MarketAxess is on a journey to digitally transform one of the world’s largest financial markets, enabling the shift from analog, phone-based trading to a fully electronic marketplace. Why does this matter? Because our platform makes trading fixed-income more accessible, ultimately improving transparency, efficiency, and competition in the marketplace. Changing the way an established industry transacts is no easy feat. There will be twists and turns, because no one’s ever done this before. But now, more than 2,000 clients around the world rely on our solutions, and that number is only expected to grow in the years ahead. We know where we’re going. How we get there is up to us. Join us and help Take Us There.

The Role

We are seeking an experienced Senior Software Engineer for our Engineering Enablement platform team. This team is building a cutting-edge developer productivity platform that will help our product development teams deliver features more rapidly and integrate code quality and security into all our products.

As a senior member of the Engineering Enablement team, you should be passionate about technology, developer experience, code quality, and evangelising software development best practices. You’ll work with the team to design and build out the platform that the rest of the company uses to deliver software, mentor more junior engineers, and help communicate what we do to the rest of the organisation.

We embrace a culture of collaboration and experimentation while striving and encouraging all team members to focus on continuous improvement and learning. We openly welcome diverse perspectives and people who are not afraid to challenge assumptions and prior ways of working. Otherwise, how do we innovate, learn and grow as a team and individuals?

  • Design and architect scalable and reliable platform solutions
  • Collaborate with cross-functional teams to understand requirements and integrate new features

What We’re Looking For

  • Minimum 3 years of experience in designing, building, deploying, and automating infrastructure using infrastructure as code (e.g., CloudFormation, Terraform)
  • Proficiency in at least one programming language such as Python, or Go
  • Strong understanding of distributed systems, microservices architecture, and cloud computing concepts (e.g., AWS, Azure, GCP)
  • Experience with containerisation technologies like Docker and orchestration tools such as Kubernetes
  • Experience in designing and implementing APIs and other web services
  • Real-work experience with DevOps practices and tools for continuous integration and deployment CI/CD systems (e.g., GitLab CI, GitHub Actions, Jenkins)
  • Proven track record of leading technical projects from conception to delivery
  • Excellent problem-solving skills and the ability to thrive in a fast-pace, dynamic environment
  • Strong communication skills and the ability to collaborate effectively with cross-functional teams
  • Experience with Agile methodologies and working in Agile teams
  • Strong knowledge of database systems (SQL and NoSQL), caching mechanisms, and message brokers
  • Expert in defining, designing, and developing distributed and scalable products and services
  • Experience with Software as a Service products and integrating multiple SaaS products

What You Can Expect from Us

  • Central Location: based at our city offices near St Paul’s.

Actual salary may vary depending on job-related factors, which may include knowledge, skills, experience, and location. You may also be eligible for annual cash incentives, equity, and other benefit programs.

Collaboration and innovation are integral to our success – it’s how we got to where we are and how we’ll maintain and grow our competitive advantage.
