Full Job Description

Sologic provides software and instructor-led training to help organizations solve and prevent problems in a structured and collaborative way. Through techniques like Root Cause Analysis and Failure Modes & Effects Analysis, we empower continuous improvement programs that enhance safety, improve equipment performance, and deliver high-quality products.

We're looking for a strong C# developer who is just as comfortable in a customer scoping call as they are in an IDE. This is a hands-on technical role with real customer ownership - you'll be the primary point of contact for integration projects from first conversation through go-live and beyond.

You'll work closely with customers to understand their systems, scope realistic solutions, build and share working prototypes, and support deployments in their environments. Clear communication and genuine curiosity about customer problems matter as much as your coding ability.

We have a strong preference for someone located in the Seattle or Washington DC areas.

WHAT YOU'LL DO

Serve as the primary technical point of contact for customer integration projects, from kickoff through delivery
Lead scoping discussions to understand customer systems, surface constraints, and define realistic integration approaches
Build prototypes, proof-of-concept implementations, and code samples that help customers get unblocked quickly
Support and guide customers through on-premise installations to Windows Server environments
Write clean, well-documented C# code against our .NET LTS platform and SQL Server data layer
Collaborate closely with internal product and engineering on customer feedback and integration patterns
Collaborate closely with internal program/project managers to ensure customer expectations are met
Become the “go to” person for lowest level technical support on customer and on premise projects

TECH STACK

C# / .NET LTS - Primary - must be strong
SQL Server - AWS-hosted
Docker (Linux arm64) - Container deployments
Windows Server - On-prem installations
Next.js / React - Nice to have

WHAT WE'RE LOOKING FOR

5+ years of professional C# development experience with solid .NET fundamentals
Comfort owning the customer relationship on technical projects — you enjoy calls, you write clearly, and you know how to manage expectations
Practical experience with SQL Server: query optimization, schema design, integrations
Familiarity with Docker and Linux-based deployment environments
Experience supporting on-premise software installations, ideally to Windows Server
Ability to translate fuzzy customer requirements into well-scoped technical plans

Nice to have: Front-end exposure to Next.js or React. You won't own it, but it helps to read the codebase.

YOU MIGHT BE A GREAT FIT IF...

You've worked at a software company where you were the technical bridge between product and customer
You genuinely enjoy the diagnostic side of integration work — figuring out why two systems aren't talking
You're comfortable negotiating technical requirements between multiple parties
You're unflappable when a customer's environment is "a little different" from the docs

BENEFITS

Paid sick days & holidays
Paid vacation
401k with company matching
Medical insurance
Flexible schedule
Work from home with occasional visits to the Seattle office

Sologic places a high priority on protecting customer data and we are certified in ISO 27001 and ISO 27017. We also have our SOC2 Type 2 attestation.

Everyone is expected to follow Sologic’s security and compliance processes, and uphold industry best practices.

EQUAL OPPORTUNITY

Pay: $120,000.00 - $155,000.00 per year

Benefits:

401(k) matching

Health insurance
Paid time off
