Automation and Scripting

We evaluate your ability to reduce manual toil through effective automation. Strong performance here involves demonstrating a mastery of scripting languages and a deep understanding of automation best practices.

Be ready to go over:

• Proficiency in Python, PowerShell, or Bash for system automation.
• Strategies for automating repetitive infrastructure tasks.

• Strategies for managing hybrid-cloud or multi-cloud environments.
• Advanced concepts: Disaster recovery planning, cost optimization at scale, and global load balancing.

As a DevOps and Tools Engineer, your primary objective is to empower the development team by creating frictionless pathways for code delivery. You will spend your day managing CI/CD pipelines, configuring monitoring tools, and collaborating with developers to optimize their workflows.

You will often find yourself acting as a technical consultant for various product teams, helping them integrate their services into the broader infrastructure ecosystem. This role is highly project-based, meaning you will frequently own initiatives from conception through to deployment, ensuring that every solution is documented, scalable, and secure.

We seek candidates who are not only technically proficient but also possess the maturity to handle the responsibilities of working in a high-stakes financial environment.

• Must-have skills: Expertise in CI/CD tools, containerization (Docker/Kubernetes), IaC (Terraform/CloudFormation), and strong scripting capabilities in Python or similar languages.
• Nice-to-have skills: Experience with security automation (DevSecOps), database administration basics, and familiarity with cloud-native monitoring stacks (Prometheus/Grafana).
• Professional background: A proven track record of improving system reliability and developer productivity in a professional, team-oriented setting.

Q: How long does the interview process typically take? The process duration can vary based on scheduling, but most candidates move through the stages within a few weeks. We prioritize quality and thoroughness, so ensure you have sufficient time to prepare between rounds.

Q: What differentiates successful candidates? Successful candidates are those who demonstrate a high degree of ownership, clear communication skills, and a genuine curiosity about how their work impacts the firm’s broader financial goals.

Q: What is the culture like? The culture is intellectually rigorous and collaborative. We value data-backed decisions and encourage engineers to contribute ideas that improve our collective efficiency.

• Structure your answers: Use the STAR method (Situation, Task, Action, Result) to keep your behavioral answers focused and impactful.
• Understand the "Why": Don't just list the tools you’ve used; explain why you chose them over alternatives and what the business outcome was.
• Prepare for ambiguity: In technical rounds, you may be presented with an open-ended scenario. Ask clarifying questions to narrow the scope before proposing a solution.

The DevOps and Tools Engineer role at Fisher Investments offers a unique opportunity to influence the infrastructure that supports global financial operations. By mastering the balance between automation, security, and scalability, you will play a critical role in our ongoing success.
