Employment Information

The software development team is the central nervous system of Liberal Logic Inc. While our main business area is the core software for professional video and audio equipment, we also use the knowledge we gain there to work on development in completely different areas. Success in areas where software development is essential depends on the behavior of the software you and your team create. The things we consider important are wide-ranging. The following is a list of these things, but we do not expect you to cover all of them. The reason we have listed so many items here is to minimize the mismatch between expectations and reality in both corporate and individual recruitment, by having you look at the list and understand the direction we are aiming for. Liberal Logic Inc. is openly accepting applications. If you are interested in joining us, please reach out through our Contact page. The hiring process includes a simple technical test. This technical test is either a technical test that simulates a small-scale software development project that can be completed in a few hours, or a technical test that simulates a small-scale software development project that can be worked on at any time during a one-month period. The salary will be decided after consultation and agreement between both parties, taking into account a variety of factors, including your previous career and the content of your specific development achievements, the results of the technical test conducted during the recruitment process, your approach to engineering and other matters, your philosophy on work, and social and economic conditions.

What We Value

Integrity and Passion

Alignment with our philosophy, passion for craftsmanship, and the sincerity, humility, and dedication to pursue excellence without compromise

Teamwork

Positive communication, taking ownership, and the openness to listen, learn, and grow together

Commitment to Engineering

The ability to design, implement, and debug with your own hands, and to communicate your work through clear documentation

We work every day with the desire to create new stories with our customers by delivering products that exceed their imagination. We value the attitude of being honest, humble, yet uncompromising — always asking ourselves, “Can we create something of even greater value for our customers?” No one can accomplish everything alone. That is why we contribute to the team with positive words, listen to feedback, and build relationships where we can elevate one another.

Gather requirements, design, implement, verify, and see it through until the customers we deliver to succeed in their business. It is not enough to simply build something that works — you must be able to explain why you designed it that way, communicate it through documentation, and convey its value to the market. We believe that this integrity toward technology and unwavering dedication to customer success are what sustain the value of our products.

The attitude of each individual shapes the future of our company. If you want to take on the challenge of developing complex systems — whether that involves computers, microcontrollers, software, firmware, communication systems, computational systems, or systems engineering — or if you feel that your current environment does not allow you to build what you truly envision, please get in touch. Those who only criticize the achievements of others without offering alternatives, or those who take pleasure in belittling others, are not welcome here, no matter how talented they may be.

We look forward to working with those who share these values.

Who We're Looking For

Integrity Toward Your Work and Customers

Someone who takes responsibility for their work and the success of customers, faces inconvenient truths head-on, and builds trust through actions

Self-Learning Ability and Drive to Grow

Someone who ventures into unfamiliar technical domains on their own initiative and continuously learns to surpass who they were yesterday

Proven Ability

Someone with solid technical skills who can design, implement, and deliver working systems — demonstrated through results, not resumes or titles

What we look for in the people we work with is not their resume or title. It is the honesty to be straightforward with customers and teammates even when the truth is inconvenient, the drive to learn and move forward on your own even in unfamiliar territory, and the ability to build something solid with your own hands. Each person’s strength in these areas directly impacts the success of our customers and teammates.
