Department: Technology - Serko.ai
At Serko, we believe something incredible happens when people come face-to-face. That’s why we’re on a mission to engineer a frictionless, next-generation business travel marketplace. We don’t just manage travel; we are leveraging advanced AI and cutting-edge tech to eliminate the complexity of global movement.
When you join Serko, you join a global collective of passionate technologists who show up as their true selves to build world-class products. With established hubs across New Zealand, Australia, North America, India and China - your code and ideas will impact millions of corporate travelers worldwide.
If you're ready to challenge the status quo and build the future of travel tech, your next journey starts here.
Reporting to a Senior Engineering Manager or Engineering Manager, you lead the design and delivery of moderately complex solutions at the application experience layer — the web applications, and the BFF and orchestration services behind them that connect our experiences to platform services.
You own outcomes, not just your slice: you shape the "why" with Product and Design, lead projects end-to-end with light-touch steering, and raise the craft, accessibility and performance of your team's surfaces.
Who Thrives in This Role:
What You’ll Do**
Own the Delivery:** Lead projects end-to-end across our React, Next.js, and Python stack. Ship small, frequent updates and own your deployment, infrastructure, and on-call support.
Shape the Scope: Partner with Product and Design early. Pressure-test ideas, define all user states upfront, and aggressively cut scope to protect timelines.
Integrate AI Thoughtfully: Build AI features with transparency and user fallbacks, while championing agentic engineering habits (TDD, curated context) across the team.
Raise the Bar: Champion accessibility, performance, and security from day one. Document trade-offs clearly and keep code reviews moving by focusing on intended behavior.
Multiply Your Impact: Mentor early-career engineers through pairing and empathetic, judgment-building feedback.
What you'll bring
Frontend & BFF: Proven production experience with React, Next.js, TypeScript, and Tailwind CSS. Ability to design and own Python BFF and orchestration services (API contracts, auth, platform integration).
AI & Agentic Engineering: Hands-on experience building AI-powered customer features (managing streaming, latency, and non-deterministic outputs). Working knowledge of context engineering, verification loops, and evals.
Architecture & UX: Fluent in responsive component architecture. Transforms Figma prototypes into scalable UI with strict, routine adherence to WCAG AA 2.x standards.
Infrastructure & DevOps: Experience deploying and operating services on GCP using GitHub Actions, containers, Kubernetes/Helm, and Infrastructure as Code (Pulumi).
Quality & Observability: Writes comprehensive automated tests (unit, component, e2e). Drives architectural and product decisions using New Relic, Core Web Vitals, and telemetry.
Engineering Mindset: Pragmatic under shifting priorities. Proactively targets workflow inefficiencies, balances security with maintainability, and actively drives personal growth and community practices.
At Serko, we aim to create a place where people can come and do their best work. This means you’ll be operating in an environment with great tools and support to enable you to perform at the highest level of your abilities, producing high-quality and delivering innovative and efficient results. Our people are fully engaged, continuously improving, and encouraged to make an impact.
