Job description

We’re looking for a player-coach to lead infrastructure at Unstructured. This role is perfect for a Principal Infrastructure Software Engineer ready to mentor or a hands-on Director who still loves to build. You’ll own our cloud infrastructure and internal platforms, mentor engineers, and set the direction for how we scale securely and efficiently. As a key technical leader, you will own organization-level infrastructure design and reliability strategies, large-scale infrastructure challenges. Your work will be foundational to scaling our systems, ensuring high availability, performance, and security across our stack.

Key Responsibilities:

Infrastructure Leadership: Own and drive the architecture and design of scalable, resilient infrastructure systems across the organization. Define and influence infrastructure strategy in alignment with product and business goals.

Strategic Projects: Lead cross-functional, high-impact infrastructure initiatives involving compute, networking, storage, and orchestration. Provide deep technical guidance and mentorship across engineering, platform, and DevOps teams.

Systems Problem Solving: Solve persistent and complex infrastructure problems at scale. Drive root cause analysis, mitigation strategies, and proactive risk reduction across systems.

Hands-On Engineering: Contribute directly to the design, implementation, and optimization of core infrastructure. Improve CI/CD pipelines, observability, automation, and production readiness for mission-critical systems.

Mentorship & Enablement: Mentor engineers and promote a culture of operational excellence, automation, and reliability. Act as a force multiplier by raising infrastructure engineering standards and best practices across teams.

Cross-Team Alignment: Ensure consistent, simple, and scalable infrastructure designs that enable fast-moving product teams. Resolve escalations related to performance, uptime, or platform dependencies and prevent long-term architectural bottlenecks.

Organizational Impact: Shape how we build, deploy, and operate our systems now and in the future. Make foundational decisions that impact developer experience, cloud strategy, and platform capabilities.

Qualifications:

-Experience: 10+ years of infrastructure or site reliability engineering experience with a track record of leading and delivering complex systems at scale.

-Technical Expertise: Python, Deep knowledge of cloud platforms (e.g., AWS, GCP, or Azure), containerization (e.g., Docker, Kubernetes), IaC tools (e.g., Terraform), and system observability.

-Leadership: Proven experience influencing technical strategy and architecture across multiple teams. Skilled at mentoring and building high-performing infrastructure or SRE teams.

-Problem Solving: Exceptional systems-thinking and debugging skills; adept at analyzing complex distributed systems and designing scalable, fault-tolerant solutions.

-Communication: Clear, concise communicator who can convey infrastructure concepts to both technical stakeholders and non-engineering partners.

-Adaptability: Comfortable operating in ambiguous, fast-changing environments where infrastructure needs evolve rapidly alongside product requirements.
