Infrastructure Team Lead

We're looking for an Infrastructure Team Lead to take ownership of the systems that power our AI research and development, ranging from bare metal GPU clusters through to the internal services our engineers rely on every day. 

This is a broad role with technical depth and people leadership. You will set the technical direction of the Infrastructure team, drive reliability and continuous improvements across the stack – from physical layer through to the software layer. Additionally, you will be investing in your engineers through 1:1s, coaching and creating career development opportunities. 

We’re a team that gets things done properly and multiplies the impact of others. If that sounds like an exciting problem, we’d love to talk. 

What you'll be doing 

• Leading, managing, and developing a team of Infrastructure Engineers, setting clear objectives and fostering a high-performance, collaborative culture 

• Conducting regular 1:1s, performance reviews, and development planning to build technical capability and support career progression 

• Owning operational stability across our infrastructure, including hardware monitoring, troubleshooting and disaster recovery testing 

• Acting as the escalation point for technical and operational issues, leading major incident response and driving resolution 

• Leading infrastructure strategy, including capacity and project planning 

• Driving standardisation, automation and optimisation to reduce toil 

• Leading vendor relationships with hardware vendors, managed service providers and other external contacts 

Who we are looking for 

• Proven experience in an Infrastructure Team Lead or Senior Engineer role, with strong people management and coaching skills 

• Experience leading or mentoring engineers, including setting objectives and supporting career development 

• A desire to go deep into any subject and a genuine love of learning on the job 

• Broad knowledge of the infrastructure supporting distributed systems — operating systems, observability tooling, networking, storage, containers and container orchestration 

• Comfortable troubleshooting Linux systems (we use Ubuntu) 

• Solid experience with infrastructure-as-code and automation tooling — we use Terraform and Ansible extensively 

• Experience with bare metal provisioning — we use PXE booting to automate hardware OS installs 

• Strong networking configuration and troubleshooting skills, including DNS/DHCP/IPAM 

• Excellent written and verbal communication skills, with the ability to influence at all levels and report up and out 

We encourage you to apply even if you do not feel you match all of the requirements exactly. The list of requirements is intended to show the kinds of experience and qualities we’re looking for, but it is not exhaustive. If you are interested in the role, the team, and our mission, we would love to consider your application. We are always open to conversations and look forward to hearing from you.

We believe in putting people first; we’ll do all we can to help you develop your skills and give you the tools you need to thrive. Our Focus Fridays give you an undisturbed day of focus, offset with Together Tuesdays when we have our team meetings, so you've always got the right balance.

We have structured a hybrid approach that includes 2-3 designated office days each week. This arrangement ensures that while we embrace the advantages of remote work, we also maintain the vital connection and synergy that only in-person interactions can foster.

This is only the beginning; we’re looking for amazing people like you to continue our journey…

What we can offer you:

No matter what stage of your career you’re at - from paid internships and first-job opportunities through to management and senior positions - we’ll support you with the training and development needed to reach your career aspirations with us. There really is no shortage of opportunities here for you to get involved and collaborate with those around you to deliver your best work.

We offer incredibly flexible working, regular company lunches, and birthday celebrations. But that’s not all. We’ve spoken to our teams to find out what they want. From Private Medical, and Dental for you and your family, through to global working opportunities, a generous holiday allowance and pension/401K matching, we want to make sure our employees and their families are looked after. Every employee will receive a working from home allowance for tech or home office equipment (on top of your choice of laptop and accessories of course). Our approach to parental leave is designed to support employees globally. While this varies by geo, we have support in place for parents (including adoption assistance and reproductive health services) to ensure they have the time and financial resources needed to care for their growing families.

At Speechmatics, our mission is simple: Understand Every Voice out there. 

That's not just about our tech – it's the heart and soul of who we are. We welcome different experiences, viewpoints, and identities. For us, it’s not just the right thing to do; it’s our catalyst for sparking innovation and creativity. Our teams thrive in an environment that celebrates and supports everyone – no matter their gender, identity or expression, race, disability, age, sexual orientation, religion, belief, marital status, national origin, veteran status, pregnancy, or maternity status.

But we don’t just open the door to diversity – we actively welcome it. Why? Because we believe every unique voice adds something special to our team, leading us to smarter solutions and a better workplace.

So, come as you are and join our Speechling community. We’re building a place where every voice not only gets heard but is also respected and valued.
