About you

If you are passionate about open source and want to help us make a significant impact in the marketing automation space, we encourage you to apply!

Please note that we welcome interest from candidates with varying levels of experience; many successful candidates do not meet every single requirement. Additionally, studies have shown that people from underrepresented groups are less likely to apply to a job unless they meet every single qualification. If you're excited about this role, please apply and allow our team to assess your application.

With that being said, here are some things that we’re particularly looking for, which we believe would enable you to excel in this role:

• Totally fluent in written and spoken English with a keen eye for detail, good grasp of professional etiquette when it comes to development, and a personal history of open source contribution and collaboration so we can get a sense for how you work with others in the capacity of a senior developer

• In a timezone which overlaps with UTC +/- 5 hours (where most of the core team live)

• Super organised and proficient in using tools which enable you to keep track of your commitments in multiple projects at once

You probably enjoy solving complex technical challenges while maintaining a focus on user needs. You're someone who gets satisfaction from improving code quality, hunting down elusive bugs, and mentoring others in their development journey. You have a natural inclination toward documentation and clear communication, understanding their importance in open source projects. 

Community-minded and approachable, you find energy in working with contributors of all experience levels and take pride in helping them succeed. You're comfortable balancing independent work with community engagement, and you're motivated by seeing your contributions make a tangible impact on a widely-used platform. 

Above all, you're someone who values sustainable development practices and believes in the mission of making powerful marketing tools accessible through open source software.

As this role will involve taking on elevated privileges within the Mautic project, if you're not already part of the Mautic Core or Security Team, you will need to be willing to undergo background checks prior to being appointed. Successfully passing these is a requirement for being offered the role.

Getting paid

You will be a contractor responsible for raising an invoice each month via our Open Collective for payment.

Payment will be based on the days worked that month at an agreed daily rate. As a contractor, you will not be paid for sick leave or vacation time.

All staff are encouraged to take the time needed to rest and recharge, ensuring that your productivity and creativity remain high. However, please note the following guidelines to ensure this policy benefits both you and the team:

• To maintain team productivity and project continuity, you must coordinate with your manager and team members when planning time off. Advance notice and consideration of project deadlines and team schedules are essential.

• It’s your responsibility to ensure that your commitments are managed effectively before taking leave. This may include delegating tasks or completing critical work ahead of time.
