Tudor Evans CV

I’m a software engineer and engineering manager. I work mostly in web dev and distributed systems. I consider myself an all-rounder and enjoy working cross-functionally with product, marketing and sales. I believe in an output-focussed approach to management, and like working with high talent individuals who can be given ownership and responsibility over their own problem spaces.

As well as people management and tech, I love working as a communicator. I especially like written and spoken communication, and have received very positive feedback about my presenting and writing styles. I have a Substack newletter so you can make up your own mind!

In my current role at Speechmatics, I’m the team lead for our self-service product offering. Check it out at portal.speechmatics.com.

Experience

Senior Team Lead

Speechmatics · January 2026 – present

I manage a team of six engineers. The DevX team is responsible for auth, billing, platform services, SDKs, docs and product design. I run the team processes, manage the people and lead the tech. I also act as product owner/manager for our self-service product offering, setting OKRs for the team with input from the executive team. I produce the financial and data reports for the team, and identify our KPIs, with a focus on input metrics - time to value, sign-ups, feature uptake etc. In addition to my work with DevX, I run a team of contractors who look after our main website. I’ve worked with marketing to improve their operations and planning processes around this.

Some highlights:

  • In the time that I’ve been leading the team as people and, earlier, tech lead, self-service revenue has achieved 12% geometric mean month on month revenue growth.
  • New enterprise customer acquisition per quarter has doubled as a result of the reduced sales cycle from my team’s work. This includes work to improve customer visibility over usage patterns, reduce time-to-value for them to integrate our API into their stack, and rolling out enterprise-grade features such as MFA and finer-grained access control on shared accounts.
  • Changes to our auth system and UI, including the multi-user accounts feature, that I product managed and drove from a direction-setting perspective led to a tripling of the free -> paid user conversion rate (2.2%->6.3%) in the space of just three months.
  • I have created a user interview process for the company that has allowed our product and engineering teams to better understand the needs of developers interacting with our API. This process has been used when preparing to launch new features in the portal and a new Voice Agent builder-focussed STT API, to validate the new product features, and led to reduced dev time, more focus and higher feature quality.

Staff Engineer / Tech Lead

Speechmatics · July - December 2025

As the staff engineer / tech lead on the DevX team, I ran the day-to-day of the team and was responsible for line managing two of the team members. I set team goals and strategy, and worked with non-tech teams to understand customer requirements, manage backlog etc.

Some highlights:

  • I onboarded an engineer from a different team who had very low morale, and people managed him so that within six months he was exceeding expectations and on a promotion path.
  • I worked with the product design lead to shift the company towards a product-led growth model. That included presenting at Town Halls, presenting to the leadership team, and sitting down with marketing and sales to map out their processes and incentives and figure out how they would need to change to accommodate PLG. This has increased our revenue momentum from a point of low/no growth to a point of double digit percentage revenue growth per year.
  • I represented the company at VapiCon is SF, where I spoke to hundreds of developers and builders and registered some valuable leads for the company. Proof that I’m not just a good engineer and manager - I’m also a pretty face.
  • As a team we migrated our auth stack from Azure to WorkOS. I was responsible for building much of the core migration script, as well as acting as product manager and doing some project management / stakeholder communication. The goal for this project was to reduce bot spam, provide better social sign on and enable the release of a multi-user organisation system in Q1 2026. All of our goals were achieved, though the timeline was longer than expected, and we able to almost completely eliminate abusive accounts (more than 100 blocked a day!).

Senior Software Engineer I & II

Speechmatics · January 2023 - July 2025

As a senior engineer on the team, I was responsible for maintaining the backend and front end systems. I was also instrumental in the decision-making and planning around the launch of our mobile app for marketing purposes.

Some highlights:

  • I was tech lead on a project to redesign our global system architecture from a RESTful synchronous system to a highly available asynchronous event-driven platform, based on Apache Kafka.
  • I built a flexible, multi-region billing and auditing system for real-time customer telemetry, based on an Apache Kafka backbone, which is still in production 3 years later and now handles 12 million events every day, with minimal changes.
  • I worked as tech lead on a project to ship a production-grade AI agent configuration and management platform, which formed one of the two core pillars of a new product offering the company was pushing. Sadly, the product offering didn’t succeed in the end (ask me about this, I love to unpick the reasons!), but I think we did some great work nonetheless.
  • My team a React Native mobile app from scratch for our new Speech-to-Speech AI Agent offering. I created some of the core UI menus and chunks of the audio processing logic, for which I had to learn some Swift. I also built much of the auth stack for it. We ended up achieving about 1000 weekly active users within a few weeks of launch, but due to reprioritisation, we stopped work on app developement and marketing so never progressed beyond that level. A terrible shame, but a great technical learning opportunity.
  • I was involved in the project to rebuild our UI codebase from scratch, converting it from Next.js to Remix for significant uplifts in design, quality and user experience. This refactor halved the number of UI bugs and increased bug-fixing velocity substantially.
  • I had training in people management skills, which has stood me in good stead as a now-manager.

Software Engineer II

Speechmatics · 2022

I worked as a software engineer on the team which build the very early phases of the Speechmatics self-service offering. I joined just a week after the offering launched. I also had some role working on the batch transcription runtime.

Some highlights:

  • I was tech lead on a project to undertake the initial productionisation our real-time SaaS offering.
  • I built the initial UI for the real-time offering in the portal, designed the auth system, and managed the project to build out the telemetry and service management systems.

Technology Consultant

IBM · 2019 - 2022

I worked as a technology consultant for IBM straight out of university. This mostly focussed on building event-driven distributed system prototypes for the UK Civil Service.

Some highlights:

  • I did a month-long training course in management, strategy and consulting skills.
  • I earned an AWS Solutions Architect certification.
  • I did a week-long SaaS architecture principles course.
  • I worked on PoC projects to re-architect systems for departments including DWP and DEFRA, including developing decentralised event-driven architectures for cross-department systems interfacing. Most of these were not taken forward for productionisation due to the ways of working. I got bored of building things that didn’t get used which is why I left consultant for a full-fat software job!
