Who is MANTL?

MANTL is a fast-growing NYC-based FinTech SaaS company on a mission to build technology that will help America’s financial institutions and their communities thrive. Think Shopify or Squarespace, but purpose-built for community banks and credit unions. We are drastically changing the landscape through modern banking software that empowers banks and credit unions to grow digitally.

Our flagship product, Online Account Opening, has quickly become considered best in class in our industry, showing clear and material performance beyond any of our competitors. Suffice it to say, our customers love MANTL.

Since launching our first product in 2017, we have built several new products, thoughtfully grown the team, and have become a market leader.

Who makes up our team?

People are our most important asset and the number one reason we all love working at MANTL. As a team, we value accountability, transparency and collaboration. We have agile teams, with clear, outcomes-focused goals.

We're a group of passionate technologists that support an open and transparent culture that helps foster productive and engaging discussions. We want to work with inclusive people who understand the importance of treating their colleagues exceptionally well - people who will gladly go out of their way to help others with things big and small.

We are always a work in progress and love hearing feedback from our team. MANTL was proud to be named as one of Crain's 100 Best Places To Work in 2020.

Senior Full-Stack JavaScript Engineer

MANTL is seeking a Senior Full-Stack JavaScript Engineer to help shape the future of banking technology. This role will be based in our NYC office or remote. You should be an expert in all things JavaScript and have a high-level understanding of how things work across the full stack. A demonstrable front-end or back-end lean as a full-stacker is great too.

Who You Are:

You love working with JavaScript in both the browser and server. You can build slick, performant, scalable user interfaces with a front-end framework, and can also build solid backend APIs to support an application's data flow.

You should have fully workable understanding of the full stack, but it's cool if you want to focus more on either front-end or back-end in this role. For the front-end, you're a pro at DOM APIs and know the best way to get browsers to do what you want. You've worked extensively with front-end Javascript frameworks, but are not strictly reliant on them to be productive. For the back-end, you also have a great understanding of Node.js/Express.js/GraphQL and are able to build straightforward server-side code that can communicate with our microservices to serve and support the front-end.

You have strong opinions about the latest ECMAScript constructs, linting, testing, package evaluation, code organization, component interface design, performant rendering and all the other building blocks of a great web applications.

You also love to work with other developers, share your knowledge and thrive working on a team.

  • 5+ years professional web development experience, working extensively with JavaScript
  • 1-2+ years writing React.js professionally (experience with other frameworks also considered)

An Insider's view of MANTL

What’s the vibe like in the office?

I was initially a bit apprehensive about the idea of working in the FinTech space, as I had heard horror stories of tense work environments, exceptionally long working hours and closed-off office culture. Mantl caught me off guard by rejecting these standards and offering a human-centric, open work environment for me to do my best work in.

Leo Wicht

Senior Front-End Engineer

What's the biggest problem your team is solving?

Banking technology is falling far behind the consumer fintechs out there, yet millions of customers in the US still use community banks. Banks need better customer-facing products, or they will disappear.

Mike Bosserman

VP of Growth

How does the company support your career growth?

While working at Mantl, I have been tasked with a variety of diverse and important projects that have given me the opportunity to learn new technologies, design patterns, and best practices. In addition, I have been given a level of autonomy and responsibility over my work that would not have been possible at a larger company.

Thuy Dao

Software Engineer

What is your vision for the company?

Our vision for MANTL is to be the technology platform that powers our financial ecosystem. We're starting with the regional and community banks in the U.S. who are reliant on crumbling legacy infrastructure, and need our help to give their customers and employees modern tools and experiences.

Nathaniel Harley

Co-founder, CEO

What makes someone successful on your team?

At Mantl, we empower everyone to think big and constantly raise the bar to develop innovative solutions that not only meet, but exceed our customers’ expectations. We value transparency and integrity to do what’s right for our customers without compromise.

Director of Product Marketing
