Permutive is looking for an enthusiastic and curious Software Engineer who is excited to work and learn alongside our experienced Publisher Audience team.

Once up to speed here with the tools and technologies, you will use a wide range of approaches to build the functionality that solves previously-impossible problems for our customers and helps them deliver value through our platform.

You will join a team of experienced engineers who own the process of building new product features and managing the whole development process, including design, coding, testing, deploying, and monitoring.

The Team and Technologies

Publisher Audience Team help our client to extract value from their data by building Cohorts, Cohorts are groups of user grouped by 1st Party data. We are responsible for maintaining event processing pipelines that process billions of events every single day, build HTTP services that are scalable and robust and developing infrastructure to allow our Data Scientist to work efficiently.

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, fs2, http4s, circe, doobie
  • Infrastructure: Kubernetes, Kafka, Bigtable, BigQuery, Beam, Postgres, Grafana, Terraform, TensorFlow, Cloud Run

The Role

You will be responsible for helping the team to build out new services and processing pipeline, and ultimately to drive business value to our customers.

The wider context

Permutive is a B2B SaaS company building the data platform and tools for a world with a trillion edge devices. We have product–market fit and customers that love us, and we’re 90+ people and growing rapidly in Europe and the US. We have received funding from some of the world’s best investors, including Y Combinator.

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 see more than a billion users. We think applying functional programming techniques like compositionality and type-safety is the best way to build the type of massive distributed system our platform comprises, allowing us to move fast without sacrificing quality.

The ideal candidate will have

  • Understanding of functional programming and general software engineering concepts
  • Some experience with Scala programming.
  • Some experience with distributed system and understand when to use them.
  • Able to communicate technical concepts clearly.
  • Excellent communication skills.

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

  • Familiarity with Apache Kafka or similar messaging system
  • Familiarity with functional Scala libraries, e.g. Cats or fs2
  • Familiarity with microservices, e.g. using Kubernetes
  • Experience with cloud platforms such as AWS or GCP


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 candidate with commercial experience working with Scala plus our requirements we would likely pay £70,000 + options.

For a candidate with commercial Scala experience, who meets several of our bonus criteria, we’d pay up to £100,000 + options.


  • Stock options
  • Parental Leave Policy entitling new parents up to 26 weeks of leave on full pay
  • Everyone has an annual learning budget of £2,400 which we encourage you to use to level up
  • Time to rest and relax with unlimited paid leave (minimum expectation of 25 days annually)
  • Extensive training and development opportunities
  • Automatic enrolment into our pension scheme from day one
  • Free access to Spill, our mental health partners

Diversity, Equity & Inclusion
