tl;dr If you’d like a job with us, send your application as soon as possible.
We are looking for several (probably two) Haskell experts to join our team at Well-Typed. This is a great opportunity for someone who is passionate about Haskell and who is keen to improve and promote Haskell in a professional context.About Well-Typed
We are a team of top notch Haskell experts. Founded in 2008, we were the first company dedicated to promoting the mainstream commercial use of Haskell. To achieve this aim, we help companies that are using or moving to Haskell by providing a range of services including consulting, development, training, and support and improvement of the Haskell development tools. We work with a wide range of clients, from tiny startups to well-known multinationals. We have established a track record of technical excellence and satisfied customers.
Our company has a strong engineering culture. All our managers and decision makers are themselves Haskell developers. Most of us have an academic background and we are not afraid to apply proper computer science to customers’ problems, particularly the fruits of FP and PL research.
We are a self-funded company so we are not beholden to external investors and can concentrate on the interests of our clients, our staff and the Haskell community.About the jobs
One of the roles is for a specific project with one of our clients, and requires work on-site in London. The other role is more general and not tied to a single specific project or task, and allows remote work.
Please indicate in your application whether on-site work in London is an option for you.
In general, work for Well-Typed could cover any of the projects and activities that we are involved in as a company. The work may involve:
working on GHC, libraries and tools;
Haskell application development;
working directly with clients to solve their problems;
teaching Haskell and developing training materials.
We try wherever possible to arrange tasks within our team to suit peoples’ preferences and to rotate to provide variety and interest.
Well-Typed has a variety of clients. For some we do proprietary Haskell development and consulting. For others, much of the work involves open-source development and cooperating with the rest of the Haskell community: the commercial, open-source and academic users.
Our ideal candidate has excellent knowledge of Haskell, whether from industry, academia or personal interest. Familiarity with other languages, low-level programming and good software engineering practices are also useful. Good organisation and ability to manage your own time and reliably meet deadlines is important. You should also have good communication skills. Being interested or having experience in teaching Haskell (or other technical topics) is a bonus. Experience of consulting or running a business is also a bonus. You are likely to have a bachelor’s degree or higher in computer science or a related field, although this isn’t a requirement.Offer details
The offer is initially for one year full time, with the intention of a long term arrangement. For the remote role, living in England is not required. For the on-site role, you have to be allowed to work in England. We may be able to offer either employment or sub-contracting, depending on the jurisdiction in which you live.
If you are interested, please apply via firstname.lastname@example.org. Tell us why you are interested and why you would be a good fit for Well-Typed, and attach your CV. Please indicate whether the on-site work in London is an option for you. Please also indicate how soon you might be able to start.
We are more than happy to answer informal enquiries. Contact Duncan Coutts (email@example.com, dcoutts on IRC), Adam Gundry (firstname.lastname@example.org, agundry on IRC) or Andres Löh (email@example.com, kosmikus on IRC) for further information.
We will consider applications as soon as we receive them, and will try to fill the positions as soon as possible. In any case, please try to get your application to us by March 27, 2016.
After some feedback on my previous post I ended up with the following implementation.instance FromJSON V.VersionRange where parseJSON = withObject "VersionRange" go where go o = V.thisVersion <$> o .: "ThisVersion" <|> V.laterVersion <$> o .: "LaterVersion" <|> V.earlierVersion <$> o .: "EarlierVersion" <|> V.WildcardVersion <$> o .: "WildcardVersion" <|> nullaryOp V.anyVersion <$> o .: "AnyVersion" <|> binaryOp V.unionVersionRanges <$> o .: "UnionVersionRanges" <|> binaryOp V.intersectVersionRanges <$> o .: "IntersectVersionRanges" <|> V.VersionRangeParens <$> o .: "VersionRangeParens" nullaryOp :: a -> Value -> a nullaryOp = const binaryOp f [a, b] = f a b
Thanks David for your suggestions.
