whoishiring.jobs – find you dream tech startup job

I'm Wilson, co-founder of Post Up. We're building the Databricks for content production. Our orchestration engine coordinates pipelines end to end and turns post-production workflows into a persistent graph of assets and transformations, which are deterministic, verifiable, and nearly instant at scale, powered by a high-performance compute layer.

We're building this AI-native from the ground up; ML inference is embedded throughout the pipeline, not bolted on.

Stack: On-prem, HPC clusters, distributed storage systems, GPU pipelines, real-time video compute.

We're looking for our founding senior backend engineer who wants to work on genuinely challenging infrastructure problems across distributed systems and media processing with immense scale. Should be familiar with Golang, Postgres, Distributed systems, Distributed filesystems (e.g. HDFS, Ceph, etc).

Brandfetch (https://brandfetch.com) | Senior Backend Engineer | Remote | Full-time

Brandfetch is the internet’s canonical source for logos and brand assets. Think GitHub for brand identity: a brand repo that auto-indexes public assets, lets brand owners “commit” changes once, then propagates them—instantly and immutably—through CDNs, plugins, and APIs used by companies like Google, Canva, Salesforce, and soon … everywhere.

Problems you'd work on:

- Nightly curation bot auto-fixing outdated assets across 52M+ repos

- Next-gen ingestion and partition-key schema to leap from millions to billions of assets

- MCP server that exposes structured brand data to any AI agent or LLM, letting them fetch brand context on demand

- Vector search: surface any logo with ≥90% similarity in <50ms

- Real-time metering that pings Stripe the instant a user tops their quota

Stack: Node.js, TypeScript, Python, AWS (Lambda, DynamoDB, CloudFront, S3, CloudFormation), Serverless.

You:

- 8+ years of experience in backend software development.

- Proficiency with AWS tools (Cloudformation, API Gateway, DynamoDB, Lambda, Cloudfront, S3, IAM, OpenSearch).

- Experience with building REST APIs.

- Ability to write well-documented, clean code.

- Experience with building DevOps pipelines using Serverless.

- Great communication skills (we work across multiple timezones and document everything).

- Experience with Machine Learning.

Competitive salary + equity in a profitable, growing company.

*Labor Solutions (YC-style) | Senior Software Engineer | Remote (India) | Full-time*

We run a worker wellbeing and compliance platform used by global buyers and their supply chain sites across Asia. We're in the middle of a meaningful migration and platform buildout — you'd be joining at a point where architectural decisions matter and your fingerprints will be on the system for years.

*The work:* Our stack is Django + Python on the backend, dbt for data transformation, React/Next.js on web, and Expo/React Native for mobile. We run on AWS and Azure. Right now we're migrating legacy services while simultaneously shipping new features — so you'll need to be comfortable holding both in your head.

*What we're looking for:*

- Strong Python/Django chops — you've built and maintained production APIs, not just tutorials - Comfortable with React/Next.js; bonus if you've touched Expo or React Native - You understand what a data pipeline actually does (dbt experience a plus, but SQL fluency matters more) - Cloud experience on AWS or Azure — not ops, but enough to not be blocked - You care about code quality without being precious about it

*What this isn't:* This isn't a greenfield startup with infinite runway. It's a real product with real users, real technical debt, and a migration in progress. If that sounds like a problem, this role isn't for you. If that sounds like the most interesting kind of work, let's talk.

*Details:* - Fully remote, India-based - Senior Software Engineer title

Stream | Amsterdam (NL), Skopje (North Macedonia)| Remote possible | Full Time | Visa Sponsorship

We power real-time Chat, Video, Activity Feeds, and AI Moderation for apps like Strava, Bumble, eBay, and Patreon - billions of API requests per month, millions of concurrent users.

We're looking for a hands-on Lead Engineer (Staff / Principal level) to own Platform & Infrastructure.

Reports directly to the CTO.

Small, senior team - you'll write code most of the time, not run a process org. First 6 months focus on three things with measurable outcomes:

* Cloud cost optimization (AWS/GCP) — tooling and guardrails, not reports

* Platform reliability and scalability — SLOs, observability, hardening

* Architecture decisions on Kubernetes, databases, and cloud provider strategy

Stack: Go, Python, AWS, GCP, Kubernetes, PostgreSQL, CockroachDB, Redis, Terraform.

Looking for: software engineering background (Go or Python, not scripting-only), production cloud cost optimization experience, real distributed systems depth, and active AI tooling use in your engineering workflow.

Not a fit if: you're security/compliance-heavy, scripting-only, or dependent on large-org support structures.

Aerofex | Senior Flight Software Integration Engineer (Ardupilot / Simulink) | Remote / Los Angeles | Contract

Aerofex is a rapidly-growing aerospace startup developing next-generation thrust vectoring and VTOL propulsion technology for manned and unmanned platforms. We are seeking an experienced engineer to support the migration of an existing flight-control implementation from a flight-verified Simulink-like development environment into an ArduPilot-based production implementation.

This is a 1-2 month contract position, with potential for future full-time work. The primary task is to create a custom ArduPilot airframe configuration for a (slightly) nonstandard vehicle. This work will focus on actuator/output mixing, PWM output expansion, firmware integration, and hardware-level debugging on a Pixhawk-based flight controller. A successful candidate will have worked closely on a similar task and is very familiar with Ardupilot.
