Mission

Speechify is the easiest way to listen to the world’s information. Articles on the web, documents in the cloud, books on your phone. We absorb it all and let you listen to it at your desk, on the go, at your own speed, and with tools that make learning easier, deeper, and faster.

What streaming services have done for audio entertainment, we’re doing for audio information. And whatever we’re doing seems to be working. We’re #1 in our category, and experiencing exponential growth.

• Ship cloud functions, lightweight backend services, and jobs using Kotlin

An Ideal Candidate Should Have

• Systems thinking. You know that optimizing a system requires end-to-end design, and you believe simplicity is valuable.
• Speed. You work quickly to generate ideas and options and know how to decide which things can ship now and what things need time

• Collaboration. You know how to inspire, play, and negotiate with opinionated designers, marketers, and PMs
• Preferred Tech Stack:
  • Kotlin Multiplatform (Java experience is OK but role is Kotlin Multiplatform) 
  • Prior experience with GCP is a plus

What We Offer

• A fast-growing environment where you can help shape the company and product.
• An entrepreneurial-minded team that supports risk, intuition, and hustle.
• A hands-off management approach so you can focus and do your best work.
• An opportunity to make a big impact in a transformative industry.
• Competitive salaries, a friendly and laid-back atmosphere, and a commitment to building a great asynchronous culture.
• Opportunity to work on a life-changing product that millions of people use.
• Build products that directly impact and support people with learning differences like dyslexia, ADD, low vision, concussions, autism, and more.
• Work in one of the fastest growing sectors of tech, the intersection of artificial intelligence and audio.

This role in 3 words: Amazing Security Insights

Top 3 qualities for this role: Creative, Adaptable, Technical

Where you’ll work:

Depending on the needs of your business area, we expect hub based people to be in the office at least once a week, and to go to OVO Connection events in-person. 

You’ll be assigned to the closest one of our three hub offices, Bristol, Glasgow, or London; unless your role requires field-based work. Each hub has accessible spaces to park your laptop, is designed to inspire people, help them connect and bring big ideas to life.

That's why we need diverse people from all abilities, gender identities, ethnicities, ages, sexual orientations, life experiences and backgrounds to join us.

Teamworking for the planet:

Everything we do here spins around Plan Zero. So, naturally, the team you’ll be joining plays a gigantic role in making that happen. Here’s how:

We’re hiring creators and challengers who deliver high-impact, well-engineered solutions. Every role we’re hiring puts people at the heart of our security strategy and uses technology and operational processes to build a resilient and performant business. The Path to Zero is paved with secure technology!

This role in a nutshell:

As a Senior Security Engineer (Data), you will work closely with fellow security engineers to design, build, and deploy data solutions that drive organisation-wide security value. To do this, you will build and maintain ETL/ELT pipelines and data models within data warehouses. An example pipeline being ingesting data from multiple security and technology observability tools to gather, analyse, synthesise, and develop visualisations and reporting in service of continuous improvement of security controls. 

Your solutions will enable cyber defence, attack surface and security controls engineers to proactively identify hidden problems and patterns in data and use these insights to amplify weaknesses and drive improvements to coding hygiene and system architecture. This is a great opportunity for someone who is motivated to use data to drive security improvements, and best practices across a business with wide-ranging impact, and loves working in collaborative, and supportive environments.

Your key outcomes will be:

• Help architect, design, and deploy new features, and functionality in a unified OVO security data platform to enable security engineers to optimise and automate cyber defence, attack surface and security controls assurance processes.
• Stay up-to-date with the latest security data and AI trends, tools, and technologies to ensure the team’s technical approach is innovative.
• Foster an inclusive team environment where everyone feels valued and excited to contribute.
• Communicate optimally with collaborators to explain concepts and drive informed decision making.

Within your first 3 months month you’ll:

• Gain a comprehensive understanding of our existing security data sources, data pipelines, warehouse, and security operations principles.
• Contribute to the development and enhancing of our security data and AI model architectures 
• Guide and educate other teams about effective security data and AI practices and opportunities.

Systems: Google Cloud Platform services, GitHub, Looker, Wiz, Google SecOps, Crowdstrike

You’ll be successful in this role if you…

• Data automation and AI-enablement: Develops tooling to automate security tasks (e.g. triaging, routing and tracking findings from vulnerability scanners, alert handlers, compliance monitoring and evidence collection). Can contribute to security-focused codebases. Publishes automation processes or AI tooling to code repositories or an app store. Build and maintain ETL/ELT pipelines and data models within data warehouses.
• Secure development: Able to build, test and deploy single components in a system with minimal support, and understand how the component fits into the wider architecture. Configure secure cloud environments (GCP). Can describe how code, CI/CD and cloud security posture management (CSPM) tooling works. 
• Decision support and behaviour change: Design and build decision-support and training tools that actively account for human factors. Design and develop intuitive communications, dashboards and reports that guide users toward key insights and minimise cognitive load. Analyse user interaction data to identify where decision-makers struggle and propose concrete design improvements. Proactively reframe security questions or metrics to mitigate common biases, such as presenting data in terms of both gains and losses to avoid framing effects.
• Mentor Junior Engineers: Actively mentor associate and mid-level security engineers. Provide technical guidance on security and data concepts and tools, review their work (e.g. assessment reports, proposed controls), share knowledge and experience, and support their professional development within the team.
• Community of Practice: Contribute to the security engineering Community of Practice (CoP) by leading discussions, sharing practices, offering firsthand experience to the wider community, engaging in knowledge exchange / cross-pollination to further your craft. Create content and and individually contribute to the stated successful outcomes for the CoP.
