Software Engineer (Expert)

Department: ⚒️ Engineering

Location: Paris

Employment Type: FullTime

🧭 About Konvu

At Konvu, we’re on a mission to make security invisible, redefining vulnerability management for the agentic world.

As AI begins to generate, test, and deploy code autonomously, legacy security approaches break down. Konvu’s AI agents reason like security engineers: automatically triaging noise, verifying exploitability with evidence, and helping teams focus on what truly matters.

Our agents plug directly into existing scanners and workflows, no rip-and-replace, no new dashboards. We deliver evidence-backed decisions where teams already work, cutting false positives and surfacing exploitable issues with confidence.

Founded by early members of Sqreen (YC W18, acquired by Datadog), we know what it takes to turn deep technical insight into tools developers and security teams actually use.

We’ve raised $5M in Seed funding and are backed by top European and US VCs, as well as leaders from companies like Datadog, GitHub, Docker, Cloudflare, Sumo Logic, and Vanta.

We’re looking for an expert-level Software Engineer to join us in Paris and play a crucial role in this journey.

🛠️ What you’ll do

You’ll help design, build, and operate systems that solve real vulnerability management problems for engineering and security teams, shaping both our technology and our user experience as we grow.

• Build product end-to-end. Design, implement, and ship features that deliver clear value to customers. You’ll work across the stack, from backend services and data flows to APIs and frontend experiences.

• Ship value fast. Balance thoughtful design with fast iteration. You’ll prototype, learn from real usage, and refine quickly so we can continuously improve the product.

• Take ownership. Own key product and technical decisions from idea to production. You’ll identify what needs to be done, break down complex problems, and drive them to completion. You’ll have space to focus, while collaborating closely with teammates across engineering, product, and design.

• Stay close to customers. Work with our users over Slack and on calls to understand how they use what you’ve built. Turn their feedback into concrete improvements and new features.

• Design robust architectures. Create systems that are clear, reliable, maintainable, and scalable. We care a lot about strong engineering fundamentals: good tests, clean abstractions, fast builds, and solid observability.

• Contribute beyond code. Help shape our technical culture, engineering practices, and product direction. As an early team member, your decisions will have a lasting impact on how we build.

👤 Who you are

Even if you don’t meet every qualification, we encourage you to apply if you’re driven to create real impact.

• 6+ years of experience as a software or product engineer, ideally with significant time in startup or fast-paced environments.

• Proven ability to build impactful products that address real-world customer needs.

• Strong engineering fundamentals: you care about code quality, architecture, testing, and operational excellence just as much as you care about shipping.

• Product-minded mindset: you think about the “why” behind what you’re building and are comfortable making trade-offs between scope, quality, and speed.

• Intellectual curiosity and drive to build. You like digging into problems, learning new domains, and seeing things through.

• Positive attitude toward AI and excitement about its potential to transform security and engineering.

• Excellent communication in English (our working language).

• Eagerness to work onsite from our Paris office.

Nice-to-have (not required):

• Experience building developer, infrastructure or security tools

• Exposure to agentic systems

🧪 Our hiring process

• 30-minute video call with our CEO

• 1-hour video call with our CTO

• Take-home exercise

• Onsite interview with the team: 2 hours total

• Reference calls

💎 Why Work at Konvu

We’re building AI agents that redefine how security and engineering teams work. We’re assembling a world-class team of builders who want to push what’s possible in security and AI.

Here is what it's like to be working here

• Startup principles in action: we’re shaped by YC principles, which means fast iteration, ownership from day one, and solving problems that matter. Whether you’re shipping features or closing customers, you’ll actually see your impact every week.

• Globally minded from day one: Konvu was built from both sides of the Atlantic, combining European engineering excellence with American ambition. Our goal is simple: build a product loved by security and engineering teams, wherever they are.

• A culture of sharing and learning: People here don’t just build or sell, they also teach and grow. From technical deep dives and sales playbook reviews to speaking at events like our Konvupéro meetups or industry events, you’ll have space to grow and contribute beyond your core role.

• Hard, meaningful problems: You’ll work on AI agents that reason about exploitability and risk and run reliably inside complex enterprise environments, and help customers turn that into real-world outcomes. It’s the kind of work that pushes your limits and makes you proud of what you’re building.

• Strong upside: We offer a competitive salary, meaningful equity, and comprehensive benefits so you can grow with the company you’re helping build.

💜 Our commitment to diversity

At Konvu, we deeply value diversity and are dedicated to fostering an environment where everyone feels supported and can thrive. To build a product that’s loved by everyone, we need a team with all kinds of different perspectives, experiences, and backgrounds. This is why we are committed to hiring people from all walks of life.
