Company mission
Duffel is on a mission to rebuild the infrastructure that underpins the travel industry to make it accessible for anyone who wishes sell travel.
Role
Who you are
- An infrastructure and systems engineering generalist who is comfortable diving deep into the weeds on different issues. Some recent examples include:
- A configuration issue between Google’s Load Balancer and the HTTP server in our main Elixir application causing HTTP 5XX responses to be returned to our customers
- Debugging an issue in our OpenTelemetry pipelines causing us to silently drop spans
- An enthusiasm for both software development and systems engineering
- A high bar for code and configuration quality and readability
- A good understanding of current observability and reliability practices
- Experienced and comfortable in running incident response
- Big picture thinking - you can make trade offs on technical work streams against business impact
- Fantastic communication skills. You're able to articulate what you're working on and why to the team in a clear and structured way
- You thrive in a collaborative environment. You believe in your own methods but keep an open mind, taking suggestions and feedback onboard as well
- Don’t worry if your experience doesn’t exactly align with this stack, we understand that skills are transferrable
What the job involves
- We're building tools to simplify travel distribution, search and booking
- What does this actually mean? It's one common and seamless API. This brings huge technical challenges as we need to design and build a beautiful API before integrating to hundreds of airlines
- Along with that we need to navigate through the differing needs and systems of each airline whilst building a fantastic developer experience to go with it
- As an SRE at Duffel, you’ll be part of a small team within engineering that is responsible for the reliability, performance, and resilience of our infrastructure and applications
- You will be working closely with engineering teams to understand their needs and help meet the demands of our product as we scale globally
- We run our infrastructure on Google Cloud Platform, so you’ll be helping to run a few of their products such as GKE, CloudSQL for PostgreSQL, BigQuery, Memorystore (Redis) and more
- We manage the infrastructure and security for a segregated PCI Cardholder Data Environment, entirely managed with Google Cloud Platform services and tooling
- We follow an Infrastructure as Code approach to managing our infrastructure, using Terraform
- We follow a GitOps approach to managing our Kubernetes configuration, using ArgoCD and Helm
- We manage a high-availability metrics collection system using Grafana, Thanos & Prometheus. We’re in the process of transitioning to OpenTelemetry and Honeycomb for our application telemetry (traces and metrics)
- We manage a data pipeline using Pub/Sub, Airbyte, and dbt
- We’re currently driving a big shift in how we think about and monitor reliability across the engineering organisation, with a focus on early detection of customer-impacting issues
- We’re extending and standardising our use of OpenTelemetry, and introducing Honeycomb as the single place for engineers to understand how our applications are operating in production
- This project involves both technical work, on the application libraries and infrastructure that make up the OpenTelemetry pipeline, and an education piece, working to change perceptions and behaviours across engineering
- We currently run all our services from a single European region in Google Cloud. In the medium term, for performance, reliability, and data residency reasons, we’ll be starting to think about how to (re)architect our applications and infrastructure to span multiple regions, operating globally
- We deploy our application multiple times a day, but deploys are all or nothing, and when we encounter issues, roll backs are slow
- One way to address this would be to invest in CI/CD performance improvements, but we’d also like to explore alternative deployment strategies like Canaries, Blue/Green, and traffic mirroring, and get more comfortable testing changes in production with real customer traffic
Salary benchmarks
Our take
In the same way that challenger banks have come along to re-invent legacy banking software from the ground up, Duffel is doing the same in the travel market, linking up airlines directly with travel agents with a modern platform.
Duffel's system connects with airlines’ booking channels more extensively than those of incumbent operators, like Amadeus and Sabre, meaning it can facilitate selling not just seats on a plane, but also other products such as speedy boarding, airport transfer and seat selection.
Add-on products make up an increasing part of airline revenues but are mostly sold through airlines' own websites at the moment (whereas bookings are increasingly being made via intermediaries like Skyscanner). Duffel's technology will make it easier for airlines to sell more of these ancillary services, which is what makes its product so attractive to airline customers.
Duffel's main competitor in Europe, Amadeus, has several billions in revenue and over 15,000 employees, so there's a big challenge ahead, but a big prize if the company succeeds in capturing some of that market.
