Senior Implementations Consultant - Professional Services

Flatfile is full of builders driven by a dual desire to make cool stuff and create tangible value. We pride ourselves in obsessing over the details but also grounding our decision-making and pace in whether we’re doing what’s in the best interest of our end users.

This is a highly technical and strategic role operating at the core of customer enablement and product execution. You’ll act as the primary technical lead for enterprise clients, driving complex implementation efforts and architecting robust Flatfile integrations within their ecosystems. As a subject matter expert, you will manage API-driven workflows, troubleshoot integration challenges, and guide clients through deployment best practices that accelerate their time-to-value. Success in this role demands deep technical fluency, systems-level thinking, and the ability to translate evolving customer requirements into scalable, production-ready solutions.

This role reports to: Technical Chief of Staff

Why are we hiring for this now?

Flatfile is a post-product market fit AI company with rapidly accelerating growth, tons of runway, a lean, hungry, and sharp team playing for a huge outcome. We’re closing massive enterprise deals and evolving our platform quickly to scale with the growing demand. As we bring on more complex and high-value customers, the need for experienced, hands-on technical implementation specialists to ensure their smooth onboarding and successful adoption is critical. We have an ambitious roadmap ahead of us and need someone excited to lead the charge on many of these customer-impacting projects.

We want you to be a part of this.

In this role, you will:

• Partner with Program Management to lead the end-to-end implementation process for Flatfile's enterprise customers, from initial discovery to successful go-live.

• Act as a trusted technical advisor, guiding customers through best practices for data onboarding, integration, and workflow design.

• Conduct in-depth discovery sessions to understand customer business processes, data structures, and integration requirements.

• Translate complex business needs into clear, actionable technical specifications and implementation plans.

• Develop and implement custom solutions using Flatfile's APIs, SDKs, and configuration options to meet unique customer use cases.

• Write clean, efficient, and well-documented code (e.g., JavaScript/TypeScript, Python, etc.) to customize and extend Flatfile's capabilities for specific customer needs.

• Create technical documentation (e.g., diagrams, solution workflows, integration specs) to guide implementation team

• Collaborate closely with product, engineering, and sales teams to communicate customer feedback, identify product gaps, and contribute to the evolution of our platform.

• Provide technical training and support to customer teams, empowering them to effectively utilize Flatfile.

• Proactively coordinate with program management to identify and mitigate risks during the implementation process, ensuring timely and successful project completion.

• Contribute to the continuous improvement of our implementation methodologies and tools, sharing best practices across the team.

Consider applying if you have:

• 5+ years experience in a customer-facing technical role (e.g., Solutions Engineer, Implementation Consultant, Technical Consultant) with a strong track record of successful enterprise software implementations.

• Demonstrated hands-on experience and proficiency with programming languages such as JavaScript/TypeScript, Python, or similar, for scripting, automation, and API integrations.

• Expertise in data manipulation, transformation, and API consumption (REST, GraphQL).

• Proven ability to conduct effective discovery sessions, gather business requirements, and translate them into technical solutions.

• Strong problem-solving skills with a meticulous attention to detail and a passion for finding elegant solutions to complex challenges.

• Excellent communication, presentation, and interpersonal skills, with the ability to articulate technical concepts to both technical and non-technical audiences.

• Experience working with diverse stakeholders including IT, business users, and executive leadership.

• A proven track record of managing multiple projects simultaneously and prioritizing effectively in a fast-paced environment.

• Operate at an unreasonable pace.

• Capacity to do large amounts of meaningful work quickly with little direction or oversight.

While many consulting roles are similar, Flatfile’s roles are unique. With that in mind, you should pass on applying if:

• You prefer a purely advisory role and lack interest in hands-on coding and technical problem-solving.

• You are uncomfortable navigating complex organizational structures and influencing diverse stakeholders to drive project success.

• You shy away from deep technical discussions with engineering teams or explaining technical solutions to non-technical business users.

• You do not want to be hands on keyboard developing solutions for our customers.

• You prefer a highly structured environment with minimal ambiguity, as this role requires adaptability and independent problem-solving in a rapidly evolving product landscape.

• You’ve never worked in a fast-paced environment. We move quickly, and if you get frustrated when priorities change rapidly, we’re not the place for you.
