TechTalk | Principal Software Engineer, Agentic Engineering | Vienna, Austria | ONSITE/HYBRID | Full-time | EUR 80,000+ gross/year

For those who know what they're doing - even without AI. Our focus is agentic engineering: building and improving systems, workflows, and engineering practices around AI agents and AI-assisted development. We use AI tools heavily, but we expect engineers to know when they help, when they hurt, and how to keep generated code out of the debt spiral.

This is a hands-on role for someone who cares about maintainability, testing, refactoring, deployment safety, and engineering judgment under pressure. You should be able to improve systems yourself, help other engineers work effectively with AI, and raise the bar across teams.

You’ll likely fit if DORA metrics are useful to you, not decorative; if you know why small commits matter; if you’ve seen what a good deployment pipeline does to a team; and if you can use AI to scale quality, not just output.

Apply at jobs@techtalk.at. No cover letter. Instead, tell us about a system you improved with AI, and what your contribution actually was. Find out more: https://techtalk.at/job-offers/principal-software-engineer-a...

We have the following open positions:

* Lead Software Engineer – we're looking for a strong technical leader to drive one of our product squads. You'll shape architecture, mentor engineers, and ship meaningful product improvements.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security. We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome. We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team. Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git. We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
