About the Role...

Permutive is looking for a Scala Engineer 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. 

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 device.. 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 we do?

We focus on enabling our customers to leverage all their owned first-party and partner data in the Permutive platform. We are responsible for the APIs and data infrastructure which our customers and partners use to onboard data into the Permutive platform. To give an idea of the scale we operate at, our Events API ingests over 100Bi events monthly, and processes over 70k events/sec at peak times.

From a product perspective, we help our customers onboard various types of data into our platform including behavioural, contextual, modelled and declared data. We also help customers connect related data within our platform, using our Identity infrastructure. The team also collaborates closely with other product engineering teams and provides interfaces to enable them to consume onboarded data and leverage it to build new product features.

What you’ll be doing?

As part of a collaborative engineering team, you will have the unique opportunity to oversee the entire development process, from conception to completion. Your responsibilities will include crafting innovative product features while demonstrating a proactive approach to coding, testing, deploying, and monitoring cutting-edge solutions. Through your contributions, you will play a vital role in driving our platform forward and shaping its future.

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, Beam, Postgres, Grafana, Terraform

What you’ll need?

  • Understanding of functional programming and general software engineering concepts.
  • Experience with Scala programming.
  • Interest in batch and stream data processing.
  • Excellent communication skills, in particular, when discussing technical concepts.

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

  • Experience with designing systems that have to operate at scale
  • Experience with messaging systems (e.g. Kafka or Kinesis)
  • Experience with distributed data stores (e.g. Bigtable, DynamoDB)
  • Experience building and deploying microservices, e.g. using Kubernetes
  • Experience with cloud platforms such as AWS or GCP
  • Familiarity with functional Scala libraries, e.g. Fs2, Http4s, Cats or Doobie
  • Familiar with stream processing frameworks, e.g. Spark, Beam, or Flink.

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 £63,750 - £75,000 + options.
