Detections / Security - Senior Security Engineer

The team of c / side is a diverse mix of highly capable subject matter experts. We’re kind, but we mean business.

Since January 2024, c / side has raised $7.7 million in pre-seed funding from Uncork Ventures, Mantis Ventures, Scribble Ventures, Roar VC, Dan Scheinman, Jason Warner, Kathy Korevec, and many more. A team of handpicked, high-value-add investors invested in helping our company and team grow.

About the role:

This is a special and super important role for us: we are looking for an engineer with a deep interest in security to help us build new detection methods, monitor threats as they happen, and play around with our massive amount of data on script behaviors to prevent client-side attacks for our customers.

What you will do:

1. Keep an eye out for attacks around the world; we have a lot of data and monitor many websites. There is always a new attack method to be found. We want you to find it, develop a detection method, use existing attributes where possible, and ship it!
2. Review detections that happen with some of our existing in-house detections. Some may catch something we’ll want to narrow down on.
3. Proactively define detections for client-side behaviors that can be malicious and review this against our script data.
4. Use and build internal tools to detect never-before-seen attacks.

About you:

The fact that you are in a key position to stop bad actors from impacting unknowing individuals motivates you.

Finding the gap between the specification of client-side JS and how JS engines are built is a hobby project for you.

You've been playing with LLMs and would love to use AI in security detections.

You’ve participated in capture-the-flag events or regularly spend time doing white-hat hacking or bug bounties.

You’re self-managing and want to disrupt the client-side (and web) security market.

You have at least 3-5 years of prior work experience.

At c / side:

We’re constantly learning and developing better; we grow together.

We do not ship half projects, we do not sell snake oil, we don’t cut corners - out of respect for our team, our customers, and our community. We put a dent in the universe by building good products.

We believe in strong opinions loosely held. We’re passionate and we strive to build the best thing together.

C / side offers:

1. 2-3 offsites per year (this changes from time to time).
2. Generous work from home allowance.
3. Latest MacBook.
4. Stock options.
5. Market rate salary.
6. Take what you need PTO.
7. Fully remote, 4 hours overlap with UK working hours required.

Our team is invested in your long-term career development. If you want to talk at events, we’ll make that happen; if you want to learn how to build your own startup one day, we’ll offer you a front-line seat. C / side is built by folks like you.

We’re building a world-class security company, and we simply want the best people for the job. We do not select or discriminate based on formal educational background, age, skin tone, religion, national origin, sexual orientation, gender identity, disability status, marital status, veteran status… we’re welcoming all and celebrate equal opportunities.
