Email Security Engineer information

What does an email security engineer do?

An Email Security Engineer is responsible for protecting an organization's email systems from threats like phishing, malware, and spam. They design, implement, and manage security protocols and tools to detect and prevent unauthorized access or data breaches via email. Their role often includes monitoring email traffic, responding to security incidents, and educating staff on safe email practices. They also stay updated on the latest email security trends and technologies to ensure ongoing protection.

What are some common challenges faced by email security engineers when implementing new security protocols across an organization?

Email Security Engineers often encounter challenges such as balancing robust security measures with user convenience and maintaining compatibility with existing systems. Rolling out new protocols may require coordinating with IT, compliance, and end users to ensure minimal business disruption. Additionally, staying ahead of evolving phishing and malware tactics demands continuous monitoring and updating of filters and policies. Effective communication and training are also crucial to ensure staff understand and adhere to new security practices.

What are the key skills and qualifications needed to thrive as an email security engineer, and why are they important?

To thrive as an Email Security Engineer, you need a strong understanding of email protocols, cybersecurity principles, and threat analysis, often backed by a degree in computer science or a related field. Proficiency with email security tools like Proofpoint, Mimecast, or Microsoft Defender, and certifications such as CEH or CISSP, are commonly required. Analytical thinking, attention to detail, and strong communication skills help professionals identify threats and educate users effectively. These competencies are crucial for protecting organizations against evolving email threats and ensuring secure, uninterrupted business communications.

Job description

About Fluidstack
We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.
We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.
We hire people who care deeply about this problem space. If that is you, please apply!
How We Operate
  • Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
  • Velocity. We drive everything forward as fast as possible.
  • First principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
  • Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.
The Security Team
Examples of key problems the team is working on
  • You're securing the frontier of AI. The model weights training on our infrastructure are the most valuable and most targeted artifacts in technology, and we're standing up the compute to hold them faster than anyone ever has. A breach isn't a leak, it's the frontier walking out the door.
  • Build the entire security program from scratch. Most leaders inherit someone else's system and spend a career patching it. Here you own it end to end, bare metal to boardroom, as we scale across continents.
  • Your threat surface is measured in gigawatts. The customers running on our infrastructure are building the most consequential technology in human history, and being responsible for the physical and logical security of that work makes everything else feel small.
Role Scope
  • Own security for the cloud and bare-metal control planes customers' training runs depend on: hardening, identity, and workload isolation.
  • Build guardrails as code: policies, scanning, and paved roads that make the secure path the fast path for engineers.
  • Engineer detection and response across cloud infrastructure, from API abuse to compromised credentials to tenant escape.
  • Secure the multi-tenant boundary where customer workloads, some of the most targeted in AI, share infrastructure.
What We're Looking For
  • The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
  • You've secured production cloud or bare-metal infrastructure hands-on, not just audited it.
  • You've shipped security tooling engineers actually adopted.
  • You've found and fixed real isolation or privilege-escalation issues.
  • You write production-quality code and treat policies as software.
  • You've run incident response on infrastructure you helped build.
  • Bonus: Kubernetes and container security. Hardware root of trust and measured boot. eBPF-based detection. GPU and HPC environments.

We are committed to pay equity and transparency.
Fluidstack is an Equal Employment Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, sexual orientation, gender identity, disability and protected veterans' status, or any other characteristic protected by law. Fluidstack will consider for employment qualified applicants with arrest and conviction records pursuant to applicable law.
You will receive a confirmation email once your application has successfully been accepted. If there is an error with your submission and you did not receive a confirmation email, please email careers@fluidstack.io with your resume/CV, the role you've applied for, and the date you submitted your application-- someone from our recruiting team will be in touch.
