Role
Who you are
- We’re looking for an experienced, creative, and versatile engineer who is eager to tackle the challenge of architecting, building, and scaling the core infrastructure and systems powering Lightfield's AI-driven CRM
- 3+ years of experience in software development, with a strong background in infrastructure, data modeling, and backend systems
- Deep experience building scalable, high-performance data infrastructure that can support complex customer workflows and large-scale data processing
- Strong understanding of database design, indexing strategies, and query optimization, especially in PostgreSQL or similar relational databases
- You’re excited about Large Language Models (LLMs) and the opportunity to build systems that support and leverage them
- You have the ability to ramp quickly on tech stack that features TypeScript, React, Next.js, Node.js, Apollo GraphQL, and PostgreSQL
- Strong fundamentals in software engineering, with a degree in Computer Science or a related field
- Thrives in ambiguity, able to independently drive projects and deliver results in a fast-moving environment
- Clear communicator, capable of articulating technical decisions to both technical and non-technical stakeholders
- Passionate about building products customers love, ensuring our CRM is intuitive, intelligent, and indispensable
What the job involves
- At Lightfield, engineers take ownership of projects from inception to impact, collaborating across functions and pushing the envelope on what’s possible in applied AI and data systems
- You’ll play a critical role in designing and building the data models and infrastructure that support a next-generation CRM, ensuring our system is performant, scalable, and resilient
- Build and maintain full-stack systems, end-to-end, ensuring reliability, scalability, and performance
- Architect and scale the data infrastructure and backend services that power Lightfield AI-driven CRM
- Design and optimize data models to support CRM workflows, customer interactions, and AI-driven insights
- Develop observability and metrics to enable smooth operation, proactive issue detection, and continuous improvement
- Mentor teammates, participate in code reviews, and help shape engineering culture and practices
- Contribute to building a world-class engineering team through recruiting, mentorship, and knowledge-sharing
Our take
A major pitfall of CRM systems is the amount of admin required to maintain them. Follow up drafting, note logging and field updating mean that customers are always playing catch up to maintain the very system built to keep them on top of their customer relationships. Lightfield was designed to do this work itself, utilising AI-native automation to build a picture of your customer base.
Lightfield’s AI agents can contextualise customer interactions and use this to develop unique sales pipelines and meeting preparation, meaning that its users do less admin and close more deals. Tools on the Lightfield platform include a pipeline generation tool for time-strapped start-ups, a sales assistant for meeting memos and log updating and data capture for self-updating CRMs. All this speaks to a product that speaks to a culture of bogged-down, high-growth companies lacking the time to manage their growing client base.
Spun out from the co-founders' previous pitch-presentation company Tome, Lightfield released a migration tool in 2026, further incentivising businesses to take up its platform. With plenty of experience from its founding team, Lightfield is itself on the right track for high growth.
