Title and Summary
Principal Software Architect
Overview
We are seeking a Principal Software Architect to serve as a senior individual contributor and cross-organizational technical leader. This role is designed for an architect who leads through influence, consensus-building, and technical judgment, shaping architectural direction across many teams and stakeholders.
As a Principal Architect, you will operate across organizational boundaries, partnering with engineers, engineering leaders, product managers, and senior leadership to address the most complex and consequential technical challenges. You will not manage people directly, but you will mentor senior engineers, guide architectural decisions, and help align the organization around coherent technical direction.
This role is inherently collaborative: success depends on the ability to gather input, build shared understanding, and drive alignment among teams with different goals, constraints, and perspectives.
Key Role
Architectural Leadership & Strategy• Shape and evolve architectural direction across multiple teams and systems through consensus-driven decision making• Identify cross-cutting architectural concerns and guide teams toward shared patterns, principles, and solutions• Evaluate trade-offs between short-term delivery and long-term system health, articulating risks and options clearly• Help the organization converge on architectures that are scalable, resilient, secure, and operationally sound
Cross-Functional Influence• Act as a trusted technical partner to engineers, engineering managers, product leaders, and senior leadership• Facilitate architectural discussions that bring together diverse viewpoints and constraints• Translate complex technical concepts into clear, actionable guidance for both technical and non-technical audiences• Build strong working relationships across teams to enable alignment without formal authority• Hands-On Technical Contribution• Contribute directly to the most complex and high-impact technical problems (approximately 10-20% hands-on)• Lead design spikes, proof-of-concept efforts, and deep technical investigations where clarity is needed• Participate in design and code reviews for critical initiatives to ensure architectural intent is preserved• Support teams during difficult implementation or scaling challenges
Mentorship & Technical Excellence• Mentor senior engineers and emerging technical leaders across the organization• Raise the quality of engineering through example, coaching, and thoughtful feedback• Promote strong engineering practices in system design, testing, documentation, and operational readiness• Contribute to a culture of technical rigor, collaboration, and continuous improvement
All About You• 10+ years of professional software engineering experience• Proven experience operating at a principal or senior architecture level across multiple teams• Strong track record designing and evolving complex, distributed systems• Deep understanding of modern software architecture patterns (e.g., service-oriented, event-driven, API-centric systems)• Experience with cloud-native architectures and production concerns such as reliability, scalability, observability, and security• Demonstrated ability to influence technical direction through collaboration and consensus rather than authority• Excellent communication skills, including comfort engaging with senior leadership
Preferred Qualifications• Experience working in platform, shared-services, or foundational infrastructure contexts• Background in environments with high scale, high availability, or meaningful regulatory constraints• Experience helping organizations converge on architectural standards while preserving team autonomy• A reputation for sound judgment and pragmatic decision-making under ambiguity
What Success Looks Like• Architectural decisions improve in quality and consistency across teams• Teams align more quickly on shared approaches without feeling constrained• Complex initiatives encounter fewer late-stage architectural surprises• Senior engineers and leaders proactively seek out your perspective• Over time, the system becomes easier to evolve, scale, and operate
Why This Role Is Different• This is not a role for someone who relies on formal authority or mandates architecture from above.• It is for an architect who builds trust through technical depth and judgment, values collaboration and shared ownership, is comfortable working through ambiguity and disagreement, and knows when to go deep technically and when to step back and align people.
