For the salad: Whisk the oil, white balsamic vinegar, salt and pepper in a large bowl. Add the arugula, radishes and pumpkin seeds. Toss to blend. Arrange the salad on a serving platter.
For the shrimp: Place the arrowroot in a small bowl. Gradually add the cider vinegar, stirring until the arrowroot dissolves. Mix in the jam, chipotle chile, 1/4 teaspoon of the salt and 1/4 teaspoon of the pepper.
In a large nonstick skillet, heat the oil over medium-high heat for 1 minute. Add the shrimp. Sprinkle with the remaining 1/4 teaspoon salt and 1/4 teaspoon pepper. Toss until almost cooked through, 2 to 3 minutes. Add the jam mixture to the skillet. Cook until the mixture is very thick and bubbling, stirring often, 1 to 2 minutes. Toss the shrimp until thickly coated with the glaze. Spoon the shrimp over the salad and serve.
