Ask HN: Who is hiring? (February 2026)

Strobe | Software Engineer | Brooklyn, NYC | ONSITE | Full-time | $120k–$250k + equity

We’re building a distributed, software-defined power plant: buildings, batteries, EVs, and on-site generation buying and selling power in real time. Think cloud control plane + embedded hardware + energy markets.

Small, high-performing team. No layers. You’ll own systems end-to-end: design → deploy → on-call.

We’re looking for *fungible generalists*, not narrow specialists. Strong fit if you’re comfortable with: - AWS-heavy backend work (Lambda, APIs, GraphQL, data pipelines) - Operating real-time production systems - Python / TypeScript (Rust a plus)

Depending on fit, you might work on: - Telemetry & control over unreliable networks - Embedded Linux / RTUs (Modbus, BACnet, DNP3) - Market-facing systems and optimization - Operator UIs with real-time streams (React)

Requirements: - Strong production experience - Systems mindset, bias to shipping - Willing to be onsite 5 days/week at Newlab (Brooklyn Navy Yard) - Not remote

Fast pace, direct feedback, real ownership. This is not a 9–5.

Tiger Data (FKA Timescale) [ Global | 100% Remote | Multiple Roles: Eng, GTM, Support + more ] We began in 2017 as TimescaleDB, focused on making PostgreSQL the best database for time-series data. As our customers evolved, so did we.

Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems. What started as a time-series database has become the fastest PostgreSQL for modern workloads. To reflect that evolution, we’re now TigerData—a name that speaks to our speed, precision, and ambition. The tiger has long been part of our culture: fast, focused, powerful. From “Tiger Time” all-hands to welcoming new hires as “tiger cubs,” it’s how we build—decisively, fearlessly, and with purpose.

This is not a reinvention: it’s a reflection of how we already serve our customers today.

Kinelo | kinelo.com | Full-Stack Engineer (AI + Backend) | San Francisco | Onsite

Kinelo manages the new type of hybrid team that will emerge in the future: humans+AI working shoulder-to-“shoulder”.

Our first product helps human software engineering teams deliver more efficiently and more reliably by assisting in coordination and engineering management. But it’s built on a foundational layer that ingests data, knowledge, and process across communications and systems, exposing that to humans and AI alike.

Eventually, Kinelo will become a proper human+AI orchestration layer, managing entire companies, and our goal is to have Kinelo run Kinelo (we already dogfood it today).

We’re looking for high ownership individuals to join our small team and shape its direction. We also just opened a new SF office and new hires will have the ability to help shape company culture, engineering practices, architecture, and roadmap.

- ~8 years professional experience, including the pre-LLM days with strong CS fundamentals

- A balance of wisdom from experience and optimism about the future

- Strong TypeScript and Postgres (or other RDBMS) experience at scale and with high reliability (SaaS apps, APIs, etc)

- Experience with a variety of technologies, including containerization, distributed systems, and at least one strongly typed programming language (Go, C++, Java, etc)
