About Airwallex
Airwallex is the only unified payments and financial platform for global businesses. Powered by our unique combination of proprietary infrastructure and software, we empower over 150,000 businesses worldwide - including Brex, Rippling, Navan, Qantas, SHEIN and many more - with fully integrated solutions to manage everything from business accounts, payments, spend management and treasury, to embedded finance at a global scale. Proudly founded in Melbourne, we have a team of over 1,800 of the brightest and most innovative people in tech across 26 offices around the globe. Valued at US$6.2 billion and backed by world-leading investors including Visa, Airtree, Blackbird, Sequoia, DST Global, Greenoaks, Salesforce Ventures, Lone Pine, and Square Peg, Airwallex is leading the charge in building the global payments and financial platform of the future. If you're ready to do the most ambitious work of your career, join us. Attributes We Value
We hire successful builders with founder-like energy who want real impact, accelerated learning, and true ownership. You bring strong role-related expertise and sharp thinking, and you're motivated by our mission and
operating principles . You move fast with good judgment, dig deep with curiosity, and make decisions from first principles, balancing speed and rigor. You're humble and collaborative turn zerotoone ideas into real products, and you 'get stuff done' end-to-end. You use AI to work smarter and solve problems faster. Here, you'll tackle complex, highvisibility problems with exceptional teammates and grow your career as we build the future of global banking. If that sounds like you, let's build what's next. About The Team
The
Citizen Developers Infrastructure
team sits within the
Infrastructure & Productivity
organization and is responsible for the internal platform that powers critical business processes at Airwallex. We build and operate a
citizendeveloper platform
that lets nonproduct engineering groups safely build and run workflows and automations. Our goal is to make it easy and safe for these 'citizen developers' to ship value quickly while embedding security, compliance, and software engineering best practices by default. This role is based in
Singapore . What You'll Do
As a
Senior/Staff Software Engineer
on the Citizen Developers Infrastructure team, you will design, build, and operate the
platform services that underpin Airwallex's citizendeveloper ecosystem and internal workflow automation . You will partner closely with application teams and citizen developers to define tooling, patterns, and development processes, while continuously improving the platform abstractions and paved paths they build on. You'll be responsible both for the
developer experience and guardrails
of the platform, and for the
underlying workflow infrastructure
that makes it reliable and scalable. Responsibilities
Design, build, and evolve the
citizendeveloper platform and tools
that make it easy to create and operate automation / applications without deep infrastructure knowledge.
Establish
secure SDLC and guardrails
for citizendeveloperbuilt applications so compliance and security are baked in by default.
Build
selfserve development and operations tooling
that reduce dependence on central platform engineers.
Design, build, and maintain the
Temporalbased workflow infrastructure , addressing challenges such as multitenancy, high availability, and cost effectiveness.
Contribute to the
Kubernetes and GitOps foundation
(ArgoCD, Helm, Terraform) that powers the platform, ensuring deployments are safe, repeatable, and auditable.
Participate in
code reviews, technical design discussions, and oncall rotation
for workflowrelated services, leading incident response and driving longterm fixes where needed.
Document standards, best practices, and reference architectures
so teams building on top of the platform have clear, selfserve guidance.
Who You Are
You are a backend/platform engineer who enjoys
building shared platforms , cares deeply about
developer experience, correctness, and operability , and is comfortable working at the intersection of
application code and infrastructure . You get energy from enabling other teams to move faster safely, through welldesigned abstractions, tooling, and guardrails. Qualifications
6+ years of experience in
Software / Platform Engineering
roles, building and operating backend or platform services in production.
Strong handson experience with at least one
strongly typed backend language
(e.g., Golang, Java) and familiarity with
Python or Bash
for tooling/automation.
Experience
designing and building internal platforms or developer tooling
used by multiple teams, with a strong focus on developer experience.
Experience with
Kubernetes
and
GitOps
practices/tooling (ideally ArgoCD and Terraform).
Experience building platforms or tooling for
nonproduct engineering users
(e.g., operations, finance, analysts) or
lowcode/nocode / citizendeveloper environments
is a strong plus.
Proven experience with
Temporal or similar workflow/orchestration systems
(e.g., Cadence, Step Functions, Airflow) or largescale stateful workloads (e.g., Redis clusters, Cassandra, HBase) in production is a huge plus.
Comfortable working in
highly collaborative, multiteam environments , able to translate platform constraints into clear APIs, contracts, and paved paths for application teams and citizen developers.
Practical, proactive problem solver who can
navigate ambiguity , break down complex technical problems, and drive them to closure.
