About the Role...

Permutive is looking for two Software Engineers to join us on the journey of revolutionising the way businesses leverage their data. You'll be part of a team that creates cutting-edge solutions that empower our customers to unleash the full potential of their first-party and partner data within the Permutive platform.

You'll have the opportunity to work with a wide range of technologies, tackling complex challenges and building functionality that solves previously impossible problems for our customers, to deliver measurable value through our platform.

You’ll be eager to take full ownership of the development process from start to finish, building new product features whilst showcasing a proactive approach to coding, testing, deploying, and monitoring innovative solutions that will drive our platform forward.

This is an exciting opportunity to make a real impact on the future of data-driven marketing.

Our Teams and Technologies

We’re 30+ engineers working to build an outstanding engineering culture so that everyone who joins has the opportunity and the support to do the best work of their life. Small, autonomous teams are important to us, and we want to empower everyone to make—and be accountable for—decisions through ownership.

Everything we build has to scale: our platform handles more requests each day than there are new tweets and Google searches, and each month we serve more than 2 billion user devices. We think applying functional programming techniques like compositionality and type-safety is the best way to build the type of massively distributed system our platform comprises, allowing us to move fast without sacrificing quality.

What you’ll be doing?

You will contribute to the full lifecycle of our platform, working on everything from core infrastructure to customer-facing features. This involves building scalable data pipelines and backend services, while also developing the product functionality that brings our data to life. Your work could range from creating APIs for our user interface to exploring AI-powered recommendations and automation, all while collaborating with product and engineering teams on an infrastructure that processes over 7.5 million datapoints per second.

We would love to hear from Software Engineers that have knowledge or an interest in working with some of the technologies we use:

• Scala: cats, cats-effect, http4s, fs2, circe, doobie

• Infrastructure: Kubernetes, Kafka, Bigtable, BigQuery, Flink, Postgres, Grafana, Terraform

What you’ll need?

• Understanding of functional programming and general software engineering concepts.

• Experience with Scala programming.

• An interest for platform engineering: designing and building the reliable, large-scale systems that other teams build upon.

• A strong sense of ownership, driving features and projects from concept through to production and beyond.

• Good communication skills, with an ability to discuss technical concepts clearly.

• A proactive, curiosity-driven mindset for solving problems, with a keen interest in leveraging AI tools to enhance productivity.

We'd be particularly excited if you have one or more of the below

• Some experience or familiarity with messaging systems (e.g. Kafka or Kinesis).

• Familiarity with distributed data stores (e.g. Bigtable, DynamoDB).

• Familiarity with building and deploying microservices on Kubernetes, perhaps using tools like Terraform.

• Exposure to cloud platforms such as AWS or GCP.

• Familiarity with functional Scala libraries, e.g. Fs2, Http4s, Cats or Doobie

• An interest in stream processing frameworks (e.g. Spark, Beam, or Flink) or modern data warehouse architectures (e.g. Snowflake, Databricks).

What we’re offering…

We take a structured, objective approach to salary-setting, which is based on market information, our compensation strategy, and your experience and capability as assessed through our interview process. For a typical candidate who meets our requirements, we would pay between £70,000 - £80,000 + options.

Work Your Way

Permutive trusts you to manage your time and deliver results. Our hybrid model allows you to choose where you work best, whether in your own productive space or our London (Farringdon) or New York (Union Square) offices. That said, none of us work alone; we are part of a team.

To foster collaboration and connection, teams in these locations come together in person at least once a week and are encouraged to benefit from being in our offices to meet with teams more often. Commercial and customer-facing teams are encouraged to embrace in-person interactions to build lasting relationships with clients and colleagues.

Every Permutive employee gets together in person at the company’s Annual Kick Off for a week in February. Each year’s event promises to be an exciting opportunity for us to come together, reconnect with colleagues, and align on our shared vision for the year ahead.

Diversity, Equity & Inclusion

At Permutive, we’re taking a thoughtful, intersectional, long-term approach to diversity, equity & inclusion. We care deeply about creating an inclusive work environment that allows everyone to flourish, and we are taking continual action to progress in that direction.

We’re committed to hiring people regardless of race, religion, colour, national origin, sex (including pregnancy, childbirth, and related medical conditions), sexual orientation, gender identity, age, neurodiversity status, disability status, or otherwise.
