Founding Engineer

About the role
We are looking for a founding engineer to fold time and help us reach every practice in the country.

Some things you will be working on
Automate customization and onboarding
To build a 5-person unicorn, we have to automate more than just calls.
How can we cut down onboarding time from days to minutes? How can we enable doctors to easily customize their receptionist on their own?
Optimize scheduling to increase a practice’s revenue
Dental scheduling is more complicated than finding the soonest availability. Procedures have different costs and durations, some require more than one provider, others can be double booked…etc.
How can we create an optimal schedule every day for our practices that grows their revenue while still allowing them to provide a high level of care?
Low latency at scale
If the agent takes more than 1s to respond, callers get frustrated and hang up. How can we scale to 100K+ calls a day without sacrificing reliability or speed?
Accents, dialects, and languages…
All of the above needs to work in every accent, dialect, and language.
Who we are looking for
Someone who can write code, prompts, Terraform configs, emails, and everything in between.

We handle phone calls non-stop for at least 12 hours a day, and there is almost no margin for error. If we drop a call, a practice loses revenue. We thrive under pressure and you should too.

Debt Collectors play an overlooked yet integral part of our financial ecosystem. They help Consumers settle their debts and improve their credit scores— granting them clean states to start over. Collectors help critical businesses like doctor's offices and local governments, who deal with high payment default risk, secure their revenue streams and ensure their continued survival.

In truth, Collectors have incredibly interesting, multi-faceted jobs. They are often one part sales person, one part therapist, and one part detective in their mission to recover funds. At Aktos, we are building a modern software platform that caters to Collectors' unique workflows, and make the credit recovery process a more positive experience for all parties.
