Floworks in the press:
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%
Your Responsibilities would be to:
- Architect new and optimize existing software codebases and systems used to crawl, launch, run, and monitor the Anakin family of app crawlers
- Deeply own the lifecycle of software, including rolling out to operations, managing configurations, maintaining and upgrading, and supporting end-users
- Configure and optimize the automated testing and deployment systems used to maintain over 1000+ crawlers across the company
- Analyze data and bugs that require in-depth investigations
- Interface directly with external customers including managing relationships and steering requirements
Basic Qualifications:
- Extremely effective, self-driven builder
- 2+ years of experience as a backend software engineer
- 2+ years of experience with Python
- 2+ years of experience with AWS services such as EC2, S3, Lambda, etc.

- Knowledge of networks or/and cybersecurity
Preferred Skills and Experience
- Broad understanding of the landscape of software engineering design patterns and principles
- Ability to work quickly and accurately in a highly stressful environment during removing bugs in run-time within minutes
- Excellent communicator, both written and verbal
Additional Requirements
- Must be available to work extended hours and weekends when needed to meet critical deadlines
- Must have an aversion to politics and BS. Should let his/her work speak for him/her.
- Must be comfortable with uncertainty. In almost all the cases, your job will be to figure it out.
- Must not be bounded to comfort zone. Often, you will need to challenge yourself to go above and beyond.
