At SIG, we know the job market for Information Security is incredibly tight.  So, why work with us?  In short, our Security Engineering team will inspire and challenge you, sharing their diverse backgrounds and deep knowledge and will look for you to do the same. Our approach to security is proactive and driven by risk and value to our business.  We are challenged with not only ensuring the security of our solutions but doing so effectively and efficiently to maintain SIG’s competitive business advantage.


The opportunities we offer provide freedom to innovate & to stretch beyond designing simply to meet pre-existing regulations or specifications. Rather, you’ll have the opportunity to develop forward thinking ideas and design solutions that push the technologies and security products you’re working with (or building from scratch) farther than they might have been initially designed for.  You’ll drive these solutions & manage them end to end, partnering with teams within and outside of technology to address business needs.  You’ll be able to think out of the box, developing and implementing your ideas in a global environment, ensuring their scalability & providing support as issues arise or business needs change.  Interested in engineering technological security defenses for a highly complex corporate environment?  We want to talk!
