Senior Software Engineer (Onsite - SF)

https:/beam.biz/sitemap.xml • San Francisco, CA, United States • $200k - $250k / year • 2w ago

We are looking for software engineers, preferably proficient in TypeScript. We prefer people who are comfortable in a full-stack role and have superhero strengths in building scalable backends. We play with a lot of hardware and spend a lot of time thinking about developer UX. We like written communications. We prefer to keep things simple and don't overthink first implementations. You should generally be curious, comfortable with the unknown, love experimentation, and be able to move fast.

Backend API

Our high-level goal is to build a device/manufacturer agnostic integration layer that connects to various devices and exposes their functionality through a simple API. This task involves integrating dozens of different IoT brands and their protocols (Z-Wave, Zigbee, BACnet, OEM API...etc) and neatly organizing them amongst common functionality. We spend a lot of time building this part of our stack.

Client Libraries & APIs

Our customers tend to be quite technical and some of them even contribute code to our SDKs. In general, we spend a lot of time creating tools and client libraries to make interfacing their applications with devices easier. We strive to standardize device functions across brands and hide all the nasty complexity away. For example, below is an example from our TypeScript library:

import Seam from "seamapi"; // Seam will automatically use the SEAM_API_KEY environment variable if you // don't provide an apiKey to `new Seam()` const seam = new Seam(); const { devices: [someLock] } = await seam.locks.list(); // If the lock is opened, lock it, else unlock it. Code works irrespective of the brand. if (someLock.properties.locked) { await seam.locks.unlockDoor(someLock.device_id); } else { await seam.locks.lockDoor(someLock.device_id); }

You can read more about how we strive to standardize device functions across brands here. Alternatively, you can also play with our client libraries below:

Javascript/TypeScript → npm install seamapi
Python → pip install seamapi
Ruby → gem install seamapi

Qualifications:

4+ years of full-stack development experience with expertise in TypeScript.
Strong in SQL, particularly with PostgreSQL, including schema design, query optimization, and performance tuning.
Familiarity with SRE principles, including incident management, monitoring, and system reliability.
Experience in designing and maintaining scalable backend APIs and client libraries, with a focus on performance, reliability, and developer experience.
You maintain a healthy balance between perfectionism and actually getting stuff done.

Preferred Qualifications

Prior experience working with both high growth stage private startups and larger scale companies.
Previous experience or interest in IoT, hardware integration, or related fields is a bonus.
