About Us Letterdrop is a YC-backed seed stage startup. We help sales-led companies uncover net new pipeline by finding signals in conversations (on the web, in your CRM, on calls, etc) and automating intelligent outbound and nurture through effective social selling. Most businesses are using AI to create more spam, but selling is relationship driven. We give sellers the tools to automate the tedious tasks and become data-oriented about building relationships. You’ll be working directly with me, the CEO to design and build features.
Our customers include fastest growing mid-market startups like Clay, Crossbeam, Gem, Synthesia, as well as enterprises like Fluke and Mountain. More well known logos we can’t share.
We are break-even, have more pipeline than we can handle, and growing.
About You Need three things in this role:
You understand memory, parallelization, and runtime from a practical standpoint. You don’t create arrays with 60,000 elements and wonder why you’re running out of memory. AI tools make you faster, but you still need to know what good code looks like.
You take pride in clean, maintainable code. You work well on a team. You read others’ code. They read yours. Make both of your lives easy by keeping things simple. If you’d hate reading your own code in 6 months, rewrite it. 2. You are hungry and eager to build to ship great product fast You move fast. We’re a startup. Expect to ship multiple bug fixes, improvements, and features per week. Speed matters, but so does stability.
You are independent and learn quickly. Everything you need is online - documentation, GitHub issues, open-source code, spoofing network requests, and AI is there to help you along the way if not do it outright for you. You can navigate it without handholding.
You have product taste and care about building great product experiences. Our product is used by sales and marketing teams at fast-growing companies. If they run into bugs, poor UX, latency, or crashes, that reflects poorly on us. You want people to use our product and go “Wow!”
Software engineering as we know it from 12 months ago obsolete. You know how to use the latest tech to be effective and can prove it. This isn’t about knowing how to prompt ChatGPT. You’ve internalized AI into how you work. You use Cursor, Claude Code, or Devin daily and know how to hand off as much as you can to them to get stable maintainable working code out. You’ve experimented with AI for design exploration, writing PRDs, generating test cases, perfecting frontends, and automating the boring parts of engineering. You have opinions on when AI helps and when it gets in the way. Most importantly, you can bring this mindset to a team and raise the bar for everyone, not just yourself.
