Remote Backend + Front End + Linux + Python Jobs

Please, pleasy-please, read and respect the following 5 notes before applying with a single click:

1. Instead of using the RemoteOK built-in application system where the systems sends the employer a note like "John is interested in this position, click here to see his RemoteOK CV" please just send your CV in PDF format to the following E-Mail address: [email protected]
2. We'll pay you 1500 EUR per month for 6h per day, Monday to Friday. It's hard to stay focused for 8 hours straight, therefore more than 6h per day don't make sense. You can have other jobs on the side, but not while you're dedicating your daily 6h to Lightup. The 6h must get spent dedicated, continous, without interruption and without doing other tasks at the same time.
3. You'll find a keyword at the end of this job description. Include it in your E-Mail to us, either in the subject or in the body of your E-Mail, so that we know you're clear about what you're actually applying for vs. just applying for a ton of jobs in a random fashion because that's not cool. E-Mails without the keyword will get ignored.
4. If there are should be typing or grammar mistakes in your CV we'll already know that you don't pay much attention to detail and in this case you're the wrong candidate for this job.
5. Thanks for your cooperation, these are some prerequisites to save time on both sides. :-)
   

Now, about the actual job: Lightup was established in 1998 in Frankfurt, Germany as a Hosting & Domain Provider and today is still a small but international Internet Full-Service & Telephony Service Provider, focusing heavily on web-based telecommunication services (VoIP) since 2011. We're need more developers to create more cool web telecom-related projects and apps. 100% of our team works from remote.

To compensate for the monthly kind of low payment of just 1500 EUR, which may be too low for some parts of the world, we're offering you a quite unique profit sharing model: For every web project that you turn into reality, you'll receive 20% of the profit that this project generates for as long as you stay with Lightup. That way, you'll be also extra motivated to extend the service you just created and keep it running and improve it over time while it's growing, generating you even more profit every month. We love to see our employees happy, and if the company is profiting as a whole, you as an individual should profit from that, too.

We'll create the ideas, and you'll put these projects into reality. Your profile:

• You are awesome at working independently and self-sufficient, you are great at researching using Google and AI tools extensively to find the infos you need & to learn.
• You could, in theory, build functional websites from scratch without relying on AI or programming tools.
• You can write code from scratch using your brain, without AI, and just by using a text editor (if need be).
• Coding means actually writing manual code for you, not copy'ing & paste'ing code snippets that you found on the web. To you, coding also doesn't mean dragging objects from A to B in some visual "programming" tool.
  

In other words, you're a real programmer!

Your skills:

• Perfect English & typing proficiency. No typos, no grammar mistakes.
• You can create Android apps from scratch, from start to finish, by yourself.
• You can handle the Linux shell and you can navigate through a Linux-based filesystem using just command line tools.
• You're a master of the programming language(s) of your choice that allow you to create web-projects (PHP, Python, whatever).
• You are very good at SQL, you understand the inner workings of e.g. MySQL and thus you know what makes queries slow and what makes them fast.
  
• All of this requires that you already have plenty of experience, if you are new to all of this or if you think AI will be able to handle these requirements for you, then you are not the right candidate.
• You have used vi or vim before.

What the job will look like in practice:

• We're defining the inner workings and features of the to-be-created web-based service, or app, together.
• You'll start at 0 and build these services & apps from the ground up, independently, by yourself.
• We'll communicate permanently via Slack.
• Here you can find the keyword so that we'll know you actually read until here: Work-in-underpants.
• No travelling required, you can do this job from anywhere in the world with a stable, broadband internet connection. External keyboard + external mouse required in case you're working on a laptop, otherwise you would be too slow for what we expect from you.
• We are a German company, and precision and speed are key to this role. :-)

And now, we're looking forward to read from you - thank you!

💰 Profit sharing

Hi!

Lightup Network Solutions GmbH & Co. KG is a small ISP and telecommunications service provider (VoIP) based in Frankfurt, Germany. Lightup's team is 100% remote, distributed worldwide (Germany, Portugal, Serbia, Morocco, Brazil, Colombia) and consists currently of just 7 mostly non-tech people. Now we need a hybrid Web Dev / Sys Admin tech pro to join our small team. Lightup was established in 1998 as a ISP focused on webhosting and dedicated servers. Since 2011 Lightup has shifted its core business towards internet-based telecommunication services, primarily so-called DIDs a.k.a. virtual telephone numbers along with international retail and wholesale call termination (VoIP, SIP). In 2022 Lightup became a licensed telecom operator in Switzerland and the wholesale business has been booming since then.

Your tasks would be:

• Short-term (now - 6 months): Create multiple new commercial telecom-oriented web-based services from scratch based on the team's ideas (PHP + MySQL preferred, but really up to you)
• In the mid-term (6 - 12 months), create, re-design & code from scratch successor sites for outdated Joomla-based sites
  
• Create Linux console-based or web-based scripts and tools to support the team, such as customer accounting scripts / accounting & billing automation or VoIP buy- and sell-rates output automation (Bash, Perl, Python, PHP - your choice)
• Take care of 30+ KVM-based VMs and the 20+ underlaying physical servers running CentOS
• Keep CentOS installations updated, migrate those which are too old to new installations
• Set up new VoIP customers in our VoIP system / cluster (Asterisk, Kamailio)
• Analyze, troubleshoot and fix SIP and DID call issues / Work & communicate with vendors and customers alike
• Provide technical customer & order support for our 2 Joomla-based retail telecom services
  
• Create a new API from scratch for lawful interception compatibility / requests
  
• Constantly communicate with the team (WhatsApp, Slack) and help them to make their non-tech jobs easier by the creation of cool & useful new tools
  

Some commands / tools that should be familiar:

• vim and vi
• ssh, rsync
• sort, cut, tail, head
• awk, sed, tr, wc
• grep, uniq, paste, join, shuf
• top (and understand what you're seeing)
• ps (and understand what you're seeing)
• ifconfig, netstat, tcpdump, ping, traceroute, mtr, whois
  
• ls, cd, cp, mv, rm, cat, echo, mkdir, find, date, df
• screen, less, more
• yum
  
• (Bonus: sngrep, kamctl, sipsak)

If you're not typing most of these commands multiple times on a daily basis into your SSH client or into your local console then you can stop reading at this point and skip to the next job offer. Else, since you are a Linux console person, please read on...

Some server daemons, binaries and tech that you'll be dealing with:

• Apache / httpd
  
• MySQL / MariaDB / mysqld / mysql
  
• sshd
• KVM / qemu / vncserver
• cron
• iptables
• Bash
• ProFTPD
• Asterisk
• pssh
• Kamailio
  
• X / GNOME
• tinydns / dnscache
• Nagios
  
• Sendmail, postfix, exim, SpamAssassin, Dovecot (via DirectAdmin)
  
• MRTG
• IPMI / KVM-over-IP
• BackupPC
  
• (Optional network admin bonus: Juniper M- and SRX-series routers, HP ProCurve switches, vrrp, BGP, RIPE)

Minimum languages that you'll need, software and protocols that you'll have to either already know or learn:

• Bash Shellscript
• PHP
• Joomla (from scratch, heavily modified, forget click-to-install modules/add-ons)
• MySQL / MariaDB
• Apache Webserver
  
• SIP
  
• Asterisk

This is a freelancer position, meaning you'll be responsible for taking care of paying taxes, health insurance, social insurance, pension fund etc. by yourself.

You'll be working just 6 hours per day, not 8 hours. But since Lightup's team is global and so are our customers those 6 hours will be spread over the course of a day European time (CET, Berlin) between 10:00 and 22:00. Imagine it like 12 hours standby per day (WhatsApp, Slack, E-Mail) but effectively 6 hours will be dedicated to Web Development, Sys Admin and Tech Support tasks.

Your profile:

• Highly self-motivated & independent, but still a team player
• Good communicator, friendly attitude
  
• Flexible, curious to learn & try new
• Very accurate, with tendency to perfectionism
• You're working careful and exact, and you re-read your changes multiple times before you actually save the file
• Multiple years Linux experience & created multiple web-based services (PHP + MySQL or comparable) from scratch
• You are a real coder, you don't drag & drop buttons and menus and call that coding
• You can edit / read / write code with a text editor on your Linux console and you actually understand what you're reading and writing
  

Education, age, gender not important. Yes, we're looking for a Linux / Web Dev geek / pro. If you're living in your mothers basement for the last 10 years that's OK. If you're never leaving your appartment that's OK too. If you're happily married and have 4 children that's fine too. Coding on laptop is inefficient and slow, so if you are a nomad you need at least a real keyboard + mouse or you'll be too slow.

Thank you for reading until this point and looking forward to read from you via E-Mail! :-) -> [email protected]
