What will be your key responsibilities?

Although it’s an engineering role, you will have significant involvement in product, hiring and business as well. You may expect following key responsibilities:

Engineering: You’ll need to write code – a lot of code. At the end of the day, your most important responsibility is to get your company’s product to market and maximize the number of product experiments that can be run. You’ll make key architectural decisions that will be pillars of the engineering organization for years to come. At the same time, you’ll have to make serious trade-offs to balance speed of execution with quality.

Product: As a founding engineer, you’ll also have a significant amount of ownership over the product direction. You should expect to spend time talking to customers, teasing out use cases, and making prioritization decisions regarding both the short- and long-term roadmap. In many cases, you will be building features in the absence of any formal product requirement document.

Support: You should also expect to spend a fair amount of time in the trenches supporting customers. You’ll probably find yourself engaging with customers in shared Slack channels, WhatsApp groups etc.

Hiring: As a founding engineer, you will spend a ton of time sourcing, interviewing, and closing early team members. 

Business: Finally, you’ll gain exposure to all other aspects of the business – from fundraising, to sales, and beyond. Although you probably won’t be closing deals or making pitch decks, you will certainly be expected to sell your product and pitch the company’s vision.

How do you know you are right fit for the role?

• You have at least 2-4 years of experience. You are proficient with most of the following languages/frameworks:
• NodeJS
• AWS
• Databases (both SQL and NoSQL)
• You crave ownership. If you often find yourself raising your hand to own things end-to-end, you will likely really enjoy the ownership afforded to you as a founding engineer.
• You’re okay with ambiguity. You won’t get product requirement documents or designs for everything you’re expected to build. A stellar founding engineer will know when to ask for clarity and when to make educated assumptions. If you tend to gravitate towards more loosely scoped projects, that’s a good indicator that you’ll do well in this type of role.
• You’re multidisciplinary. A typical day might include anything from several hours of coding, to a few customer conversations, to a technical brainstorm or architecture discussion, to an interview or two. 

• You operate at light speed. A great founding engineer should welcome this challenge and thrive under the pressure of intense deadlines. 

What will be the hiring process?

• 2 round of technical interviews
• 2 round of behavioural interview

What will be your compensation?

• Fixed: INR 20L-30L
• Bonus: 10-30% of Fixed depending upon performance.

• Equity: 0.1%-0.2%

As a senior software engineer, you will contribute to our end-to-end supply chain platform. You'll work with all key stakeholders to deliver scalable, maintainable backend code and work with frontend developers to deliver amazing user experiences.

You are:

• A self-starter with a sense of what it takes to be successful as a team
• An agile - welcome change, do as little as possible and embrace continuous delivery
• Conscious about how quality is carried through from the UI to all layers underneath
• Opinionated, but flexible to accommodate the big picture

Responsibilities

• Analyze requirements, provide estimates and deliver code in an agile setup
• Stay on top of all owned work and raise red flags as early as possible
• Define the architecture, best practices, and coding standards

• Motivate team members, coach junior members, and extend goodwill to other employees

Job Summary:

• Willingness to work on highly scalable cloud-native solutions based on microservices.
