Your mission
As a Senior Software Engineer at Intigriti, you are a trusted, autonomous technical expert at the heart of our engineering drive. Working closely with tech leads and architects you will be building high-impact features, evolving a scalable, reliable architecture, and mentoring others to level up.

Senior Engineers at Intigriti are expected to drive technical excellence and ensure our systems are secure for thousands of users in the cybersecurity community. We thrive as a crowd, and you will be key driver of success within our growing team.
What you’ll be doing
  • Owning features from beginning to end. Senior engineers are often put into a Feature Lead position. This means they collaborate directly with a Product Manager and a Product Designer to get a feature from possibility to reality. It means understanding the problem, designing a solution and getting it into production. This also means writing tickets, documentation and presenting the feature to the organization.
  • Going deep. Because of our unique architecture, you will encounter challenging technical problems. Whether it is related to performance, scalability or complexity, you’re expected to dive into a problem and come out the other end with a solution. This often means spending days reading documentation and running tests.
  • Support. Every week one senior member of the team is our designated Production Hero Of The Week. Their job is to monitor our production environment, act as the go-to engineer for critical incidents, and provide support to both internal teams and customers.
  • Collaborate and mentor. Senior Engineers are expected to communicate well both inside of a team as across teams. You’ll often have to collaborate with SREs on architecture or production incidents. Junior members of the team will look to you for guidance. You’ll have to mentor them through radically honest but constructive feedback, presenting best practices and sharing knowledge.
What you’ll bring
  • A drive to build stuff. You are passionate about building stuff and making an impact for your users. You don’t just focus on the code, you care about the bigger picture. You get excited about boldly exploring new ideas that might just help us move the needle.
  • A fix-it mentality. Problems don’t scare you. You know there’s a solution for everything, and you’re gonna find it. You don’t let a production issue go by unnoticed, instead you crack your knuckles and dig in.
  • Authenticity. You keep it real and give your opinion, especially if it goes against your peers or your manager.
  • Curiosity. You’re not content knowing something works, you want, no, need to know how it works. You never stop learning. ****
  • Security-minded. What we do at Intigriti keeps people secure and we care about that a lot, so it’s important that you care as well. You want to help us make security a top priority.
Requirements
  • 5 - 10+ years of professional software development experience.
  • Deep expertise in:
    • C# / .NET
    • Angular
    • AWS cloud components (RDS, EKS, ECS, CDK, …)
  • Solid understanding of the system architecture concepts we use daily:
    • CQRS
    • Service mesh (Istio)
    • Event-driven architecture
    • Distributed systems
  • Strong grasp of software design principles and maintainable system patterns.
  • Experience participating in and influencing technical roadmap decisions.
  • Strong communication skills, with the ability to explain technical issues to both technical and non-technical stakeholders.
  • Familiarity with monitoring, logging, CI/CD pipelines, IaC (e.g., AWS CDK), and general operational best practices.
  • Awareness of cybersecurity concepts and the bug bounty domain, or willingness to deepen expertise.
