Role

We’re looking for a Senior Engineer to work across data pipelines, LLM workflows and front-end delivery, according to the product and business requirements. You’ll join our engineering team as a foundational member, shaping the roadmap and technical culture from day one:

  • Design and build enterprise-grade systems providing digital advertising insights and automation. 
  • Collaborate with founders to prioritize product features and define tech strategy.
  • Drive key technical decisions, from choosing frameworks to shaping DevOps pipelines.
  • Contribute to Plug’s engineering practices so that our small team can achieve an incredible amount of great work.
What you build

You develop the killer app at the cutting edge of AI for a niche domain with a huge potential to scale to adjacent use cases. This includes building: 

  • The technical foundation of a company poised to transform digital advertising.
  • Advanced backend systems to process and analyze a massive amount of paid social performance data.
  • AI systems to analyze vast creative (text, image, video) datasets to extract actionable creative insights. 
  • Prototyping and developing practical, scalable automation workflows to make the lives of digital advertisers easier.
  • Efficient and scalable AI-powered creative production pipelines, cleverly utilising existing off-the-shelf solutions like image-to-video and human-like avatar capabilities.
  • Slick and intuitive frontend on your preferred stack to make complex data actionable for non-technical users. 
  • We currently work with a tech stack including Google Cloud Platform, Gemini/OpenAI APIs, BigQuery, Supabase, Gumloop,  Firecrawl, and Linear – we expect you to contribute to the evolution of this stack.
Qualifications

We don’t expect expertise in every area, but these are the technologies and practices you’ll regularly encounter.

  • Strong expertise in processing and analysing large datasets, especially in environments like PostgreSQL and BigQuery. You write efficient queries and know how to optimize performance.
  • Experience or strong motivation to work with RAG and LLMs, at scale and efficiently. 
  • Excellent taste in product and UI design. You have a strong sense of what makes a great user experience and care about the details.
  • Full-stack mastery with modern JavaScript/TypeScript stack. You can own entire features from backend to frontend.
  • You write scalable, maintainable code, have experience with long-term tech decisions and you can build and ship high-quality web applications.
  • Genuine passion for AI tools of the future
  • Streamlining and accelerating development lifecycle with strong CI/CD best practices.
  • Experience with social platform related databases like Meta Graph API.
For who

We appreciate raw talent and willingness to learn alongside expertise. We look for people who: 

  • Prioritize ruthlessly and thrive with high autonomy.
  • Solve problems with a bias for action, owning challenges end-to-end rather than just one layer.
  • Embrace ambiguity with an entrepreneurial mindset: this isn't a role with comfortable, well-defined tasks but requires willingness to push boundaries and experiment.
  • Obsess over customer needs, building with advertisers through tight feedback loops.
  • Demonstrate curiosity and continuous improvement in everything you do.
  • See the big picture beyond technical challenges while maintaining a high bar for quality.
  • Communicate complex technical decisions clearly as a true team player to technical and non-technical people.
  • Have demonstrated experience in building high-quality software solutions from scratch.
Benefits
  • Build real value at the bleeding edge of Generative AI, RAG systems, and LLM agents with immediate real-world impact.
  • Work directly with company founders and a smart, driven team of domain experts.
  • Opportunity to shape the technical foundation and team culture of an early-stage startup with massive growth potential.
  • Directly influence product direction and company strategy as a key technical talent.
  • Take on challenging work in a fast-paced environment with potential to grow into Lead or Head of roles as the team scales.
