Full Stack Engineer



Job description

About Transmission
We’re the world’s largest independent global B2B marketing agency, where curious minds create the future.

If you’re someone who’s thought-provoking, ego-quashing, mistake-learning, all-including, convention-breaking, and always-growing with a passion for what you do, you’ll fit right in.
We’re one agency spread across eight global offices, and we let our work do the talking.

Our recent accolades include Global B2B Agency of the Year at the B2B Marketing Awards, Agency of the Year at the Elevation Awards, and wins at The Drum Awards, B2 ANA Awards, and Marketing Excellence Awards, Singapore.
About the Role
We are looking for a Full-stack Engineer with strong product-building experience across the front-end, back-end, and data layers.

You’ll work on applications that bring together modern web technologies, scalable cloud infrastructure, and applied AI/LLM solutions.

A successful candidate will have hands-on expertise with React/TypeScript, FastAPI (Python), and Snowflake, and be comfortable deploying and operating systems in AWS.
Experience with LangChain and vector databases (e.g., Pinecone, Weaviate, FAISS, or pgvector) is a major plus, as you’ll contribute to features that leverage LLMs, embeddings, and retrieval-augmented generation.
What you'll do:
- Build and maintain scalable web applications using React/TypeScript (front-end) and FastAPI/Python (back-end).
- Design and optimize data models and SQL queries in Snowflake, including handling semi-structured data (VARIANT).
- Architect and deploy cloud-based services on AWS ECS/Fly.io, integrating with SES (email) and Secrets Manager.
- Implement authentication and authorization flows (JWT, MFA) and ensure application security best practices.
- Develop LangChain-powered services, integrating vector databases for semantic search, RAG pipelines, and conversational AI features.
- Build and maintain CI/CD pipelines with GitHub Actions, ensuring reliable, automated deployments.
- Write robust unit, integration, and end-to-end tests to ensure application quality and reliability.
- Profile and debug applications for performance, scalability, and resilience.
- Work closely with cross-functional teams (data, product, design) to deliver new features end-to-end.
- Contribute to architecture decisions and mentor junior engineers.
What you'll bring:
- 5–8 years of professional software engineering experience.
- Proficiency with React, TypeScript, JavaScript, and front-end best practices.
- Strong back-end development experience with Python (FastAPI or similar).
- Experience with Snowflake SQL (including VARIANT).
- Hands-on experience with AWS services (ECS, Fly.io, SES, Secrets Manager).
- Familiarity with authentication/security frameworks (JWT, MFA).
- Experience building and deploying CI/CD pipelines (GitHub Actions preferred).
- Strong background in software testing, debugging, and performance tuning.
- Experience with LangChain (agents, chains, retrievers) and vector databases (e.g., Pinecone, FAISS, etc).
Nice to Have
- Familiarity with infrastructure-as-code (Terraform, AWS CDK).
- Exposure to data engineering workflows and LLM application patterns.
Why Join Us
- Work across the full stack, including applied AI/LLM features.
- Join a collaborative, innovative culture with ownership of high-impact projects.
- Competitive compensation, benefits, and professional growth opportunities.
