I'm the Director of Technology at Crossref and I'm looking for a Head of Infrastructure Services to join my team. This role will lead the strategy and evolution of Crossref's infrastructure ecosystem, own the infrastructure roadmap, and lead and develop our Infrastructure Services Team.
Crossref is a not-for-profit organisation that runs infrastructure that connects thousands of scholarly publishers and millions of research outputs, serving an increasingly diverse set of communities across scholarly publishing, research, funding, and beyond. Our system is a complex mix of legacy and modern components, some parts over 20 years old and tightly coupled, running on AWS with Terraform, Java, Clojure, Elasticsearch, and PostgreSQL. You'll play a key role in our efforts to modernise this system into a set of more loosely connected services.
We're looking for someone who's as comfortable getting into the weeds of cloud infrastructure as they are leading a team. If you've grown from a strong technical background into leadership, and enjoy using your technical expertise to help a team do its best work, this could be a great fit for you.
This role is fully remote, we are hiring globally, but we will need at least 2 hours overlap with European timezones.
Full job description and application form here: https://www.crossref.org/jobs/2026-09-01-head-of-infrastruct... We don't use AI as part of the recruitment process, all applications are screened by me. For any questions, feel free to message me here: https://www.linkedin.com/in/dtkaczyk/

Loft builds and operates shareable satellites so customers can fly a payload without building a spacecraft. We integrate, launch, and operate the mission end to end: Earth observation, IoT, on-orbit AI, national security. 30+ missions flown since 2017, fleet on track for 30 satellites by 2027, offices in SF, Golden, and Toulouse.
Our Cloud Infrastructure team runs the ground segment that talks to the fleet. This is an SRE role with a twist: we apply DevOps practices to spacecraft control (we call it SatDevOps), and we'll train you to operate the satellites.

Looking for: strong public cloud (ideally GCP), deep Kubernetes, one backend language (Go/Python/Rust/C++/Java), IaC + CI/CD in anger, and someone who can design HA systems and then run them. Nice to have: FinOps, security tooling, orchestration in resource-constrained environments.
Benefits: 100% company-paid medical/dental/vision for you and dependents, 401(k) + equity, flexible PTO + 12 holidays, 14/10 weeks paid parental leave, daily catered lunch, relocation assistance, and time with the team in France.

Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.
We are currently looking for the following roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.
Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, and for you to be located within Delhi/NCR, Pay is competitive (9-12 LPA), and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns. We are not flexible on in-office work because of operational requirements - please do not apply if you can't relocate/work from office.
Hiring across OS, software, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.
Systems Engineer - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.
Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.
Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.
Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.
To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P (reiterating this, because we receive so much AI spam now. Thanks for your time!
