What is a Security Engineer at AlphaSense?

As a Security Engineer at AlphaSense, you are the guardian of a platform that the world’s most sophisticated companies rely on for critical decision-making. Our clients—including the majority of the S&P 500—trust us with sensitive search data, proprietary content, and market intelligence. Your role is to ensure that this trust is never compromised while enabling our engineering teams to move fast and innovate.

In this role, you are not just a compliance officer; you are an engineer first. You will be part of the Cloud Security Team, a group with significant independence to plan, drive, and develop security improvements. You will work directly with our cloud environments (primarily AWS), containerized infrastructure (Kubernetes), and Infrastructure as Code (IaC) pipelines. Your impact is tangible: you will build the automated controls, detection mechanisms, and secure architectures that protect our AI-driven market intelligence platform from evolving threats.

Getting Ready for Your Interviews

Preparation is key. At AlphaSense, we look for "hands-on security leaders"—engineers who can think strategically about risk but also dive deep into the code and infrastructure to fix it.

Here are the key evaluation criteria you must demonstrate:

Technical Depth in Cloud & Containers – You must demonstrate expert-level knowledge of AWS and Kubernetes. We don't just want to know if you can use a tool; we need to know if you understand the underlying security primitives of containerized environments and how to secure them at scale.

Automation & Coding Proficiency – We operate with a DevOps mindset. You will be evaluated on your ability to write code (e.g., Python, Go) to automate security controls and integrate security into CI/CD pipelines. Manual security reviews are not scalable here; you must show an "automate-first" mentality.

Architectural Problem Solving – You will face ambiguous scenarios where you must design secure solutions for complex problems. We evaluate how you balance security requirements with engineering velocity and product functionality.

Ownership & Autonomy – The Cloud Security Team has strong independence. We look for candidates who can identify a problem, own the solution from design to implementation, and collaborate cross-functionally without needing constant oversight.

Interview Process Overview

The interview process for the Security Engineer role is rigorous and designed to test both your practical engineering skills and your security mindset. Expect a process that moves from high-level fit to deep technical validation.

Typically, the process begins with a recruiter screen to align on your background and interest. This is followed by a hiring manager screen, which digs into your specific experience with cloud security and Kubernetes. If successful, you will move to the technical rounds. These stages often involve practical assessments—expect to read code, discuss architecture, or solve a scripting challenge. You will likely face a mix of "design a secure system" scenarios and specific "how would you mitigate this vulnerability" questions.

The final stage is a series of onsite (or virtual onsite) interviews. These cover a broad range of topics including threat modeling, behavioral questions focused on cross-team collaboration, and deep dives into your past projects. We value engineers who can explain the why behind their decisions, not just the how.

The timeline above represents a typical flow, though specific steps may vary slightly depending on the team's immediate needs. Use this to gauge your energy; the technical deep dives and onsite rounds require the most intensive preparation.

Deep Dive into Evaluation Areas

To succeed, you need to demonstrate expertise across several core domains. We rely heavily on your ability to secure modern, containerized infrastructure.

Cloud Infrastructure Security (AWS)

You must be comfortable securing large-scale AWS environments. We look for deep understanding, not just surface-level familiarity. Be ready to go over:

• IAM & Least Privilege: Designing robust IAM policies, roles, and cross-account access models.
• Network Security: VPC design, Security Groups, NACLs, and transit gateways.
• Infrastructure as Code (IaC): Securing Terraform or CloudFormation scripts and detecting misconfigurations before deployment.
• Advanced concepts: AWS Organizations, SCPs, and automated remediation using Lambda.

Example questions or scenarios:

• "How would you automate the detection and remediation of open S3 buckets across hundreds of accounts?"
• "Walk me through how you secure a multi-account AWS architecture."

Kubernetes & Container Security

This is a critical requirement for the Senior Cloud Security Engineer role. You need 4+ years of hands-on experience here. Be ready to go over:

• Pod Security: Pod Security Standards, admission controllers (e.g., OPA Gatekeeper, Kyverno).
• Runtime Security: Detecting anomalies in running containers (e.g., Falco).
• Supply Chain Security: Image scanning, signing, and securing the registry.
• Advanced concepts: Kernel isolation, CNI security, and service mesh (Istio/Linkerd) security.

Example questions or scenarios:

• "How do you prevent a compromised container from accessing the underlying host node?"
• "Explain how you would implement network policies in a Kubernetes cluster to isolate sensitive workloads."

Application Security & DevSecOps

We expect you to integrate security into the development lifecycle. Be ready to go over:

• CI/CD Integration: Inserting SAST, DAST, and SCA tools into pipelines (Jenkins, GitHub Actions, etc.).
• Vulnerability Management: Prioritizing and remediating vulnerabilities in code and dependencies.
• Threat Modeling: Analyzing architectural diagrams to identify risks (STRIDE, DREAD).

Example questions or scenarios:

• "How do you handle a critical zero-day vulnerability found in a library used by 50 different microservices?"
• "Design a secure CI/CD pipeline that prevents developers from pushing secrets to the repository."

Key Responsibilities

As a Security Engineer at AlphaSense, your daily work will blend strategic planning with hands-on engineering. You will be responsible for developing and automating security controls for our cloud infrastructure. This means writing the code that enforces security policies rather than manually checking configurations.

You will maintain, integrate, and scale cloud security tooling. Whether it's a CSPM (Cloud Security Posture Management) tool or a custom vulnerability scanner, you own the health and efficacy of these systems. When incidents occur, you will partner with incident response teams to investigate and mitigate security incidents, often building the detection logic that alerts us to suspicious activity in the first place.

Collaboration is essential. You will conduct architecture reviews and threat modeling sessions with product engineering teams, helping them design secure features from the start. You will also work with compliance teams to translate frameworks like ISO 27001 and SOC 2 into technical controls, ensuring we meet our obligations without slowing down development.

Role Requirements & Qualifications

We are looking for seasoned professionals who can hit the ground running.

• Must-have Technical Skills:

  • 8+ years of total experience in cloud security.
  • 4+ years of hands-on experience specifically with containerized environments (Docker, Kubernetes).
  • Deep expertise in AWS security services and architecture.
  • Proficiency in at least one programming language (e.g., Python, Go) for automation.
  • Strong grasp of Infrastructure as Code (IaC) tools like Terraform.

• Soft Skills & Culture:
