Who you are

- Strong expertise in building production-grade backend systems with Python and/or Go
- Solid experience with distributed systems and event-driven architectures
- Proven track record with AWS services and cloud-native development
- Strong foundation in database technologies (MongoDB, PostgreSQL, Redis)

What the job involves
- We're seeking a talented backend engineer to build and scale core systems powering our AI-first sales platform
- As a key individual contributor, you'll develop critical components of our seller co-pilot system, working at the intersection of backend services and AI infrastructure
- This is an exciting opportunity to own end-to-end development of systems that are transforming how B2B sales teams operate
- Build scalable, easy-to-maintain backend services that power our AI co-pilot features using Python/Go
- Implement elegant event-driven systems using AWS services for real-time AI processing
- Create robust data pipelines and APIs that handle complex sales workflow automation
- Design and implement efficient database schemas and data flows across MongoDB, PostgreSQL, and Redis
- Build monitoring and observability solutions for production systems

Our take
To help sales teams maximise their time, Sybill provides an AI that reduces the time spent on administrative tasks so that they can instead focus on building client relationships.
It's a simple but effective proposition. Sybill's AI can take deal notes, draft tone-correct follow-up emails and write process-aware CRM updates. Its model was built specifically for sales, making it a better option than more generic AI admin tools.
The company has raised significant funds, the latest of which will be used to further the development of its AI and build out its team. With upwards of 500 paying customers, the company has got off to a great start and is set up nicely for future growth.
