Software Engineer - 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.
Working within a highly supportive team, you will shape the application experience layer—building the web apps, BFFs, and orchestration services that connect our platform directly to the customer. With light-touch guidance, you will elevate the craft, accessibility, and quality of our user-facing products.
You are someone who understands the "why" behind the work, operates with high agency, and ships small, high-impact changes frequently.

What you'll do

• Work closely with Product, Design and Engineering, modelling strong engineering standards and teamwork.
• Understand the customer problem and success measure, and check that what you ship moves it.
• Help shape work into small, shippable slices with requirements anyone, or any agent, could check.
• Independently deliver well-scoped features to production, in line with our stack and design system.
• Implement designs faithfully and accessibly, including responsive behaviour and empty, error and loading states.
• Build and extend the BFF endpoints your features need in Python.
• Build AI and agent-powered features for customers using our established patterns for streaming, latency, errors and non-deterministic output.
• Work agentically by default, giving agents clear tasks and context, writing tests from requirements first and verifying output before it ships.
• Make reversible calls yourself; escalate anything that changes what ships or is costly to undo.
• Lead small projects with coaching, planning the work, running stand-ups and keeping stakeholders informed.
• Deploy and support what you build, including on-call and infrastructure changes with guidance, and instrument both system health and customer outcomes.
• Contribute ideas that improve how the team works and what it ships.

What you'll bring

• Solid React/Next.js and TypeScript, and customer-facing features shipped to production.
• Working experience building APIs in Python or another backend language.
• Accessibility fundamentals, including semantic HTML, keyboard navigation, colour contrast and ARIA.
• Plans and executes work effectively, balancing speed and quality and adapting when priorities shift.
• Designs small, simple, maintainable solutions that avoid common security vulnerabilities.
• Contributes to team technical discussions and recognises dependencies in the team's system.
• Uses tests, metrics and dashboards to improve quality and reliability.
• Deliberately builds understanding of the code you ship, so judgement grows alongside agentic productivity.
• Supports peers through review and knowledge sharing, helps align the team around agreed approaches, and shows awareness of others' perspectives.
• Own your growth, setting goals, seeking feedback and keeping a record of your impact.
