About Signal

At Signal we want to help organisations identify risks and opportunities and see movements in the market before anyone else. We want to help leaders make bold decisions, safe that the data is on their side. We want to connect all those external data points together, uncover the unknown unknowns, and be at the very heart of the knowledge economy. We’ve already built a world‑class artificial intelligence platform for real‑time information aggregation and analysis at a massive scale. We proved our value with monitoring and measurement products in the PR&Comms space, and are now joining the dots beyond. We are friendly and informal people who are passionate about our brand as we all have a stake in our success. We have an inclusive environment, welcoming the skills and experience from many diverse backgrounds, and together we have created who we are and what we sell. We are proud of our achievements and continue to strive for the unknown.

What you’ll be doing

This role suits someone with a strong product mindset who is comfortable tackling complex problems across the full stack.

As member of the Reputation Team you will be:

• Work in a highly collaborative environment, with a significant amount of time spent pair programming
• Maintain and evolve an existing web‑based product
• Implement and maintain the infrastructure supporting your team’s services, using Terraform for infrastructure as code and AWS as cloud provider
• Build and operate services capable of handling large volumes of data
• Work across a varied technology stack, including Clojure, Python, React, and GraphQL
• Work with both relational and non‑relational databases and storage systems (e.g. ElasticSearch, PostgreSQL, S3, Redis)
• Collaborate on defining and delivering products from both technical and product perspectives
• Communicate effectively with other teams and stakeholders as needed
• Provide coaching and mentoring to less experienced engineers
