Senior Software Engineer in London

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

About Trint

Trint turns audio and video into searchable, editable text to provide insights or that raw quote. 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, with 17 in product and engineering, building technology that sits at the heart of how stories get told. We’ve been "human in the loop" AI since before it was a buzzword. 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 Senior Software Engineer to join our team. Someone who’s comfortable across the full stack, thinks with a DevOps mindset, and has a genuine hunger for infrastructure work. You’ll be part of a small team where your voice matters. Technical decisions here aren’t handed down - they’re made by the people doing the work. If you’ve been waiting for the chance to have real influence on architecture and direction, this is that opportunity.

The immediate challenge:

We’re reshaping our media pipeline to handle significantly increased volume projected for 2026. You’ll be central to that work, designing, building, and scaling the systems that process media for some of the world’s largest news organisations.

What you’ll do

• You’ll work across our stack, but leaning towards infrastructure.
• You’ll write code, review code, pair with colleagues, and ship to production regularly.
• You’ll help us make the architectural decisions that will define how Trint scales.
• You’ll own problems end-to-end - from understanding what needs to be built, to getting it into the hands of customers, to making sure it stays running.

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

• Strong experience building and operating software in production, particularly on AWS.
• A solid grasp of infrastructure-as-code, CI/CD, and what it takes to keep systems reliable.
• The ability to work across the stack, you’ve got a preference for sure, but you’re comfortable with both frontend and backend.
• Experience with the realities of scaling systems: what breaks, why, and how to design around it.

You are:

• Someone who takes ownership, you don’t wait to be told what to do.
• Pragmatic about trade-offs and able to articulate them to others.
• Genuinely interested in how things work underneath.
• A good colleague - you communicate clearly, you help others, you assume good intent.

We’re also open to:

Engineers currently at mid-level who are ready to step up. If you’ve got the capability but haven’t had the opportunity but you believe you operate at a senior level - perhaps due to the structure of your current role - we’d like to hear from you.

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, and the support that comes with being part of a team. We’re not big on hierarchy for its own sake, we’re structured enough to be supportive, flat enough to be effective and human.

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.
