Lead Software Engineer - Platform in London

Location: London (Hybrid – 2 days per week in our Spitalfields office)

Team: Engineering

About Trint

Trint turns audio and video into searchable, editable text. Our customers - major broadcasters, news agencies, and media organisations - depend on us when stories are breaking and speed matters. We’re a team of around 40 people building technology that sits at the heart of how stories get told. We take security seriously because our customers have to, and we ship small changes frequently because that’s how you build something people can depend on.

The role

We’re looking for a Lead Software Engineer to work with others to improve our platform infrastructure and shape how we build reliable, scalable systems at Trint. This is a technical leadership role, not a management one. You won’t have direct reports, but you will have significant influence. You’ll make decisions that affect how the whole engineering team works, mentor engineers across the function, and be the person we look to when it comes to infrastructure, reliability, and operational excellence. You’ll work closely with the VP of Engineering to shape technical direction. In a team of our size, you’ll be embedded wherever the work requires, we run a single standup across both squads and value engineers who move fluidly to where they’re needed most.

The context:

We’re projecting significant growth in 2026. Our systems need to scale accordingly, and our platform foundations need to support faster, more reliable delivery. You’ll be central to making that happen – from observability and developer experience to the infrastructure patterns that underpin everything we ship.

What you’ll do

• Alongside the other Lead Engineers you’ll support and guide the team to shape the platform and infrastructure.
• You’ll be responsible for the reliability, scalability, and operability of our systems. That means CI/CD pipelines, infrastructure‑as‑code, observability, incident response, and the day‑to‑day health of production.
• You’ll make sure we can ship with confidence and sleep at night.
• Shape technical direction. You’ll work with the VP of Engineering and the wider team to make architectural decisions that stick.
• You’ll provide guidance on new platform development, challenge assumptions, and help us make good trade‑offs between speed, reliability, and complexity.
• Raise the bar. You’ll mentor and coach engineers across the team. You’ll lead by example in code reviews, pairing sessions, and technical discussions.
• When something’s not right, you’ll communicate clearly, and help fix it.
• Deliver. This isn’t an ivory tower role. You’ll write code, ship to production, and own problems end‑to‑end. You’ll be hands‑on with the systems you’re responsible for.
• Be a bridge. You’ll help product engineers understand operational concerns, and make sure platform work stays connected to customer value.
• You’ll contribute to a culture where everyone thinks about reliability, not just the "platform person".

Our stack: AWS, MongoDB, GraphQL, React, TypeScript, Python, Terraform. We have strong DORA metrics, we pair program, we deliver value in small increments and observe change. The tooling and process exist to help us move faster – we use them, we own them, they don’t own us.

What we’re looking for

• 5+ years of software engineering experience, with meaningful time spent in DevOps, SRE, or platform engineering roles
• Deep experience with AWS and infrastructure‑as‑code (we use Terraform, SST/CDK)
• A strong grasp of what it takes to keep production systems reliable: CI/CD, observability, incident management, capacity planning
• Experience designing systems that scale – and debugging them when they don’t
• Enough breadth across the stack to understand how infrastructure decisions affect the engineers building on top of it
• Experience building services on the stack, not just building the stack

You are:

• A technical leader who influences through expertise and trust, not authority
• Opinionated but pragmatic – you have strong views, loosely held, and you can articulate trade‑offs clearly
• Someone who has lived through enough production incidents to know what matters and what doesn’t
• Genuinely invested in helping other engineers grow
• Clear in your communication – you can explain complex systems to people who don’t live in them every day

Bonus if you have:

• Experience with media processing pipelines or high‑throughput data systems
• Background in security‑conscious environments (enterprise, media, regulated industries)
• Familiarity with AI/ML infrastructure and how models integrate with production systems

What we offer

You’ll work on systems that matter, with people who care, in a company small enough that you can see your impact. You’ll have the autonomy that comes with trust, the influence that comes with expertise, and the support that comes from being part of a team that values doing things right.

Our values:

• Take risks. We focus on progress, not perfection. We make informed decisions and course‑correct when needed.
• Have impact. We deliver in days and weeks, not months. We’re obsessed with making a difference to our customers.
• Do the right thing. We communicate honestly. We take responsibility — even when no one is watching.
• Win together. It’s about we, not me.
