Sr. Blockchain Engineer

Published date Posted on Indeed on Nov 25, 2021 (11 d ago)

Sila’s goal is to transform the financial landscape by creating an open-access financial network with a stable cryptocurrency at its core. We want to help developers and entrepreneurs bring their fintech ideas to market quicker and easier by incorporating compliant processes and making money programmable.

As a Senior Blockchain Engineer you will oversee the implementation of blockchain technology within our product, including writing smart contracts, evaluating new blockchains and managing the commercial blockchain application. As our business grows you may lead a team of engineers focused on blockchain technology.

Here is what you will be doing:

Blockchain Development: As a part of our team, you will collaborate to deliver, test and improve on our blockchain-integrated financial services platform. Your primary responsibilities will be creating blockchain functionality and integrating that into our business processes. Initially, you will work primarily with Ethereum (both mainnet and our private network) and Celo. You will be in charge of creating, maintaining, monitoring and improving our smart contracts.

Software Development: In addition to the strictly blockchain responsibilities, you will implement the functionality required for our systems to interact with these smart contracts. This includes submitting transactions, monitoring transactions status, monitoring on-chain events, and notifying other services of these events and outcomes. You will also work with Operations to implement monitoring and reconciliation processes on our ERC-20 stablecoin.

R & D: As a Blockchain Engineer at Sila, you will also be evaluating new and existing blockchain networks, providers and technologies for a fit within our use cases. As a part of this research, you will stay current with the latest academic and commercial news and publications. You will evaluate new solutions and propose changes when relevant.

Documentation & Training: You will be responsible for ensuring that all processes, interfaces, and systems are adequately documented for internal and external needs. Sila places a high value on mentoring and cross-training based on interest and aptitude, so you will also be involved in mentoring and building blockchain-related skill sets in other members of the engineering team.

Management & Accountability: You will be responsible for estimating effort and establishing timelines based on business requirements, as well as drafting the implementation plans for blockchain-related projects. You will be accountable for delivering based on the timeline that you specify, and will be expected to notify your manager of any changes to the timeline as the project progresses. On some projects you will also be managing work assignments for a small team and ensuring that work is delivered as specified and on time.
