Full Job Description
Mission:

Define and execute the long-term technical vision for JobNimbus's payments ecosystem, architecting a world-class, multi-billion-dollar scale financial platform. As a Principal Engineer, you will champion the strategic evolution of our Stripe-powered infrastructure, driving technical excellence, ensuring flawless system reliability, and aligning engineering capability with broad business growth. You will serve as the premier technical authority, bridging the gap between complex financial engineering and company-wide strategic objectives.

What You'll Be Doing:

  • Set the Architectural Vision: Define the multi-year technical roadmap for JobNimbus's payments and billing platform, ensuring it is built to handle explosive transaction volume, high availability, and future fintech expansions.
  • Drive Strategic Stripe Integration: Architect and govern deeply integrated, enterprise-grade Stripe workflows encompassing complex subscription models, global invoicing, dynamic payment intents, and resilient webhook mesh networks.
  • Cross-Organizational Alignment: Partner as a peer with Product, Finance, and Executive leadership to translate business strategy into scalable technical realities, ensuring the payments domain seamlessly intersects with other core product verticals.
  • Deconstruct Radical Complexity: Attack the most ambiguous, high-risk systemic challenges facing the platform, breaking them down into elegant, decoupled architectural blueprints for engineering teams to execute.
  • Hands-on Technical Leadership: Write elegant, foundational code for critical system components, establish core framework patterns in C# and Node.js, and review critical designs to maintain pristine system integrity.
  • Mitigate Financial Risk: Institutionalize best practices around transactional idempotency, eventual consistency, distributed data integrity, and strict security compliance within financial contexts.
  • Raise the Technical Bar: Establish company-wide engineering standards for event-driven architectures, testing strategies, operational observability, and system performance.
  • Multiply Engineering Talent: Act as a dedicated mentor and sponsor to Staff and Senior engineers, fostering a culture of continuous learning, deep technical curiosity, and extreme ownership.
  • Leverage AI Acceleration: Champion the strategic adoption of AI-assisted development tools to optimize engineering velocity, automate repetitive patterns, and uplift code quality across the domain.

What Makes You the Hero for This Job:

  • 10+ years of software engineering experience with a proven track record of architecting, scaling, and operating high-throughput production systems at an enterprise level.
  • Deep, domain-level expertise in Stripe and modern payment infrastructures, with an intimate understanding of ledgering, money movement, complex subscription lifecycles, and financial reconciliation.
  • Battle-tested knowledge of distributed systems failures; you know exactly how networks fail, how distributed transactions break down, and how to architect self-healing, idempotent systems.
  • Mastery of backend technologies, specifically C# and/or Node.js, utilizing event-driven microservices and asynchronous architectures.
  • Proven organizational influencer; you have a track record of leading technical strategy across multiple teams and navigating ambiguous organizational or system boundaries with ease.
  • Expert-level understanding of data engineering in a transactional environment, including relational databases, NoSQL design, and high-performance caching (experience with Couchbase is a major plus).
  • Strong foundation in modern infrastructure and cloud ecosystems (AWS, Terraform, Infrastructure as Code) with an emphasis on zero-downtime deployments and high availability.
  • Champion of Observability; you believe if it isn't monitored, it doesn't exist. You have deep experience with advanced telemetry, tracing, and proactive alerting in financial systems.
  • Pragmatic visionary; you possess the rare ability to balance long-term architectural purity with immediate business delivery, managing technical debt as a strategic variable.

Superpowers:
  • Ownership. You own the outcomes, drive initiatives, and solve problems proactively. If you need direction and someone to hold your hand, this job is not for you.
  • Customer Obsessed. Everything we build should leave our customers saying, "Aw dip. This product is off the charts cool. Whoever wrote that code deserves a raise!"
  • Proactive Learning. You stay ahead of the curve, continuously learning and implementing cutting-edge technologies.
  • Team Commitment. You build, mentor, and lead a high-performance engineering team that delivers results together.
  • Self Awareness. You know your strengths, weaknesses, and how to surround yourself with the right talent to succeed.
