Job summary

SimplifyNext is seeking a Senior Full Stack Software Developer to design, build and ship production-grade applications for clients—covering front-end, back-end and cloud environments. You’ll take features from concept to production, own deployments and monitor live services, and translate business requirements into robust, scalable software.

Collaboration with AI-assisted delivery, DevOps, and cross-functional teams is essential.

Qualifications

• 3 to 8+ years of hands-on experience in full-stack software development, delivering to production.
• Strong full-stack ability with real depth in at least one side - front-end (e.g. Next.js, React, TypeScript) or back-end.
• Solid back-end development experience (e.g. Kotlin, Golang, Java, Node.js, Python or .NET).
• Experience designing and consuming APIs, and working with relational and/or NoSQL databases.
• A track record of building and owning systems end to end, not only contributing to them.
• Solid coding fundamentals - able to write and reason about production code independently, without relying on an AI assistant to do the thinking.
• Comfortable working inside legacy systems and making them better, not only building new ones.
• Experience with microservices and event-driven systems (e.g. Kafka, RabbitMQ), and with containers (Docker, Kubernetes).
• Working knowledge of at least one cloud platform (AWS, Azure or GCP) and modern DevOps practices.
• Experience with Git, CI/CD pipelines and modern development workflows.
• Strong communication skills and the ability to work in cross-functional, client-facing teams.
• Degree or Diploma in Computer Science, Engineering or a related discipline.

Responsibilities

• End-to-End Feature Delivery: Design, develop and deploy full-stack applications using modern frameworks and cloud-native architectures.
• Take ownership of features or modules from requirement through to production release and post-deploy support.
• Take features from zero to one where nothing exists yet, and confidently improve systems that are already in production.
• Build the integration layer that allows different systems to exchange data reliably.
• Translate business and technical requirements into robust, maintainable, scalable solutions.

Job description

About SimplifyNext

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.

Role Purpose

The Full Stack Software Developer designs, builds and ships production-grade applications for our clients - across the front end, the back end, and the cloud they run on. You will take features from zero to one where nothing exists yet, improve and extend systems that are already live, and own what you build through deployment and monitoring. This role sits close to the work: you will translate business requirements into working software and use our AI-assisted engineering workbench as part of everyday delivery, not as an experiment.

What You’ll Own

• 1. End-to-End Feature Delivery
  Design, develop and deploy full-stack applications using modern frameworks and cloud-native architectures.
  Take ownership of features or modules from requirement through to production release and post-deploy support.
  Take features from zero to one where nothing exists yet, and confidently improve systems that are already in production.
  Build the integration layer that allows different systems - and in some engagements, different business units or agencies - to exchange data reliably.
  Translate business and technical requirements into robust, maintainable, scalable solutions.
• 2. Engineering Quality & Craft
  Apply best practices in code quality, automated testing, security and performance.
  Participate in code review, uphold architectural standards, and keep technical debt visible and managed.
  Produce clear technical and architectural documentation.
• 3. AI-Assisted Delivery
  Use SimplifyNext's AI workbench across the lifecycle - story refinement, code generation, test generation, review support and documentation.
  Work within our guardrails: human gates, drift checks, coverage contracts and CI-first verification.
• 4. Cloud, CI/CD & DevSecOps
  Collaborate with DevOps on CI/CD pipelines, cloud deployments and release automation.
  Embed security requirements from design - secure coding, access controls, vulnerability management.
  Own what you ship through deployment and monitoring, rather than handing work off at code complete.
• 5. Collaboration & Mentoring
  Work alongside project managers, designers, business analysts, QA and client stakeholders in one delivery team, turning requirements into shipped, tested, working software.
  Review code and mentor junior developers; recommend improvements to tools, frameworks and approaches.

Must Have

• 3 to 8+ years of hands-on experience in full-stack software development, delivering to production. We hire across levels and will match you to the right one based on your depth.
• Strong full-stack ability with real depth in at least one side - front-end (e.g. Next.js, React, TypeScript) or back-end.
• Solid back-end development experience (e.g. Kotlin, Golang, Java, Node.js, Python or .NET).
• Experience designing and consuming APIs, and working with relational and/or NoSQL databases.
• A track record of building and owning systems end to end, not only contributing to them.
• Solid coding fundamentals - able to write and reason about production code independently, without relying on an AI assistant to do the thinking.
• Comfortable working inside legacy systems and making them better, not only building new ones.
• Experience with microservices and event-driven systems (e.g. Kafka, RabbitMQ), and with containers (Docker, Kubernetes).
• Working knowledge of at least one cloud platform (AWS, Azure or GCP) and modern DevOps practices.
• Experience with Git, CI/CD pipelines and modern development workflows.
• Strong communication skills and the ability to work in cross-functional, client-facing teams.
• Degree or Diploma in Computer Science, Engineering or a related discipline.
