We're seeking an exceptional software engineer to join the small and very enthusiastic data and recommendations team at Last.fm. The position is full-time and based in London.
Are you ready to tackle all the challenges that high-performance, data-intensive backend software can put on your way? Do you like thinking about cache lines, memory bandwidth, seek times, and how code constructs are compiled into machine code? At the same time, do you enjoy writing lean, tested, modular code, using the kind of high-level and expressive idioms only Boost and the STL can offer? Do you have experience implementing key-value stores, information retrieval or large-scale machine learning software?
We need a coding wizard to help develop last.fm backend infrastructure, where magic like recommendations, tag clouds, radio playlist or realtime profile charts generation happens.
- Analyze, test, optimize, maintain, design and build core backend software components
- Perform research on algorithms for recommendation and scalability related problems
- Build cool demos with our data
- Code using primarily C++ (STL/Boost) and Python
- Expert knowledge developing and debugging in C++ on *nix
- Experience building large-scale server applications
- Interested in: computational complexity, scalability, map/reduce, bloom filters, bitmaps, caching algorithms, multithreading, radix trees, LSH, template metaprogramming, thrift, boost, bogosort, and much more
- MSc in computer science or related is a plus
Purpose & Background of Role
We're seeking a top notch data scientist with strong programming skills to join the data team at Last.fm. This is a full-time position, based in London.
Are you an experienced scientist as well as a hands-on implementer who is able to work around constraints in disk speed, memory size and CPU cycles? Do you want to help design, implement and evaluate playlisting and recommendation algorithms that reach millions of music lovers each month? Do you take pride in being clever and solving difficult problems creatively? Are you full of ideas and always looking for new ways of making use out of data? Are you an advocate for data-driven development and fully capable of conducting a proper A/B test?
The data team works with large volumes of audio (millions of tracks), user data (tens of billions of scrobbles), and metadata (7,593 different spellings of Britney Spears). We run data processing and analysis jobs on our own Hadoop Cluster, and write and maintain scalable realtime services including several recommendation and playlisting engines. We encourage publication of research results and contribution to open source projects.
We're looking for a talented and enthusiastic scientist to help us explore and learn from our rich datasets, build services and infrastructure, conduct data-driven evaluations and experiments, improve our recommendation and playlisting services, and help drive innovation in our website, API, client and mobile applications.

You are a technology leader with experience managing agile development teams (preferably using Scrum). You have experience architecting large-scale systems and love writing code. You really understand scalability and performance. You're comfortable working with technical, product & commercial teams, from very senior to very junior people and everyone in between.

- API design
- Last.fm (being a user of the site doesn't hurt ;) ).
- Foosball or retro arcade games.
You will be part of a team that likes to deliver well thought-through and measured features each sprint. We think that everyone should be hands-on and there are opportunities to tinker and build across the whole stack, from back-end to front-end, as well as to solve interesting interaction problems. We collaborate closely with everyone in the company - product, design and support, through to the infrastructure and commercial teams. We also collaborate closely with each other - we like to design things, review each other’s work and share techniques as a team.
* prototype then build features, working together with the design and product teams.
* build responsive, accessible features that work across multiple platforms.
* work on a user-facing product used by millions of people
* hack on things and not be afraid to innovate to get the job done.
* improve existing journeys on the site, with a user focus.
* maintain and update style guides as new interface problems are solved or designs changed
* have many opportunities to be inventive, and have your ideas expanded into full features.
* hone your skills by drawing on the strengths of your colleagues.
* learn about and solve the unique problems that come with a website that operates at such a large scale, such as performance, A/B testing, service architecture and lazy-loading.
* gather hard evidence to support your ideas
* a professional with 5+ years experience
* willing to tackle the hard problems first
* proud to work to a high standard
* able to put yourself in the shoes of many different users
* not afraid to change your mind when the evidence leads to unexpected conclusions

* enough Linux experience to get by.
* experience with version control (Subversion / Git)
* a passion for music
As a bonus, perhaps you also:
* feel comfortable with Test Driven Development
* have a keen eye for graphical and/or interaction design
* know how to conduct user testing sessions
* know how to set up effective experiments in Google Analytics
* have worked with mobile apps or other non-web interfaces
* are good at Juggling, or perhaps Trapeze
When will we hear from you? How about right now?
