Life at Lightspark
We asked a few members of our team to share a little more about their roles and what it’s like to work at Lightspark.
Rachel Malonson
Backend Engineer
What is the technical challenge you are most excited to solve?
I’m really excited about expanding the Lightning Network to support transactions and seeing how impactful that can be for the world.
Why did you join Lightspark?
I was equally excited about the vision and product as I was about the people I’d be working with, which is extremely rare. I worked on payments for a few years at my previous company and experienced a lot of the frustrations with the current systems first hand, so I was really excited about the possibility of making improvements there. Everyone on the team also has extremely impressive backgrounds and experience, so I knew it’d be a great opportunity to learn from some of the best.
What’s the team like?
To me it’s honestly the dream team. Everyone on the team is not only highly intelligent and hard-working but also really kind and generous. They are always willing to lend a helping hand and everyone works really well together to get things done.
Michael Gorven
Senior Production Engineer
What brought you to Lightspark?
The opportunity to work with a team of awesome people, building something new from the ground up. An environment of solving challenging problems is also something I really enjoy.
What does your team work on?
I work on deploying Lightspark’s code and supporting services to the cloud. In terms of code that includes database access, authentication and security all with the goal of enabling Lightspark to help customers manage Lightning nodes at scale.
What’s the best thing about working at Lightspark?
It’s fun and interesting. The team is ambitious and we have some of the best engineers I have ever worked with.
Yun Yu
Senior Software Engineer
Why did you join Lightspark?
This is my second job, I joined my last company post my PhD. I was at my old company for six years and focused on one specific area but had the opportunity to work in different parts of the business. What I have realized though is that the people I work with are important to me and so joining the team at Lightspark is the best decision I ever made - smaller company with huge passion.
What’s the technical challenge you are most excited to solve in your role?
I’m excited to build tools - like data infrastructure. Here I get to think about how to build new things that already existed in my last job and so it’s exciting to determine what we build to help the engineers that will come after me.
What have you learned at Lightspark?
I learnt a lot about how the Lightning Network works and how it can change the way people make payments. I’ve also learnt about what it’s like to work in a small company and build everything from scratch.
Vincent Durmont
Senior Software Engineer
What do you work on?
I’m mainly focused on the architecture of our customer-facing products: our APIs, our website, our SDKs and more. My goal is to enable our customers to use Lightning in a seamless and flexible way.
What’s something you enjoy about working at Lightspark?
I love the fact that we don’t get into long principled debates about the 'right way' of doing things. We look at the options together, analyze pros and cons and make fast decisions. Everyone commits and delivers but we are also working in new technological areas and so we aren’t afraid to change course and adapt if we need to.
What’s the team like?
There are a few things that stand out.
- An impressive combination of experience and expertise in the domains of crypto, payments and technology.
- The fact that everyone is so mission focused - it’s contagious.
- Everyone gets along and really cares deeply about one another.

Why did you join Lightspark?
I really believe that Bitcoin and Lightning are the best solution for decentralized payments and I’d like to do everything I can to help make them successful. This team is the right one for the job and I feel lucky to be able to work with everyone.
