the ground up.
Scale a global SaaS commerce system with millions of products
Whatever the challenge, you’ll be building software that changes lives and moves industries forward.

Real Impact: You’ll work on meaningful products that make a measurable difference - from healthcare and commerce to sustainability and next-gen tech.
Remote-First, Office Friendly: Work from wherever you’re most productive - whether that’s your home, a co-working space, or one of our offices. We’re a remote-first company, but if you’re near an office, you’re welcome to drop in, collaborate in person, or work onsite regularly.
We prioritize async collaboration, respect your time zone, and focus on outcomes over hours.
An Outstanding Team: Talented, kind, and hard-working people who care deeply about their craft - and about each other. No egos. No politics. Just professionals doing their best work.

Variety & Stability: We’re profitable, independent, and over a decade strong. Yet every project brings a fresh challenge. You’ll never be bored here.
We want to respect your time by being clear about what this role isn’t. You should skip this opportunity if:
You prefer well defined structure. If you gravitate towards a clear hierarchy, well defined roles and swim lanes, you may find our self-managed style challenging.
Distributed work isn’t your thing. If you find async communication, design documentation and being proactive without a manager nearby difficult, our setup won’t suit you.
Feedback doesn't excite you. We’re obsessed with quality and believe in continuous improvement. That means we give feedback that’s sometimes nitpicky. If refining the work until it’s excellent feels over the top, you are likely going to find working here frustrating.
Change makes you uncomfortable. We’re scaling and maturing. That means not everything is perfect yet. Priorities shift. Processes evolve. If ambiguity is uncomfortable, this may feel bumpy.
However, If this sounds like fuel, we’d love to talk!
