Smart Contract Developer

About Wintermute

At Wintermute our mission is to enable, empower and advance the truly decentralized world for more transparent and efficient markets and products.

Wintermute is one of the largest algorithmic trading firms in digital assets globally. We manage billions in assets and trade more than $5B+/day across dozens of different trading platforms. Wintermute provides liquidity algorithmically across most CeFi and DeFi exchanges and via OTC. Wintermute was one of the earliest adopters of DeFi and is a big supporter of decentralized finance. We are widely known to be one of the largest and most advanced liquidity providers in DeFi. We support all major DEX, trading platforms, AMMs, RFQs, aggregators and we work with most major chains. Wintermute is an official market maker for many of the most prominent blockchain projects and we actively support the DeFi ecosystem: we invest in and help scale early stage DeFi projects, we actively participate in governance of various protocols and cooperate with projects of building the missing pieces of the ecosystem. Wintermute is a hyper-growth highly profitable business with a very ambitious vision and roadmap. We are backed by Lightspeed, Pantera Capital, Sino Global Capital, Blockchain.com Ventures, Avon Ventures by Fidelity Investments, DeFi Alliance and other top tier investors. We are run as a technology company, not a financial service provider, and we build our culture around core values of ambition, collaboration, entrepreneurship, transparency and meritocracy.

Working at Wintermute DeFi team

We are looking for a smart contract developer to design/build secure and reliable dApps in Solidity. You will get a lot of independence and responsibility right away, and you’ll learn at an unprecedented speed! A great advantage of this position is that it is varied and it is also up to you to shape it in the direction that matches your talents and company needs.

Responsibilities and projects may include:

• Design/implement secure and reliable applications in Solidity
• Collaborate with full-stack, front-end developers and quantitative developers to bring products to life
• Development of automated testing code bases and audit of smart contracts
• Providing tech support internally for optimal execution of trading strategies
• Researching dApp protocols and providing a vision for the space
• Optionally, longer term researching/developing rust smart contracts

Hard skills requirements

• Deep understanding of EVM, solidity, and popular decentralized protocols
• Programming fundamentals in e.g. C++, Python Java; OO, design patterns, etc.
• Blockchain fundamentals: consensus, nodes, miners, forks, transactions, web3
• 2-3 years development of smart contracts and working on DeFi projects and protocols is an advantage, but if you are a self-taught genius or a DeFi enthusiast working on own projects, that may work too
• Knowledge and experience of test-driven development
• Familiar with the common smart contract vulnerabilities (we will test!)

Nice to have skills

• Knowledge of other chains (Solana, Polkadot) is an advantage
• Trading knowledge isn’t required but curiosity to learn algorithmic, quantitative, market making trading would be a huge plus, as well as understanding of DeFi native trading (farming, liquidity mining, liquidations, etc)

Culture fit requirements

• Love coding, love problem solving, building things and seeing your products work
• Curious about algorithmic trading and financial markets
• Determined, ambitious yet humble, willing to work hard, give and take feedback
• Like meritocracy and being judged by what you deliver
• Owner mentality: focused on doing what it takes to achieve important results, prepared to work non-standard working hours, no 9-to-5 mentality
• Like working in a team environment closely collaboration both within and outside the team

Wintermute offer

• A unique opportunity to work on very interesting projects, get the level of responsibility and ownership that would be unlikely at any other project or trading firm
• A unique opportunity to join one of the strongest and most successful DeFi teams globally
• With Wintermute you don’t make a bet on a single product, platform, chain or technology; we’ll win if DeFi wins as a whole
• Great company culture: informal, non-hierarchical, ambitious, highly professional yet collaborative and entrepreneurial
• Option to work from London or Singapore offices, as well as remotely; we generally prefer at least 60% working from the office but are open to remote candidates
• Weekly team events, such as team lunches, team dinners, team board games and Dota playing sessions; these are not obligatory in any sense, but this is what we like to do
• Aligned incentive structure: high upside from performance-based variable pay with very transparent bonus system
• We offer standard perks too, like pension, private health insurance, free food and office gym, but that’s probably not the right reason to join us
• We offer UK work permits and help in relocation; we prefer Singapore candidates who have PR or citizenship but are able to arrange permits too for the best candidates

Tips for successful application

• Only apply to us if you are genuinely interested or curious about this role and DeFi space; this is not for someone who is just looking for “a job”
• Do some research: look at our website and social media channels
• Write us a short, honest, and direct message if you’d like to apply. Tell us about why you are interested in DeFi in general and in Wintermute in particular. Do not send us generic copy paste applications, we are looking for authentic people who share our interests, values and ambitions!
• If you don’t have an obviously matching experience or skills, make sure you state very clearly what you can bring or how your experience is relevant (but note, we do require deep blockchain development expertise)
• Prepare to be tested on your blockchain knowledge. We do not care as much about your credentials (university or prior employer), but we care a lot about your knowledge and ability to get things done
• Unfortunately, we won’t be able to proceed if you simply press “submit button”; we do promise to reply to everyone who puts time and effort in making the application relevant!
