Senior/Staff Engineer (Backend Focus)

Build features/infra for Readwise, Readwise Reader, and our new (secret) product. Designing the APIs, data models, and backend systems that power our web, desktop, iOS, and Android apps.
Tackle hard backend problems: building reliable ingestion and sync pipelines that move huge amounts of data, scaling our Postgres database (20TB and growing), integrating with dozens of external reading services, and keeping the whole system fast as we grow.
Take on staff-scope work when you want it: leading architecture rewrites, owning cross-cutting platform decisions, or shaping our internal LLM/agent infra. There's no shortage of meaty problems for engineers looking for them.
Our developers operate with extreme autonomy: you'll own new features, abstractions, infrastructure all the way from planning to building to shipping.

Reader & Self-Learner — Everyone on our team is genuinely passionate about what we're working on and we hope you are too ;)
Senior Engineer (or above) — You have at least a few years of shipping backend/infra code into production
- Experience with Python, Django, Postgres, Redis, Celery, and large-scale data systems a huge plus.
Available US or EU Hours — We're distributed across America and Europe, so your working hours need to overlap meaningfully with your teammates.
Agentic Engineering — Our engineering team has leaned heavily into using agents to ship higher quality code at a faster cadence.
- Not vibe-coding or slop, but rather applying LLMs (with off the shelf harnesses like Claude Code, but also increasingly our own infra) to work at higher levels of abstraction.
- Our view on AI in development is closely aligned with how Simon Willison describes it here.
- You'll thrive on our engineering team if you're excited about this new frontier and eager to learn how best to leverage these new powerful tools.
Self-Starter — You're comfortable building new things in a self-directed way, iterating quickly, and taking ownership (despite being on a remote team)
Product Builder — You're obsessed with the concept of user experience and building high quality product
Hacker — You seek creative solutions to create the most amount of user value with the least amount of programming effort or complexity

Experience working on large-scale, complex apps.
Our frontend is TypeScript/React on web and React Native on mobile — if you're comfortable jumping into the frontend when something needs shipping end-to-end, that's a huge plus!
Although most of your focus will be backend, being able to think about the entire system holistically and improve our architecture is always valuable!

Although certainly not required, we love seeing code or live demos!

Why Readwise?

What we're about: We're on a mission to 10x the practice of reading using software to help our users unlock humanity's collective wisdom.
Our opportunity: Software has revolutionized writing (you would never write a book by hand or on a typewriter) while most reading is still analog.
Our position: We've started solving the problem of retention (remembering more of what you read) and now we're moving into the actual reading experience itself.

We're a fast-growing startup with so many problems to solve and so little time.
We're self-funded (aka bootstrapped), sustainable, and profitable.
Our existing niche product positions us to go after a massive adjacent market.
Although we ship fast, we pride ourselves on building things "right": debugging and adding new features should be a delightful experience for engineers. Engineering has a real voice when it comes to tradeoffs and implementation, ensuring we can ship well over the long term.

We are still a small team of 20 (including 9 engineers) requiring ownership and self-direction.
Everyone ships to production, often multiple times a day :)
We are distributed to the core: max 2 meetings a week with no bureaucracy or time-wasting.
You will own the features and projects you take on — from shaping to shipping.
Did we mention we ship, ship, and ship?

Competitive salary & meaningful equity.
