Thanks for taking time to stop by and take a look at the SharePoint / .net Developer role I posted here on LinkedIN, I appreciate it quite a bit. I realize that looking for work - especially now - kinda stinks. So, I am going to try and make this as pain free as possible. Allow me to introduce myself just a bit. My name is Tom Welke, I am Partner & VP at RSM Solutions, Inc. I have been recruiting technical talent for a long long time and been in the tech sector for longer than that. I'm saying all this not to gloat, I am saying this so that you know that you are actually dealing with a real, live, breathing human. Not a bot, not an AI engine. Like I said, if I can make this easier, I will gladly do my best to try. That being said, you will see some humor in this JD... So, let's get down to it... As with just about every role I work on, social fit is important. Granted, there will be some 'gotta have's otherwise someone's going to have a coronary' from a technical standpoint (you will see that as your read this JD)...but those social fit characteristics are really important as well. Here are some of 'em: This one is for my favorite law firm. Yep, there is such a thing... I have worked with them quite a bit over the past few years, so I know these guys pretty well. Sometimes, people will think that all law firms are the same. Starchy, stiff upper lip, and kinda dull. These guys are definitely not starchy or so ego-filled that you can't get anything done without an act of Congress. So, if you function well in an environment where - yes - they are professional, but also one where they focus on actually getting stuff done, you will do just fine here. There is a lack of micro-management here. But, here's the caveat. It means you don't need to be micro-managed. If you are the kind of person that does their best work wherever they go, and is thinking ahead as they work (in other words, if you go this way, you will run into a wall...so, you don't run into the wall and go a different direction), you will do just fine here as well. This role is being done onsite in downtown Chicago. We are really only looking to work with candidates that are already in the greater Chicago metro area for this role. In addition, I can only work with US Citizens of Green Card Holders for this one. So, if you are an H1, OPT, EAD, H4, F1, STEM Visa holder, I won't be able to work with you, unfortunately. This role is permanent and fully benefitted (life, dental, health, all the goodies) For this role, we are seeking - as you might have guessed from the title - a SharePoint Developer with .net development experience. This role is for someone who looks at their work, not as tasks, but from a wider angle lens. In other words, you will be working on everything from requirements gathering, documentation, process flow diagramming, dev, test and deployment. Along that process of seeing that 'wide angle lens', you will - inevitably - find that what is asked for isn't really going to solve the issue. So, if you have been that person that challenges assumptions, and asks clarifying questions, we will be on the right track. You will, primarily, work with SharePoint Online and Microsoft's development stack, including .Net, ASP.Net, VB.Net, SPFx, MVVM and MVC Patterns, and C#. You will be working on a mix of projects, including dev work from scratch, working off of apps that already exist, 3rd party integration work, and senior level support of your code. The teams you will be working with are risk & compliance, marketing and administration within the firm. You will be a part of a 9 person team. All of these team members are, primarily, .net architects and developers. You will be focusing, primarily, on SharePoint development in this role and working alongside your other teammates. Here are some of the main responsibilities (this is not an exhaustive list...most people reading this know by now that you will be working with a team...and 'other projects as assigned' are a standard with just about any dev role): Design, developer, validate & implement SharePoint and .net apps to solve complex challenges using SharePoint Online. Maintain, enhance and refactor existing SharePoint and .net based applications to optimize the existing application portfolio, while staying up to date with other dependencies. Manage data integration between SharePoint Online applications and 3rd party solutions using fun stuff like Stored Procedures, SSIS, DTS, SharePoint Lists and other data integration middleware. Here is what we are seeking At least 7 years of SharePoint development experience. This 7 years of experience will need to include experience with ASP.Net, VB.Net, C#, SPFx, MVVM, and MVC patterns. At least 2 projects in your background where you were the only SP or .net developer working on that project from start to finish. At least 6 years of experience with Sql Server 2019 or newer. This experience will need to include SSRS and SSIS. At least 5 years of experience with Azure DevOps or TFS. This should include build/release engineering, pipeline, management for software web applications, test manager and test automation. Experience with IIS administration would be great to see. Experience with IntApp Integrate (or similar tools like Biztalk, MQ, Oracle Fusion, etc) would be great to see. Experience with PowerAutomate, K2 BlackPearl, or IntApp Flow would be great to see. Experience with HTML, CSS, XML, JavaScript, VB Script, Python, TCL, or Pearl would be great to see.
