Serko is a cutting-edge tech platform in global business travel & expense technology. When you join Serko, you become part of a team of passionate travellers and technologists bringing people together, using the world's leading business travel marketplace. We are proud to be an equal opportunity employer, and we embrace the richness of diversity, showing up authentically to create a positive impact. There's an exciting road ahead of us, where travel needs real, impactful change.

With offices in New Zealand, Australia, North America, and China, we are thrilled to be expanding our global footprint, landing our new hub in Bengaluru, India. With a rapid growth plan in place, we're hiring people from different backgrounds, experiences, abilities, and perspectives to help us build a world-class team and product.

As a Principal Engineer in Serko.ai Experience department, you are a key technical leader across every pod, particularly at the application experience layer. You're trusted with high autonomy to own major initiatives end-to-end and make the daily technical calls that keep teams shipping fast. You tackle the complex, system-level challenges that span beyond a single pod—proactively strengthening our agentic delivery systems, shaping solution design, and bringing clarity to our hardest engineering problems.

Requirements

You work alongside fellow Principal Engineers and our Senior Principal Engineer, so that several major initiatives can move in parallel. You set a high technical bar, leading by example through the work you do, particularly at application experience layer, and staying hands-on enough to unblock others — shaping solutions early, guiding technical choices, and reviewing what gets built, so pods can take real ownership of their delivery.

What you'll do

• Own System-Level Scope: Set the technical bar for our agentic delivery systems, investing in harness engineering and automated quality guardrails that keep agentic loops safe, fast, and trustworthy at scale.
• Elevate Engineering Craft: Partner early on solution design, set shared quality standards, and mentor Staff/Senior Engineers so teams move fast without compromising quality, with particular focus on experience layer, where system capability meets customer and frontend delivery makes or breaks outcomes.
• Lead Agentic AI Adoption: Evaluate and integrate emerging AI capabilities, ensuring responsible, safe, and scalable implementation across our growing product surface.
• Coordinate Strategic Migrations: Lead cross-department service handovers and integrations, aligning engineering efforts across time zones and business units.
• Connect Tech to Business Strategy: Represent Serko.ai Experience in executive planning and roadmapping, ensuring engineering decisions support the bigger picture.

What you'll bring

• Modern Full-Stack & Front-End Craft: Deep technical strength in Next.js/React, TypeScript, and Tailwind, with a sharp eye for building accessible, high-craft, customer-facing applications end-to-end. Working fluency in Python is valued.
• End-to-End Ownership & Autonomous Leadership: Proven track record leading major technical initiatives, resolving cross-team dependencies across time zones, and making high-trust architectural decisions that keep teams moving fast.
• AI & Agentic Fluency: Solid understanding of AI and agentic capabilities, ensuring safe, scalable product adoption while actively using AI-assisted tools to multiply throughput for yourself and surrounding engineers.
• Systems Infrastructure & Platform Integration: Experience integrating shared platform services into live products and strengthening core developer infrastructure (CI/CD, test automation, dev environments) to elevate department-wide reliability and speed, alongside familiarity with Design Systems, component architecture, and responsive/accessible UI patterns.
• Collaborative Leadership & Mentorship: Exceptional communication skills with a history of mentoring across multiple teams, co-leading initiatives alongside peer Principals, and guiding solution design without taking over team ownership.
