Job description

About 9fin

The world's largest asset class, debt, operates with the worst data.

Technology has revolutionized equity markets with electronic trading, quant algos and instantaneous news. However, in debt capital markets, the picture is completely different. It still behaves like it’s in the 1980s; trillions of dollars of trades are placed over the phone, news is slow, and corporate credit information is imperfect and scattered.

Our mission is to change this.

9fin's proprietary technology delivers fast and comprehensive financial, credit, legal & ESG analysis. Our clients are able to make faster, more informed decisions, win more business and most importantly, save time.

Our fast growing list of clients include 9 of the top 10 Investment Banks, leading Asset Managers, Hedge Funds and Law Firms.

The Opportunity

We are looking for a highly-motivated and driven platform engineer, with experience in enabling a DevOps culture within tech teams. In this role, your primary responsibility will be to provide a world-class developer experience to other engineers. You will have the autonomy to build solutions for the fascinating problems that we have to solve, allowing our customers (the software engineers) to build products quickly, securely, and to a high standard of quality.

Every day is different, but here’s an example of the kind of things you’ll work on:

• Designing and implementing high quality infrastructure as code templates/modules, and empowering software engineers to use them for their projects.

• Implementing AWS multi-account core infrastructure, and ensuring security best practices are being used across the cloud estate.

• Authoring CI/CD templates and optimisations to ensure that engineers can release as early and often as possible.

• Designing and implementing a developer portal (eg. Backstage), to provide a service catalog to the engineering team, and also author many other useful DevOps plugins.

• Contributing to observability best practices and providing key SLI/SLO metric reporting, so that the engineering team can balance velocity and reliability.

• Develop inner/open source projects to help provide a world-class developer experience to the engineering team.

About You

This role will be a great fit if you:

• Good working knowledge of AWS services including ECS, EC2, Lambda, VPC, IAM, Route53, CloudFront, S3, RDS

• Good understanding of monitoring and logging solutions, e.g. Prometheus, AWS Cloudwatch, Grafana, OpenTelemetry, Honeycomb, ELK etc.

• Basic SRE knowledge, and experience in alerting and incident management platforms (eg. Opsgenie, Pagerduty)

• Proven ability to provide and support strong and scalable CI/CD pipelines

• Linux, Git, Docker and good scripting skills in e.g. Python, bash, Go. You should be proficient in at least one modern programming language.

• Good experience in defining Infrastructure as Code, using Terraform or Serverless etc.

• Knowledgeable and comfortable with Agile development practices

• Great appetite for learning and self-improvement

• A real passion for developer experience, as well as an understanding and enthusiasm for Platform Engineering as a discipline

• Previous experience in fintech is a bonus

Our Benefits

We’re a scaling start up and we enjoy sharing our success, when the company succeeds, we always reinvest that in our people. We also offer huge amounts of responsibility, an abundance of opportunity for growth and a platform to truly excel.

• Salary: competitive + equity options

• Holidays: 25 days per year (plus local public holidays)
