Senior Full Stack Developer

SimplifyNext is a Singapore-headquartered digital engineering firm, with offices in Thailand and Malaysia, working across three converged areas: agentic AI, AI-enabled application modernisation, and intelligent automation.

We bring strong business process consulting together with deep technology skills and modern delivery practices - product-centric, agile and AI-assisted. We build bespoke applications and AI systems, and we go deep on the platforms our clients run on, including Microsoft, AWS, ServiceNow, Databricks and UiPath. That combination of engineering depth and platform depth is what our clients come to us for.

We build and modernise the systems people depend on daily. Our 300+ practitioners are multi-disciplinary by design - business consultants, software engineers, architects, AI engineers and designers working on the same delivery, not handing off between silos. We focus on delivering outcomes for clients, building strong careers for our people, and staying ahead of the technology curve. We hire because we are growing.

What You'll Own

• Build and own backend services and frontend interfaces - from the API and business logic all the way through to what the user actually sees
• Take features from 0 to 1 when there's nothing there yet, and confidently improve systems that already exist
• Build the integration layer that lets different systems - and in some projects, different business units / organizations - talk to each other and share data reliably
• Take real ownership through deployment and monitoring - not just “write code and hand it off”
• Work closely with PMs, designers, BAs, and QA to turn requirements into shipped, tested, working software

What You'll Bring

Must-Have

• We're hiring across levels - from around 3 years to 8+ years of experience. Depending on your depth in the areas below, tell us where you land and we will match you to the right level of role
• Strong full-stack ability, with real depth in at least one of:
  • Backend: Kotlin, Golang, or similar
  • Frontend: Next.js, React, or similar
• A track record of building and owning systems end-to-end, not just contributing to them
• Solid coding fundamentals - you can write and reason about production code independently, without needing an AI assistant to do the thinking for you
• Comfortable digging into legacy systems and making them better, not just building new things
• Experience with Git, microservices, event-driven systems (Kafka, RabbitMQ), containers (Docker, Kubernetes), and CI/CD pipelines
• Familiarity with cloud environments and modern DevOps practices

Good-to-Have

• Experience in government environments and familiarity with government tech stack, if not you will learn with us
• Exposure to data integration patterns across multiple systems
• You use AI coding tools (it is the present and the future) - not as a crutch, but thoughtfully to move faster
