Company mission
Teller's mission is to provide your app with beautiful account enrollment screens that send all sensitive data directly to their secure servers.
Role
Who you are
- You have a more sophisticated answer than "MITMProxy" for the question "How would you reverse a banking app's API contract?
- You thrive in environments that afford you with high levels of responsibility and autonomy
- You hold yourself and those you work with to high standards
- You want to fulfil your potential to its fullest, grow as an engineer to be the best you that you can be
- You don’t look for excuses for why something can’t be done, you are the person who finds the way it can be done
- If a skill that you don’t possess is required to complete a task you’re the kind of person who goes off and learns enough to get it done
- You behave like an owner. You take total responsibility for what you work on and think of the bigger picture like a product manager would
- You are results oriented and have a strong distaste for shaving yaks
- You are a persuasive communicator. You are both succinct and direct. You are clear about what you are doing, why, and what you expect of others
- You have strong opinions, weakly held, and the humility to change your mind according to the evidence as it presents itself
- You have experience of reverse engineering mobile applications
- You live and work in a timezone compatible with US/UK working hours
What the job involves
- We're looking for experienced reverse engineers to help us crack open mobile banking applications so that we can continue to add bank integrations to our API
Otta's take
Sam Franklin
CEO of Otta
Teller is a fully transactional banking API for your existing bank account. Their API enables developers to build applications that connect with their users’ bank accounts in a manner that is many more times reliable, predictable, performant, and fair than anything else available.
This seems like something that should be a solved problem in the present but before Teller, the state of the art was to rely on antiquated techniques such as screen-scraping online banking HTML pages. Of course, these pages were never designed for this so it’s no surprise that anything using this approach is hopelessly broken.
Banks do have real APIs. Externally facing APIs are necessary for their own apps to work, they would just rather you don’t have access to them. Teller aims to reverse engineer these apps to discover their secret API contracts and then implement clients for them. Teller's approach has enabled it to deliver a solution that is a 100x improvement and has led to promising early funding between 2020 and 2022.
