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- In the mid-term (6 - 12 months), create, re-design & code from scratch successor sites for outdated Joomla-based sites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.
