About Herdius:
Herdius is a Berlin based Blockchain Company. We are working on building homomorphic distributed private key generation which then is turned into value bearing products in different sectors. Currently we are very close to open beta-testing for the Herdius-Crypto-Wallet.
What we focus on on the blockchain field specifically is interoperability and trading. When connecting different chains on the key level, users can eliminate communication channels, bridges and complex systems. In other words, users can do cross-exchange and chain token swaps very conveniently and profitably for the user due to the cross-exchange arbitrage opportunities. The broader vision is one day to replace API auth keys with public-private key cryptography in order to provide layered access to user data.
All this makes for a crypto eco system and hedge fund that pays interest on all cryptocurrencies (that right now are unfortunately somewhat unusable and just laying around on wallets).
About the role:

Herdius is seeking for a Gopher Guru - an experienced Senior Golang Backend-Developer - to join our team of smart and visionary individuals. Experience in Blockchain is not necessary but a big plus.
We do not look at this role as another standard job but rather as great opportunity to build something really meaningful und amazing. Become a member of our great collective of top nodge engineers and people - altogether working to create cutting edge tech for the masses.
Besides the Herdius HQ in Berlin our Dev-Team is working mostly remote on different time-zones - so this vacancy surely also is location agnostic.
We would expect you to contribute at least 20hrs per week for part-time but joining full time is possible, too.

Utility Warehouse is a FTSE 250 organisation which has established itself as the most trusted supplier of utility products in the UK. Utility Warehouse is the only genuine multi-utility operator in the market providing gas, electricity, landline, broadband, mobile & insurance products and services to households and businesses nationwide, all on one single monthly bill. With over 600,000 customers the organisation has grown through a philosophy of offering savings, simplicity and service. Customers enjoy a number of advantages, including membership of a discount club, and a unique CashBack reward system on everyday shopping. The organisation does not advertise, preferring instead to invest in customer services and to keep prices low. Utility Warehouse has predominantly grown through a network of over 45,000 partners who operate as lead generators and advocates for the organisation. These partners come from a range of personal and professional backgrounds, and actively take it upon themselves to promote and recommend Utility Warehouse to friends, families and their professional networks. Trust between these partners and the organisation is crucial, and ensures that customer service and satisfaction are consistently prioritised.
Background
Utility Warehouse is an energetic and entrepreneurial challenger in a market traditionally composed of monolithic, slow competitors. In the utilities market, it is difficult to compete on the quality of the product and therefore establishing a strong value proposition is crucial to avoid a race to the bottom on price. Utility Warehouse has established itself as the most trusted brand in its sector, winning accolades from industry publications and consumer advisory guides. Customer service is at the core of their business ethos and another way they differentiate from their competitors; 93% of customers would recommend the organisation to a friend. By establishing a best-in-class experience for the consumer, Utility Warehouse commands a strong market position in an age where technology makes it increasingly easy to access information on consumers’ experiences. The organisation is well-placed to capture an increasingly large portion of the £52bn market that they operate in. By staying true to their values of trust and service, Utility Warehouse is the only major provider in the market to be both growing and profitable.
Utility Warehouse has an adaptive, agile, fast-paced culture which has enabled it to grow rapidly. The management team has expanded over the last two years as part of the growth strategy with significant hires in technology, legal, marketing, and finance. These hires and the rebuilding of the platform will enable the company to grow to two million customers over the medium-term. Utility Warehouse operates at high-transactional scale, processing large volumes of data. This presents new opportunities to understand customer behaviours better and to create an improved customer experience as a result.
Opportunity
With ambitious product plans for the future, it is important to have a solid foundation to enable growth for the business, allow innovation and achieve rapid time to market. To realise this, the underlying platforms and systems must be designed to be flexible, modular and resilient.
You will join our Insurance team tasked with designing and building the insurance platform from the ground up to enable new opportunities to our insurance product and services.
The platform will be a set of simple and intelligent APIs built using microservices and event driven architectures. Internally, the decision and rating engines will leverage integration with numerous 3rd party systems to provide quotes, offer addons, allow policy uptake and operational management.
