Job description

Our Values (This is important):
Many organizations have a dusty list of corporate values that no one ever follows. Kalepa is not one of those companies. Our values are designed to unlock the potential of our employees.

Success at Kalepa is bred from five core principles:

Hustle and Determination - We hire people who take full ownership of their craft and relentlessly pursue excellence with speed and determination. We choose the hard problems and do not give up. This is the foundation of how we work and how we win.
Deliver Customer Impact - We're obsessed with customer impact. Every feature, every line of code, every decision is measured against one question: does this help insurers make better decisions? If it doesn't drive speed, accuracy, or profitability for our customers, we don't build it.
Meritocracy - We're building something exceptional, and that requires exceptional people and ideas. We have a high bar but we reward excellence with rapid growth. If you're the best at what you do, you'll thrive here.
Transparency - We value honest, transparent communication over politics. We challenge ideas, not people. We say what needs to be said, even when it's hard. This is how we solve problems fast and find the truth.
Experiment Relentlessly - Many of the problems we face have never been solved before. We tackle them by testing quickly, measuring rigorously, and iterating until we find the path forward. Speed of learning is our advantage.

You'll be right at home if you:
Have 5+ years of software engineering experience, ideally with a track record of improving and polishing functionalities to bring premium user experience.
Embody hustle and grit, you're excellent at your craft and relentless in pursuing it.
Take full ownership of your work and drive projects to completion with minimal oversight.
Communicate proactively, surfacing blockers, asking the right questions, keeping stakeholders in the loop.
Thrive on experimentation: you're comfortable testing ideas, measuring results, and iterating quickly on problems no one has solved before.
Have strong fundamentals in system design, debugging, and problem-solving.
You have experience in a modern FE framework, preferably React.
Know Javascript, Typescript, or Python, though we're open to strong candidates from other OO backgrounds.
Have experience with serverless technologies (Lambda, EC2), asynchronous workflows, and cloud environments.
Are comfortable with relational databases, ideally PostgreSQL.
Bonus: experience with LLMs/generative AI, distributed systems.
