Shape a team. Collaborate with fellow Devs and DevOps Engineers. Show them how you can make everyone's day either better, easier or merely a little less painful. Be the resource that helps applications be developed, released and deployed with minimal fuss. It's not always possible but it's always the aim.
That's what a good DevOps Engineer does. That's what you do.
You'll know your way around AWS and you thrive in performing CI/CD implementation with Jenkins involved. If you like the idea of doing it in a company where you'll collaborate with seasoned engineers and earn their respect, then you'll enjoy working here. Scripting (e.g. bash, php, python) is second nature to you and you appreciate the long-term benefits of automating things.
You’ll make a difference from Day One. This company isn't corporate - it also offers variety in your day, a pleasant environment of people and you'll all share a common goal to deliver great software. Working hours are flexible and the team is operating remotely for the foreseeable future, although being commutable to Northampton would be useful for ad-hoc meet-ups.
