Job description

Equity-Based Compensation

Pre-salary period: Until you begin receiving your base salary in cash, you will be compensated in stock options. You will be granted stock options with a notional value equal to 2× your expected base salary, pro‑rated for the period before your salary starts, subject to board approval and the terms of the Company’s equity incentive plan.

After the seed round: Once the Company closes its seed financing round, you will start receiving your agreed base salary in cash. Any additional agreed compensation above the base salary will be delivered in the form of stock options that vest over time in accordance with the Company’s standard vesting schedule.

Liquidity on vested equity: In connection with the seed round and any subsequent qualified financing rounds, and subject to applicable law, Company policy, and investor/board approval, you may be given the opportunity to sell a portion of your vested shares (secondary liquidity).

Please DON'T APPLY if your main goal is to find a work to cover your basic needs; we need financially independent teammates that have their basic needs covered. We are open for full / part time cooperation.

The Mission

We are building Spala — a local‑first visual backend builder that bridges the gap between No‑Code simplicity and Full‑Code flexibility. We aren't just building a CRUD app; we are building a visual IDE, a Compiler, and a Runtime Engine all in one.

We are looking for a Dev to help us speed up development.

You won't just be writing endpoints; you will be building the engine that generates and executes endpoints.

The Tech Stack & Challenges

You will inherit and expand a sophisticated monorepo architecture (vite + express). Key technical components you will own:

• monorepo architecture (vite + express)

Key Responsibilities Ideal Profile Why Join?

To Apply:

Please tell a bit about yourself and what you are looking for.

NOTE:

If you are bored with regular projects or outsource projects, you want to bring light back to your life by joining the team of real engineers, and have fun and joy from your work - you are a right fit.
