About Oku

At Oku, we aim to close the gap between the CeFi and DeFi trading experiences. It is no mistake that 95% of crypto trading occurs on centralized platforms like Binance and Coinbase since their organizations have spent substantially more time and resources investing in their trading interface, while DeFi has primarily been focused on infrastructure and protocols for the last several years.

However, that is going to change soon. While CeFi organizations enjoy their Web2 stack, a Web3 company like Oku can leverage the composability of the DeFi ecosystem and blockchain technology to offer a high-quality trading experience that will eventually be indistinguishable from CeFi and, in the long run, overcome their legacy systems. That is why Oku has 50+ partners in or supporting the app.

Oku initially started as a project within GFX Labs after they received a $1.6M grant from the Uniswap Foundation in October 2022 to build and launch a reimagined trading interface, analytics platform, and API for Uniswap v3. After ten months of development, Oku launched in July 2023, and since then, Oku has supported the DAO Uniswap’s efforts to expand across new blockchains.

Today, our primary feature is our smart order routing system, which integrates 12+ order routing systems to ensure all users find the best price possible. We have also adapted our order routing technology to offer a bridge aggregator with 11+ integrated bridges. Most recently, to close the CeFi/DeFi gap further, we added on/off-ramping with USD and EURO to our interface at an industry-low fee of free! Our other popular features include trustless onchain limit orders built directly on Uniswap v3, our position manager page for users who want to manage their LP positions, and our Uniswap v3 analytics.

Over the coming years, Oku will be expanding the scope of our offering and improving the quality of our user experience.

Why work at Oku?

• Any firm can pay a high salary and offer good incentives (as will we), but most can’t offer interesting, challenging, and rewarding work.
• We have something to prove. Our team is young and hungry. We like to move fast and make things. We know when to double down and when to cut our losses. We are going to make mistakes, and we are going to build a better product because of them. We don’t micromanage or have a huge team of product managers. We want self starters who take charge and solve problems.
• We don’t care if you went to school, what grades you got, or your age. Show us what you have built, what problems you have solved, and what skills you have.

About the role

About the role

Join the integrations team as a software engineer on the CoinLedger platform which currently processes hundreds of millions of transactions every year spread out across 300+ centralized exchange integrations. Supporting such a significant number of integrations is a large undertaking and will require working with large amounts of data and external APIs in order to maintain the quality ours users expect.

Your responsibility will involve collaborating with a team of 3-4 other software engineers to build brand-new integrations for the CoinLedger platform, improve the functionality of our existing integrations, and help the team operate more efficiently.

• Improving import infrastructure to enable real-time transaction syncing from crypto exchanges
• Building robust monitoring systems to react to breaking changes from crypto exchanges
• Building new workflows for enabling realtime balances to be fetched from crypto exchanges to assist users with reconciling their transaction history

This will be an extremely high impact, challenging role in a fast paced environment. However, you will have the opportunity to shape the direction and deliver high-impact changes within CoinLedger from the ground up.

We hope you are up for the challenge.

About you

• You have 1-3 years experience as a software engineer working on backend systems
• You have worked professionally on a C# / .NET codebase
• You are able to strike the balance between speed of delivery with quality of development
• You are comfortable working closely with members of our support team in order to help resolve issues and improve the import experience
• You have experience working with engineers at different levels and have coached them in their career development.

In the first month, you will:

• Work closely with the team lead to get onboarded into the CoinLedger engineering org
• Deliver multiple improvements and bug fixes to our existing integrations
• Build a new file-based integration for processing transaction history on a CSV/Excel file
• Identify and document areas of improvement in our existing processes.

Within the first 3 months, you will:

• Build and launch a new API-based integration with a crypto exchange
• Have shipped multiple high-impact improvements to our importers
• Become a pivotal player in the core integrations team.

What success looks like:

• You are diligent in your day to day work when processing transaction history for our users
• You are able to be self-accountable in a remote-work environment
• You are a self-starter and are able to jump into technical problems when they come-up
• You push the pace to improve
  • Development velocity of new integration launches
  • Time to recovery when integrations break
  • Development velocity on new features
• You help identify problem areas in our current process and implement improvements which will:
  • Make the import experience better for our customers
  • Make the development & debugging process better for the whole integrations team
