Job Specifications

Trickle is the voice-enabled Executive Assistant you've been waiting for, and we're looking for developers to support our growth!

We're looking for a hands-on SENIOR Full Stack Developer that vibes with the Startup Life!

Tasks

You’ll be bridging the gap between our product vision, evolving market needs, and the technical foundation of our platform. Picture yourself exploring cutting-edge web and mobile technologies, experimenting with ML-driven features, and building something that the world has never seen before.

We're a deeply innovative startup so we're pretty much looking for someone who has the right mindset - yes, that means we expect more than a 9 to 5 mentality, we might even work on weekends, but... you'll never find a bunch of people or a job like this anywhere else. We offer TONS of flexibility, we go on (actually fun) team dates every quarter, our CEO might just randomly decide to host a BBQ, we might crack dirty jokes all day, we'll drink whiskey at the office to celebrate a milestone, or we'll just go out for drinks if the mood is right.

We're serious about this; we work hard and play hard, if that's not your vibe, kindly move on.

Think of this position as your gateway to shaping not just code, but also product direction and eventually growing into a future executive or leading tech role within the team - either in Full Stack Development or ... whatever... if you like it, are (looking to get) skilled in it, and it supports Trickle's growth, then we'll help you get there!

Requirements

Our offer

A competitive salary with significant growth potential and a commitment to exceed market value as we grow

A hybrid work environment - office, home, or anywhere you need to be

Be part of a stellar team and create your own career path

Become a co-owner of Trickle (ESOP plan)

A chance at hands-on training from one of the greatest minds of this generation - or at least, you know, a pretty good one. Decent, really.

A BBQ as a signing bonus

Must haves

A startup life mentality! If that's not your thing, don't bother applying.

Hands-on experience building full stack applications (front-end, back-end, maybe even some DevOps thrown in)

An interest in Artificial Intelligence and Machine Learning

A winner's mentality: willingness to do whatever it takes to get the job done!

A can-do attitude that focuses on solutions and not complaints

Some basic visual/design chops are highly appreciated

A (weird?) sense of humor - this is really important

Oh, you live somewhere that's actually reasonably close to the Corda Campus in Hasselt - you do have to show up to the office every now and then

Deep knowledge of dotnet and front-end frameworks (Flutter ideally but React would be sufficient).

Nice to haves

A bachelor or master degree in computer science

A basic knowledge of Artificial Intelligence

We're hiring on an employee basis, no freelancers at this time

We won't hire anyone that uses an intermediary agency to find a job - lazy much?
