Job Description

About Signal - Who are we?

We're on a mission to change the way businesses make decisions with our cutting-edge AI technology. To achieve that, we’re looking for passionate people to join our open and unconventional workplace. Our inclusive environment welcomes skills and experiences from diverse backgrounds, and defines who we are.

About the role - what’s your purpose?

Staff Engineers at Signal AI are highly experienced individual leaders and seasoned technical experts whose influence extends beyond their team. They are recognised by their peers as an authority in a domain or technology and other engineers often seek their opinion when facing highly complex problems. They collaborate in parallel across engineering teams and with others in similar roles to help drive initiatives and solutions forward.

Staff Engineers form our senior leadership team within the company and often assume the role of Tech Lead for their team. They can confidently play a significant role in helping Signal AI achieve our business goals. They do this by focusing on high impact, high value work which likely involves our largest and most ambiguous problems, driving discovery work and mobilising their team to deliver.

You’re a technical authority and influence towards effective solutions. Your role is as much about being a force-multiplier for your team as it is about being an individual contributor. You recognise that you can have the most impact by helping your team to do their best work.

Day-to-day responsibilities - What will you be doing?

  • You love building products as part of a cross-functional team focused on an iterative, outcome-driven approach.
  • You believe in collaboration as a way of working and are keen on following our trunk-based development strategy via pair programming.
  • You understand the benefits of the DevOps mentality and are comfortable building new solutions while being responsible for the day-to-day operations of existing ones.
  • You have experience with large-scale distributed systems that are both resilient and observable.
  • You have a self-starter mindset; you proactively identify issues and opportunities and tackle them without being told to do so
  • You have strong communication skills and are comfortable expressing your ideas to technical and non-technical audiences.
  • You have a positive attitude and are keen to learn new skills while enhancing those you already have.
  • A bonus if you have worked with Clojure, Terraform and AWS.
