Listing Description

Do you want to secure products that connect thousands of diners to restaurants every day?

Can you balance security, product advancement, and maintainability to help us continue to ship secure web applications?

If all() of your answers to the above == True, keep reading; this might be the secure application environment you’ve been looking to protect and defend.

ChowNow is looking for a motivated and experienced Senior Application Security Engineer to join our team in our mission to develop efficient and developer focused security solutions. We are dedicated to identifying ways to increase developer velocity while ensuring security is baked into the SDLC. Our team is also focused on being a trusted partner to the engineering team by building strong relationships with developer squads and being viewed as enablers rather than blockers.

About Us:
ChowNow’s vision is to become the leading North American platform connecting diners and independent restaurants for at-home dining.  The ChowNow Platform continues to grow its product offerings and bring restaurants and diners closer together. Our marketplace provides a commission-free ordering for restaurants nationwide and diners with an ever-growing selection of independent restaurants. Our demand network provides diners with the ability to order where they’re already online, including Google, Yelp, Instagram, Snap, and many others.  And our white-labeled online ordering system provides restaurants with a branded experience for diners on their website and their own iOS and Android apps for a reasonable monthly fee regardless of order volume. To date, we’ve created over 20,000 apps for our restaurant partners – something that’s never been done before in our category. We operate this way because of our belief in being fair, sustainable, and equitable with our restaurant partners and the same goes for our culture.

Diversity, teamwork, and mutual respect are among our core company values. We pride ourselves on giving our teams plenty of opportunities to make their mark. As we expand to new markets, while scaling responsibly, those opportunities to create, build, and grow will only increase. 

Join us and help ensure ChowNow becomes the diner’s first choice for socially responsible online ordering. Together we can preserve neighborhood flavor, one restaurant at a time. 

Our Product and Technology

Our backend applications are written in Python 3. The RESTful APIs we develop enable several client-facing platforms, ranging from our website products built with React & Redux to our native mobile applications. Depending on our use case, we store data in MySQL, Elasticsearch or Redis.

Our infrastructure-as-code platform is hosted by Amazon Web Services, developed and orchestrated using Ansible and Terraform. We automate as much as we can, utilizing Jenkins for deployments.
