About Smarter Technologies

Smarter Technologies is transforming healthcare technology through innovative automation, AI-driven workflows, and a commitment to improving outcomes for providers. With deep expertise across health tech and a rapidly expanding footprint, we’re scaling fast and looking for engineers who can help keep our systems and data safe.

Role Overview

We’re seeking experienced security engineers who can design secure systems, implement those ideas in code, and work seamlessly with engineering teams to solve problems across the stack, one pull request at a time.

You might be a security engineer, a penetration tester, or a software engineer. Regardless of your title, we’re looking for people with a strong foundation in software and network fundamentals, deep security expertise, and experience working with developers in a shared codebase. The ideal candidate can set high standards while executing efficiently in a fast-growing startup environment.

If you enjoy solving problems across AppSec, CloudSec, and NetSec and writing the code to make those solutions real, then this role is for you.

Primary tech stack: Python, TypeScript, Terraform, AWS, and Kubernetes.

Key Responsibilities

  • Partner with engineering and product teams to deliver practical, high-impact security outcomes that improve reliability and developer velocity.
  • Design, implement, and maintain security controls across applications, infrastructure, and networks.
  • Contribute and review code in our internal Git repositories for customer-facing applications, APIs, internal tools, and automation.
  • Identify and mitigate security gaps in AWS, Kubernetes, and other cloud environments.
  • Work with stakeholders to harden 3rd party cloud service integrations and configurations (e.g. Snowflake).
  • Participate in incident response and building SIEM detections as code.

What Success Looks Like

  • Engineers see you as a trusted peer who helps them ship faster and safer.
  • Security controls become more defined, repeatable, and streamlined.
  • Security gaps are identified, prioritized, and remediated through code and automation.
  • Progress can be objectively measured with metrics.
  • Security becomes an enabler of innovation, not a bottleneck.

Minimum Qualifications

  • 5 years of experience in security engineering, product security, or software engineering with a security focus.
  • Solid understanding of application, infrastructure, and network security fundamentals.
  • Hands-on experience with AWS and Kubernetes in production environments.
  • Ability to write and maintain production-quality code in at least one modern language.
  • Experience working collaboratively with developers in shared codebases using Git-driven workflows (e.g., pull requests).
  • Comfortable working independently and taking ownership in a fast-paced, high-autonomy environment.
  • Excellent communication skills and ability to collaborate across technical and business teams.

Bonus Points

  • Python and Terraform development experience.
  • Familiarity with GCP or Azure.
  • A background in software engineering or penetration testing.
  • Hands-on threat detection and incident response experience.
  • Experience working for startups.
  • Experience in regulated industries with compliance requirements (e.g., SOC 2, HIPAA, HITRUST, PCI, ISO).

  • Equity participation: Employee Stock
  • Health benefits: Comprehensive medical, dental, and vision insurance
  • Time off: Generous leave policies and paid company holidays
