Crypto-currency & Security Wizard: Maple Ridge, BC

We’re looking for a key person with similar core values as us, which means you want to positively change the world too! You believe that a mesh platform can be a key enabler of distributed financial transactions and want to be a game changer in that space. We are in need of an expert in crypto-currency and security systems looking to work with the next generation of mesh networks. You are highly technical, deeply analytical and not many speak your language. But we admire that about you. You thrive in a culture that isn’t afraid to try new things (maybe fail once or twice) and challenge the status quo.
If you haven’t heard of Left before, we’re a technology company based in the suburbs of Vancouver in Maple Ridge. Our award-winning Community Engagement Program and our top-notch culture have led us to win an award as “Best Workplace BC” and be recognized by the BC Tech Association as the best in BC for “work, life, and play”. At the heart of our business (what you’ll be working on), we’re building a platform to connect the next billion people without infrastructure using a fully-distributed mobile mesh network for Android and iOS mobile phone platforms, along with IoT devices. Since this mesh platform is a distributed, decentralized communications tool (this is where you come in) — it is a natural fit for decentralized ledgers and blockchain types of technologies. We can hardly hold in our excitement about using both as a means to enable real-world financial transactions, but also to establish trust between devices and account for whether or not a device is behaving as expected in the mesh.
Where does all this magic happen? We might have the coolest office space in the Lower Mainland (BC), complete with a games room, library, lots of beer, and a plenty of silly people. We are purposefully located out in the ‘burbs so that our employees can live and work in their community. If you do commute, it’s only 40 minutes against traffic from downtown Vancouver, and we’re just across the Golden Ears Bridge, so we are extremely convenient for all the talented people in the Fraser Valley. And speaking of sky-high real estate prices, you actually have room to breathe out here and can afford to exhale. Are you ready to change the world yet?
About the Job: So, what will this role involve?

  • Working with a team of world-class technical rock-stars to design, develop and integrate your knowledge into existing projects and help build the core communications technology.
  • Utilising your expertise to integrate established blockchain or cryptocurrency related APIs and libraries into our codebase and/or creating new implementation specific to our codebase.
  • Live, eat and breath security through: brainstorming, whiteboarding, design, documentation & implementation of potential security, trust, and encryption mechanisms within our library.
  • Identify and select existing libraries, integrating them as well as develop new code.
  • Find comfort in making whiteboard presentations, defending ideas, and being challenged by an engaged and passionate team.
  • Come on, you know you want to audit our existing code too, right?
  • Play (more professionally known as “build”) and test proof-of-concepts, evaluating their performance and documenting the process.
  • Ensure all code is stable, secure and developed in a way that makes it easy for both 3rd party developers and end users to use and deploy.

Essential Skills: What do you need to get here?

  • You’ve woven your passion into earning a Bachelor’s Degree in CS, Computer Engineering or other related fields.
  • Experience with Java, our language of choice.
  • Experience with Android Studio, Git, Unit-testing, deploying apps on Android & iOS.
  • You can passionately explain the inner working of various encryption and security schemes, identify their strengths and weaknesses, evaluate the performance and implement them.
  • You have proudly developed and released APIs/libraries that are used in other projects.
  • You have developed P2P and decentralized applications, contributed to the networking and security.
  • Your understanding of blockchain and cryptocurrencies can confuse mere mortals.
  • You are happy to show us your contributions to open source and can provide git repositories with contributions.
  • You learn new concepts fast and through your ability to communicate with highly-technical material and experts.
  • You have high expectations of yourself and others because you believe the impossible is possible.
  • Your communication skills (oral, written, and with other cultures) are one of your many assets.

Useful things:

  • You have taken it to the next level by earning an M.Sc. or Ph. D in Computing Science, Computer Engineering or other related fields and published papers in cryptography, security, encryption, cryptocurrencies, blockchain, and/or distributed ledgers.
  • Experience with C/C++, Objective-C developer.
  • Development experience with Corda or other distributed ledger technologies.
  • Undeniable technical skills in Solidity, Go, and Node.js.
  • Your wizardry is already in practice because you’ve actively contributed to fundamental parts of an existing blockchain or cryptocurrency project.
  • Because you think outside the box [or insert other buzz word here], you have experience developing Ethereum, Bitcoin, blockchain, or other cryptocurrency technology on devices.
  • You have experience porting libraries to mobile environments.
  • You have experience with traditional web architectures (client/server, databases, web backends).
  • You have created some original implementations, and thus may have patented or licensed under creative commons, some methods or mechanisms related to security and encryption.
  • Experience as a developer or security evangelist.
  • You show your love for teamwork through participation, mentorship, or coaching in hackathons or coding challenges.
  • Knowledge (and willingness) that sometimes it requires we work around the clock – not because someone is poking you with a sharp stick, but because we want to and we realize that we can build something of real and lasting value.


  • You are entrepreneurial. This means you know failure is an option, but you also know that when you learn from failure, this is often when the impossible becomes possible.
  • We still classify ourselves as a start-up even though we are an international office of 95+. We currently have about 35 in Maple Ridge and 90+ in Bangladesh, so you must want to be in the start-up environment. Your decisions matter.
  • Maybe you have worked in a senior technical role already, or maybe you are just finishing up your Ph.D. and can’t wait to dive into the real world, but in any scenario, you wish to be part of a smaller team where you would have a direct impact on the business as a whole.
  • You must be a self-starter and able to take initiative and manage your own projects.
  • You can self-learn as things change; and quickly, because learning must be ongoing and things change often.
  • We are Dog positive; Django is our Director Of Greetings and he outranks most of us.
  • You must believe in the mantra of “Work hard, play hard.”
  • You must be able to laugh at yourself and roll with the punches.
