Senior Software Engineer

Job Post

Part-time Customer Relations Representat (Senior Software Engineer)

Location: Osaka, Japan (Fully Remote)

Compensation: USD 80-120/hour, approx. 5-10 hours/week depending on client load

About Our Company

Our company is a software studio based in Osaka, working with clients across Europe and the Middle East - and now expanding in the US. For 7+ years we’ve shipped web, mobile, and AI products for startups and enterprises.

The Role

We’re looking for an experienced Software Engineer with native-level English who enjoys talking with clients just as much as talking about code.

This is a part-time, fully remote contractor role where you’ll be the bridge between our clients and our engineering team. You’ll join calls, clarify what needs to be built, and keep non-technical stakeholders confidently in the loop. It’s a good fit if you want to stay close to real-world software projects without taking on another full-time engineering job.

What You’ll Do

• Join video calls with clients (discovery, status, follow-up)
• Ask the right questions, gather and clarify technical requirements, and shape user stories
• Translate client needs into clear, actionable tasks for our developers
• Explain technical decisions, trade-offs, and progress in simple, non-technical language
• Prepare short, clear meeting notes and follow-up action items
• Keep clients informed about timelines, risks, and blockers before they become problems
• Spot upsell/cross-sell opportunities and support light sales conversations when it makes sense
• Build long-term, trust-based relationships with key stakeholders

What We’re Looking For

• Native-level English (spoken and written) - you’re confident leading calls with US clients
• 5+ years of experience as a Software Engineer or in a closely related technical role
• Strong understanding of modern software development (web, mobile, APIs, cloud)
• You’re good at “translating” between tech and business and keeping everyone aligned
• Comfortable with US time zones and communication style
• Organized and reliable - you follow up, close loops, and document decisions clearly
• Able to work independently in a fully remote environment

Nice-to-Have

• Previous work with US-based clients
• Experience in customer success, account management, or pre-sales
• Background in FinTech, eCommerce, or AI projects

Time & Schedule

• Part-time: typically 5-10 hours per week (hours may vary by client load)
• Flexible schedule, as long as you can join calls in US time zones when needed
• Fully remote - you can be based anywhere

This is a senior, high-trust role: you’ll be the face of our company for key accounts, and the compensation reflects that. We never ask candidates to pay any fees or purchase equipment as part of the hiring process.

NOTE: you must be a US citizen
