Job Summary
We are seeking a Principal Engineer Software to lead the technical evolution of our Identity Governance & Administration (IGA) platform. This is a role for a deeply technical, hands-on engineer who thrives on solving the "hard problems" and setting the pace for the team. You will be a primary driver of our codebase, delivering high-impact features while ensuring our architecture remains secure, observable, and performant. As a senior technical presence, you will naturally uplevel the engineers around you by demonstrating engineering excellence in practice—shaping the platform through superior code, insightful design reviews, and the practical application of engineering standards.
What You’ll Do
Drive End-to-End Initiatives: Lead technical initiatives across Identity Governance & Administration (IGA), from problem discovery and design through implementation, rollout, and long-term ownership.
Lead AI-First Engineering Practices: Apply high AI tool fluency and prompt/context engineering to design AI-assisted workflows across the agentic SDLC. Rigorously evaluate AI-generated code to prevent hallucinations, security gaps, and logic defects.
Execute with Autonomy: Operate with a high degree of autonomy, translating ambiguous business and product problems into well-designed technical solutions.
Define and Govern Standards: Establish engineering benchmarks to enhance the testability, observability, and performance of all technical solutions.
Architect Complex Systems: Design cross-functional architectures that effectively balance product requirements with rigorous security constraints.
Mentor and Uplevel Teams: Lead design reviews and architecture discussions while coaching engineers on implementation, testing, and security best practices.
Drive Strategic Alignment: Build trust through clear communication and lightweight RFCs, collaborating with product partners to influence outcomes without formal authority.

Qualifications
Full-Stack Technical Expertise: 10+ years extensive experience with the MEAN stack (MongoDB, Express, Angular, Node.js) and modernizing legacy frameworks.
Cloud Architecture & Infrastructure: Proven track record in cloud engineering environments, with a primary focus on AWS ecosystems.
Systems-Level Thinking: Ability to reason across complex layers—including APIs, identity, and observability—to make technical trade-offs explicit and decisions durable.
AI Tooling & Output Verification: Expertise in prompt and context engineering, utilizing AI tools within software development while exercising peer-review rigor to verify AI outputs for correctness and security.
Security-First Mindset: Deep practical knowledge of secure web development, including OWASP Top 10 mitigation, Zero Trust principles, and Least Privilege access.
Collaborative Leadership: Strong communicator skilled at facilitating cross-team design sessions, mentoring and “leveling up” more junior engineers, and driving consensus across stakeholders.
Operational Excellence: Committed to building highly observable and performant systems by integrating testing and monitoring into the core development lifecycle.
Nice to Have
Security & Identity Specialization: Working knowledge of Identity & Access Management (IAM), PAM, IGA, and robust secrets management for security-centric products.
Design Systems at Scale: Experience managing cross-product component governance and maintaining unified design languages across large-scale applications.
Modern DevOps Practices: Familiarity with observability tools, feature flagging strategies, and implementing progressive delivery within CI/CD pipelines.
Performance & Scalability: Proficiency in load and stress testing using tools like JMeter to ensure system resilience and identify architectural bottlenecks before production.
Data Privacy & Compliance: Familiarity with privacy-by-design principles and technical implementations for GDPR, CCPA, or SOC2 compliance, particularly regarding data anonymization and auditability.
Advanced Frontend Tooling: Fluency in TypeScript, RxJS, and Signals, complemented by modern testing frameworks like Jest, Playwright, or Cypress.
Impact
You will be a cornerstone of the technical foundation and engineering culture behind our flagship IGA experience. By leading from the codebase, you will transform ambitious product visions into high-performance, secure realities that our customers trust. Your influence will be felt through the durability of the systems you build and the rising caliber of the engineers you work alongside. Ultimately, you will bridge the gap between legacy challenges and modern solutions, creating a maintainable, enterprise-grade platform that empowers our teams to ship with confidence and speed.
Excellent written, verbal, and cross-functional communication skills, especially when working with product, design, and non-engineering stakeholders.
Bachelor’s degree in computer science or a related field, or equivalent practical experience.
Ability to work a hybrid schedule in the Newton, MA area.
