The Role

We're hiring a Fractional Project Manager (Senior Software Engineer) to support our internal leadership and serve as a technical project lead in client-facing engagements.

This is a part-time, fully remote contractor role where you’ll guide software projects from discovery through delivery-working closely with clients, designers, and engineering teams to ensure projects stay technically sound, well-scoped, and aligned with business goals.

You’ll act as a technical bridge between clients and our engineering team, helping clarify requirements, shape implementation approaches, and ensure delivery runs smoothly. This role is ideal for a senior full-stack engineer who enjoys technical leadership, project ownership, and client communication without moving into a full-time management role.

​

What You’ll Do

Lead technical project planning

• Participate in discovery sessions with clients to understand product goals and technical requirements
• Help translate business objectives into clear technical scope and implementation plans
• Identify risks, dependencies, and technical constraints early

​

Drive engineering execution

• Work closely with engineers and designers to guide development and ensure technical quality
• Help break down features into clear tasks, tickets, and milestones
• Ensure projects stay on schedule and blockers are addressed quickly

​

Support architecture and technical decisions

• Contribute to system design discussions and recommend practical implementation approaches
• Evaluate trade-offs around tech stack, integrations, scalability, and maintainability
• Help ensure engineering best practices are followed across projects

​

Facilitate communication with clients

• Join client meetings to explain technical progress, timelines, and challenges
• Translate complex technical concepts into clear updates for non-technical stakeholders
• Keep stakeholders aligned on scope, priorities, and delivery expectations

​

Maintain delivery visibility

• Track project progress, risks, and blockers across engineering teams
• Ensure clear documentation of decisions, milestones, and technical direction
• Support sprint planning, reviews, and project updates when needed

​

Improve delivery operations

• Introduce lightweight processes to help teams work more effectively
• Help improve coordination across design, engineering, and client stakeholders
• Support internal teams in maintaining consistent project execution standards

​

What We’re Looking For

• Native-level English (spoken and written); comfortable leading calls with US clients
• 7+ years of experience as a software engineer, ideally with full-stack development experience
• Experience working on web platforms, APIs, cloud infrastructure, or modern SaaS systems
• Prior experience in technical leadership, tech lead, or project ownership roles
• Strong understanding of software development workflows and agile delivery
• Ability to translate business requirements into technical tasks and engineering plans
• Excellent communication skills and ability to work with both engineers and non-technical stakeholders
• Highly organized and proactive-you help keep projects moving forward

​

Nice-to-Have

• Experience working with US-based clients or distributed engineering teams
• Background in technical consulting or agency environments
• Experience with modern full-stack ecosystems (Node.js, Python, React, cloud platforms, etc.)
• Exposure to AI-enabled products, data platforms, or complex integrations
• Familiarity with DevOps practices, CI/CD, and scalable cloud infrastructure

​

Time & Schedule

• Part-time: typically 5-10 hours/week (may vary by client load)
• Flexible schedule with availability for US time zone meetings when needed
• Fully remote-based anywhere

This is a senior, client-facing technical role where you’ll help guide engineering delivery and maintain strong relationships with clients. Compensation reflects the technical leadership and experience required.
