Senior Software Engineer

Location: Kuala Lumpur / Hybrid (Malaysia) Type: Full-timeAbout PantasPantas is an AI-first climate software company helping businesses measure, manage, and reduce their carbon emissions and ESG risks. We work with leading financial institutions and corporates to turn complex climate data into decisions that matter. We’re now rebuilding our platform with an AI-native approach – from how features are scoped and coded, to how customers experience the product.Why this role is different·      You will have access to leading AI coding assistants (Claude Code Max as primary, plus Jules, Codex, GitHub Copilot, CodeRabbit, and others) - use what works best for each task for coding, refactoring and debugging work.·      Everyone, including non-technical teammates, uses AI tools (ChatGPT, Gemini, Claude, Perplexity, etc.) and is encouraged to prototype workflows and AI agents themselves. AI isn’t a separate team – it’s the default way we work.·      Our CEO and CTO are both technical founders who code is a technical founder who codes, builds AI products, and runs monthly deep-dive AI workshops on topics like advanced prompting, AI agents, model temperature, vector embeddings, MCP, context engineering, RAG, DSPy, and more.·      You’ll collaborate with our Data Science team on generative AI products that use both frontier and open-source models (ChatGPT, Claude, Gemini, Mistral, DeepSeek, Qwen, GLM, etc.) and modern AI infrastructure (Databricks, OpenRouter, AWS SageMaker, Google Vertex AI).·      If you want to ship real software while levelling up as an AI-native engineer, this is the kind of environment you’re joining.The RoleAs a Senior Software Engineer, you will help design and build the next generation of Pantas’ climate and ESG platform. You’ll own meaningful parts of our backend and/or full stack, work closely with product, business analysts, and data science, and help define what “AI-first engineering” looks like for the team. You’ll like this role if you enjoy hands-on coding, system design, and working directly with LLMs and AI tooling to deliver features faster and smarter.How you’ll work with AI at PantasThis is what “AI-first” means in practice for you:·  AI-driven product workflowOur Business Analysts and product team use an AI PRD Agent to turn ideas into structured PRDs.AI then helps generate a technical implementation plan, which you refine and turn into production-ready code. ·  AI-assisted coding as defaultYou’ll use tools like Claude Code Max, GitHub Copilot, CodeRabbit, Google Jules and others for writing and refactoring code, generating tests and improving coverage, debugging and performance tuning. ·  Design-to-code with Figma MCPWe use Claude Code + Figma MCP to convert Figma/front-end designs into starter code, which you then clean up, harden, and ship. ·  Building generative AI featuresWork with our Data Science team to build genAI-powered features for climate and ESG: data extraction via LLM, document understanding, smart workflows, decision support, etc. You’ll work with LLMs and orchestration (prompting, retrieval, agent flows) across both proprietary and open-source models. ·. Continuous AI upskillingJoin monthly AI workshops led by both the CEO and CTO on topics like advanced prompting, AI agents, RAG, embeddings, MCP, DSPy, and new toolkits. Experiment with new AI infra and platforms (Databricks, OpenRouter, SageMaker, Vertex AI, etc.) as we evolve our stack.What you’ll get to do·      Design, build, and maintain scalable backend and/or full-stack services for our platform.·      Turn AI-generated PRDs and implementation plans into secure, robust, production-grade systems.·      Integrate with external systems (banks, partners, customer data sources) and ensure data is clean, consistent, and auditable.·      Ship AI-assisted workflows and features that help customers collect, validate, and analyse their data.·      Collaborate with product, business analysts, and data science to rapidly prototype via AI, then iteratively refine into stable features.·      Contribute to system architecture, coding standards, and our AI engineering playbook for Pantas.·      Mentor other engineers in using AI tools effectively and help raise the bar for AI-native engineering across the team. What you’ll need to succeed·      Solid experience (typically 3-5 years) as a software engineer in backend or full-stack roles, comfortable owning features end-to-end.·      Strong skills in at least one modern backend stack (e.g. Python/Django, Node.js, etc.) and experience with SQL databases.·      Experience building web applications or APIs used in production environments.·      A habit of writing clean, maintainable code, with tests and monitoring.·      Comfort working in a fast-moving startup environment: shipping iteratively, handling ambiguity, and collaborating closely with non-engineering teammates.·      AI-first mindset – you’re excited to treat AI as part of your stack, not a separate tool. You’re already using (or keen to master) coding assistants like Claude Code, Codex, GitHub Copilot, etc.Great if you also have: ·      Experience mentoring other engineers or influencing engineering practices.·      Exposure to cloud platforms (AWS/GCP/Azure) and data/ML infra (e.g. Databricks, SageMaker, Vertex AI, OpenRouter).·      Experience building or integrating LLM-powered features (e.g. RAG, agents, prompt orchestration, chat workflows).·      Interest or experience in climate, ESG, or fintech.Our AI-first culture·      Every team member, including non-technical roles, is encouraged and supported to code small scripts, build prototypes, and create AI agents to automate their work.·      We share internal playbooks, prompts, and workflows so that AI adoption compounds over time instead of living with a few experts.·      Engineers are not just “users” of AI – you help shape how the whole company uses AI.What we offer·      The chance to build meaningful software that helps businesses decarbonise and access sustainable finance.·      A hybrid, flexible work environment based in Malaysia.·      Direct access to a technical, AI-literate CEO and a team that genuinely wants to push the boundary on AI-assisted work.·      Competitive salary, ESOP, and a learning-heavy environment where you’ll grow as both a senior engineer and an AI practitioner.We celebrate diversity at our company and are proud to be an equal opportunity employer. We do not discriminate on the basis of race, religion, color, national origin, gender, age, marital status, sexual orientation or disability status.If you’re a senior engineer who wants to build real products, in a real market, with AI at the centre of how you work, we’d love to talk.
