Senior Software Engineer, Security Infrastructure
Parafin
About the Position
We're seeking an experienced software engineer to join our Infrastructure team to lead key initiatives around security-focused platform engineering. At Parafin, the Infrastructure team owns core platforms spanning cloud infrastructure, compute, networking, developer experience, data infrastructure, and security.
In this role, you'll design and implement scalable, secure systems and tooling that empower engineers to move quickly while maintaining a strong security posture. You'll play a critical role in shaping how we manage access, secure our compute and networking layers, and build foundational infrastructure that supports our rapidly growing platform.
What You'll Be Doing
Lead the design and implementation of secure, reliable infrastructure platforms—across compute, networking, identity, and policy enforcement.
Own and evolve the security posture of our Kubernetes platform, focusing on isolation, observability, and resilience.
Build and operate systems for managing secrets, service-to-service auth, and access control.
Define and codify best practices in infrastructure security, infrastructure-as-code, and software integrity.
Collaborate with engineers across Infrastructure and Product teams to introduce secure-by-default tooling and abstractions.
Drive improvements to our availability, incident response, and audit capabilities through automation and thoughtful platform design.
Mentor engineers and influence a culture of security-minded engineering across the company.
What We're Searching For
5+ years of experience in software or infrastructure engineering, with significant focus on secure infrastructure and platform development.
Strong proficiency in coding languages such as Python
Deep expertise with Kubernetes and its surrounding ecosystem (e.g., service mesh, admission controllers, observability, RBAC).
Experience operating cloud infrastructure (preferably AWS), including IAM, VPCs, and secure configuration management.
Proficiency with infrastructure-as-code tools such as Terraform.
Familiarity with secrets management (e.g., Vault), CI/CD hardening, and runtime/container security practices.
Strong problem-solving and debugging skills in distributed systems.
Excellent communication skills and experience collaborating with cross-functional teams.
We Prefer If You Have
Experience building or maturing security infrastructure in a fast-paced or regulated environment.
Understanding of compliance requirements in fintech (e.g., SOC 2, PCI) and how to build guardrails that support them.
A track record of building internal tools or reusable platform abstractions adopted by multiple teams.
