Job Description

We are looking for two mid-level software engineers to join our small, tight-knit team and help us build our next project. However, we are looking for experience in a few different areas of specialization.
When applying, please indicate which specialties you’re interested in. You are welcome to express interest in more than one!

Specialties:

• DevOps/Infrastructure
• Audio
• Creature/NPC AI

Please also note that Mobius does not allow the usage of Large Language Models and similar generative AI tools (e.g. ChatGPT, Claude, Copilot) as part of our work.

Core Qualifications

Regardless of specialty, all engineers at Mobius work closely with the rest of the team and are expected to contribute to the realization of a shared creative vision. We iterate quickly, playtesting as often as every two weeks, and engineers are an important part of that loop. You should be comfortable working with team members to clarify ambiguous requirements, care about the quality and maintainability of your code, and be willing to revisit and redesign the systems you make in response to changing design and playtester feedback.

Core Required Skills

Skills we expect a new hire to have already

• Solid foundation in software engineering (data structures, algorithms, OS concepts)
• Comfort with mathematics concepts relevant to 3D game development (algebra, 3d vectors, transformation matrices)
• Comfort giving and receiving technical feedback (e.g. code review)
• Experience with technical collaboration via source control
• Ability to independently design and plan small- and medium-scope systems (such as an individual interaction or game mechanic), and collaborate on the design of larger systems (such as the game’s save system)
• Soliciting input from appropriate stakeholders when making project decisions
• Comfort collaborating across disciplines (design, art, audio, etc.)
• Shows care for the context of tasks and the larger goal, versus just checking off requirements

Core Recommended Skills

Skills we expect a new hire to have already or learn within the first 6 months

• Proficiency with C# and the Unity game engine
• Proficiency implementing gameplay features and core systems of a video game
• Proficiency with Git
• Familiarity with game development pipelines and workflows

• Comfort reading technical papers to implement cutting edge techniques

Core Bonus Skills

Skills we don’t require, but are worth mentioning in your cover letter and at your interview!

• Prior work experience at a small/indie game studio
• Shipped at least one game
• Proficiency with C++ and low-level memory management
• Familiarity with game physics concepts (e.g. momentum, friction, torque, integration)
• Experience with platform certification and submission pipelines
• Experience writing networking code
• Experience working on a live game or service

Specialty: DevOps/Infrastructure

We are looking for an engineer to help maintain our technical infrastructure, from the physical hardware maintenance of workstations and on-premises servers to the implementation of build pipelines. An ideal candidate would have a broad knowledge of computing concepts and a passion for identifying bottlenecks in team productivity that can be solved with better tools or technology.

Required Skills

• Security-conscious mindset

Specialty: Audio

We are looking for an engineer with a good ear for audio who can work hand in hand with our audio designer(s) and creative director to integrate the sounds and music of the game to a high level of quality. An ideal candidate would have a background in audio engineering as well as software development, and be passionate about creating a sonic experience that is immersive and true to the world we’re building.

Required Skills

• An ear for identifying audio issues (e.g. missing sounds, popping, stuttering/crackling, incorrect volume, incorrect spatialization)
• Experience integrating audio middleware into a game engine (e.g. Wwise, FMOD)
• Experience collaborating directly with audio designers and/or composers
• Familiarity with real-time audio systems and their constraints
